Any help would be appreciated.

The main helper.jar correctly specifies api-version: 1.13 in the plugin.yml, but all the other modules are missing that property, forcing the server to load them in legacy mode unnecessarily.

Description of the Bug

1.Hi Developers im new to coding. i tried to make this video uploading app to my firebase storage but im not that good at coding so im stuck at this problem. when upload button is pressed the filechooser is opened and if i select a file it gets uploaded to the firebase But if i cancel and close the filechooser it gives an error.

Considering that Nashorn is deprecated now with Java 11 and may get removed in the future would I suggest to switch to a different engine.

I am trying to use helper for the sidebar scoreboards. I added helper as a dependency in maven and used this:

<dependency>
        <groupId>me.lucko</groupId>
        <artifactId>helper</artifactId>
        <version>5.6.5</version>
        <scope>provided</scope>
    </dependency>

I also added the helper plugin to my server. Downloaded from https://ci.lucko.me/job/helper/lastSuccessfulBuild/artifact/helper/target/helper.jar. I only used the base helper as that is all I need. I also added helper as a depend in my plugin.yml, but even then I still get this error https://bytebin.lucko.me/bQimttSvmd
My server verion:
This server is running CraftBukkit version git-PaperSpigot-"4c7641d" (MC: 1.8.8) (Implementing API version 1.8.8-R0.1-SNAPSHOT)
Does anyone know why, or is this potentially a helper bug.

I've encountered an error when using PacketScoreboardProvider in my code:
Scoreboard scoreboard = Services.load(PacketScoreboardProvider.class).getScoreboard();

It caused an error when I joined the server:
https://hastebin.com/alijexifil.md

Maybe some method that was used is modified in future nms versions? I'm using 1.14.4 latest stable version

As the title says, i want to suggest a migration from Text3 which Helper now comes with to Adventure

Adding cooldowns to the Command Builder would be fantastic. Usage might look like:

.cooldown(30, TimeUnit.SECONDS)
or
.playerCooldown(30, TimeUnit.SECONDS) and .serverCooldown(30, TimeUnit.Seconds)

Implementation might be best based on Guava's CacheBuilder seen here.

Tagging @leonardo-dgs for being the only person who has made a PR in some time and already has some experience working with the Command system.

When I run it on the server it doesn't return the expected result.

Smaller partition size for clearer demonstration (32 partitions):

EDIT: I'm using the main helper module, version 5.6.2, with a standalone plugin (version 5.6.4).

It is completely incomprehensible how to use your api.
How do I serialize/deserialize a class? Class -> Hcon -> Class
How to work with the config node tree?
How to add a node? All I get when I try to directly add a node to the map is

https://spark.lucko.me/zhXDc5BPH6

so, I put helper & helper-redis on my server, but helper-redis can't connect to redis because the class org/slf4j/LoggerFactory can't be found which is used by jedis, I have put the same plugins on another server which have a few other plugins and I somehow don't get this issue on there.

[10:58:16 INFO]: [helper-redis] Disabling helper-redis v1.2.1

Your project, lucko/helper, depends on the outdated library FastClasspathScanner in the following source files:

• helper-js/src/main/java/me/lucko/helper/js/HelperJsPlugin.java

FastClasspathScanner has been significantly reworked since the version your code depends upon:

• a significant number of bugs have been fixed
• some nontrivial API changes have been made to simplify and unify the API
• FastClasspathScanner has been renamed to ClassGraph: https://github.com/classgraph/classgraph

ClassGraph is a significantly more robust library than FastClasspathScanner, and is more future-proof. All future development work will be focused on ClassGraph, and FastClasspathScanner will see no future development.

Please consider porting your code over to the new ClassGraph API, particularly if your project is in production or has downstream dependencies:

• https://github.com/classgraph/classgraph/wiki/Porting-FastClasspathScanner-code-to-ClassGraph
• https://github.com/classgraph/classgraph/wiki/Code-examples
• https://github.com/classgraph/classgraph/wiki/ClassGraph-API

Feel free to close this bug report if this code is no longer in use. (You were sent this bug report because your project depends upon FastClasspathScanner, and has been starred by 57 users. Apologies if this bug report is not helpful.)

Unable to build project due to the lack of shadow-bukkit version 1.3-SNAPSHOT on a Maven repo.

We're trying to do some Helper work for 1.13.2 as it's the only thing left for one of our entire gamemodes, that heavily depends on it, to function. My last roadblock is the jenkins issue above, which you've stated you experience as well.

It would be amazing if you could fix this some time for us <3

Got this PaginatedGui :

public class TitlesGui extends PaginatedGui {

    private static final MenuScheme DECORATION_SCHEME = new MenuScheme()
            .mask("100000001")
            .mask("100000001")
            .mask("100000001");

    private static final MenuScheme TITLES_SCHEME = new MenuScheme()
            .mask("011111110")
            .mask("011111110")
            .mask("000000000");

    private static final MenuScheme RESET_BUTTON_SCHEME = new MenuScheme()
            .maskEmpty(2)
            .mask("000010000");

    public TitlesGui(Player p) {
        super(paginatedGui -> new ArrayList<>(), p,
                PaginatedGuiBuilder.create().lines(3).title("Mes titres")
                        .itemSlots(TITLES_SCHEME.getMaskedIndexesImmutable())
                        .nextPageSlot(new MenuScheme()
                                .maskEmpty(2)
                                .mask("001000000")
                                .getMaskedIndexes().get(0))
                        .previousPageSlot(new MenuScheme()
                                .maskEmpty(2)
                                .mask("000000100")
                                .getMaskedIndexes().get(0))

                                .name("&6Page précédente")
                                .build())
        );
        updateContent(getTitles());
    }

    public List<Item> getTitles() {
        List<Item> content = new ArrayList<>();
        for (Title title : VikicraftTitles.getTitles()) {
            if (!VikicraftTitles.hasUnlocked(getPlayer(), title)) continue;

            ItemStackBuilder itemStack = title.buildItem();

            if (title.equals(VikicraftTitles.getTitle(getPlayer()))) {
                itemStack.enchant(Enchantment.LUCK);
                itemStack.flag(ItemFlag.HIDE_ENCHANTS);
            }

            Item item = Item.builder(itemStack.build()).bind(ClickType.LEFT, () -> {
                VikicraftTitles.setTitle(getPlayer(), title);
                Players.msg(getPlayer(), "&aTon titre a été changé en "+title.getTag());
                updateContent(getTitles());
                redraw();
            }).build();

            content.add(item);
        }

        return content;
    }

    @Override
    public void redraw() {
        super.redraw();

        if (isFirstDraw()) {
            // decoration
            DECORATION_SCHEME.newPopulator(this)
                    .acceptIfSpace(ItemStackBuilder.of(Material.STAINED_GLASS_PANE).buildItem().build());

            // reset button
            Item resetButton = Item.builder(
                    ItemStackBuilder.of(Material.BARRIER)
                            .name("&cRetirer mon titre")
                            .build()
            ).bind(ClickType.LEFT, () -> {
                VikicraftTitles.setTitle(getPlayer(), null);
                Players.msg(getPlayer(), "&aTon titre a été retiré.");
                updateContent(getTitles());
                redraw();
            }).build();

            RESET_BUTTON_SCHEME.newPopulator(this)
                    .acceptIfSpace(resetButton);
        }
    }

}

It gives me this error, tried to fix it but it seems it's helper's side :

For example I have 2 files: lang.yml and config.yml. How to get teamName field from lang.yml and set the delay value to 40 in the config.yml?

Tested both on OpenJDK16 and OpenJDK16-openj9
Also referencing #8.

Suggestion for the ability to relocate the dependencies download at runtime.

For persistence and ease of end-user modification (of titles and menu schemes, for example).

This might also include Item serialization. I'm aware the backing ItemStack is serializable, but it is done in such a way which is not user-friendly (version numbering, dirty metadata, et al.). It's possible that #84 may need to be resolved before this can be attempted.

It would be useful to have the possibility to set a tab completer handler (to tab-complete subcommands) like how can be registered the command handler with FunctionalCommandBuilder#handler.

Hey, I was testing java 16 and noticed this helper-sql error on bootup. Im not sure if it's harmful because all our plugins that use helper-sql seem to work fine.

So when I add helper as a dependency to my gradle, relocations of some dependencies aren't made in some classes. Like in the
ExtendedJavaPlugin class and ConfigFactory for instance.


Perhaps it's not going to be like that but when looking at one of the dependencies classes like ConfigurationNode, we can see that it is relocated which makes no sense since why would the class come from the original package as you can see in the screenshots if a relocated one is present. I can make a pr but I'd probably change the project from maven to gradle then if that would be okay.

It would be useful to have a BungeeCord module helper-bungee, and have a module with all code that does not rely on any server code like helper-common, and a module helper-bukkit.

We continue to get the following errors on one of our plugins that uses helper for a /booklet feature we use:

https://pastebin.com/raw/98PgU3Di

The error mentions STAINED_GLASS_PANE however nowhere in our code do we specify STAINED_GLASS_PANE.

Any help would really be appreciated.

https://pastebin.com/pMftVE1Z is spammed in console each time a GUI that is paginated has the forward/back buttons pressed when you're on the limits of the pages (ie, pressing back on page 1, pressing next on the last page.)

• This is the location of the forward/back buttons

• If I click here, on the last page, it throws that error. (Same with the back on the first page.)

Repeatedly clicking on it allows the current page to be past the index, requiring to hit the back buttons multiple times to return to valid pages.

Hi,

It gets Events fine (yes, I imported the right one) but #subscribe can't.

Helper doesn't works for some things with 1.14, it needs updating

i had an IllegalArgumentException when opening a paginated gui and i think it is caused by this:

As you can see there the material names are not valid. this is in the StandardSchemeMappings class.

Here is the error:

Hey, the async option from the Executors doesn't limit the number of threads that can be used in the pool, users have to be very careful when using that to not get an out of memory, a proper usage of it would be to limit the number of threads.

me.lucko.helper.menu.Gui contains a "player" field which is private and used by the class. Add the ability to keep a list of players or tell me the easiest way to open the same inventory for many players without inheriting this class.

If you register a command with a permission with Helper, it tab-completes even for players that doesn't have the permission, to fix this, when Helper registers a command, it should use default Bukkit Command#setPermission() and Command#setPermissionMessage().

Although this isn't an error with the API itself it's an issue using the documentation.
Whenever I click the wiki and attempt to click any of the sub categories the page doesn't change.
Thanks.

Here's an example code:

Events.subscribe(PlayerJoinEvent.class)
    .name("listenerA") // Optional, and by adding it you can reference it
    .handler(e -> e.setJoinMessage("A"));

Events.subscribe(PlayerJoinEvent.class)
    .name("listenerB")
    .mustRunAfter("listenerA") // Still: Optional. This will ensure that the event will be handled after listener A
    .mustRunBefore("listenerC") // You get the idea: it will ensure that the event will be handled before listenerB
    .handler(e -> e.setJoinMessage("B"));

Events.enableUnexistingListenerWarning(); // Check the code below

Events.subscribe(PlayerJoinEvent.class)
    .name("listenerC")
    .mustRunBefore("listenerB") // B must run before C, and C also must run before B: conflict. 
    // Throwing an exception with stack to let the developer know what is causing it 
    // (Sometimes it can get really complicated, for example, A must run after B must run after C... and must run after A)
    .mustRunAfter("listenerThatDoesntExist") // If listener doesn't exist and listener has been registered for over
    // <a configurable value> seconds, it will send a warning message to the console to let the developer know they probably
    // mistyped the listener name
    // Well, if it's in production state, developers probably don't want there to be a warning message in user's terminal,
    // that's why there's a function: `enableUnexistingListenerWarning()`, so developer can check if it's development build,
    // and enable it if needed
    .disableListenerNotExistingWarning() // With this, the listener can be not existing, and it won't print a warning message
    // So if listener is going to be registered later, it won't print the message
    .handler(e -> e.setJoinMessage("B"));

You can do it with a topological sorting algorithm, it would help a lot of developers.

(In my previous plugins, event priority gets really complicated and gets more than 5 layers, so in the end, I decided to code my own Event system instead of using an existing one, and having to figure out which priority should it be is very annoying and very hard to refactor. For example: If you want to insert an listener between A and B, you'll have to change everything before A or everything after B, having mustRunAfter and mustRunBefoer makes it way easier, so if plugin developers want to do something like damage processing in order, they can do it without painfully figuring out what priority should it be.)

I know it sounds impossible because Bukkit's event system is really not that great.

The only way I can think of to implement it is to have a custom event system, and have the main listener that listens to every single event, and call listeners.
But I don't really know how you actually listen to every event since there can be custom events, a way would be attaching to the server JVM instance, modifying the bytecode of "callEvent" and adding instructions that call an inner function of this library.

Another way to listen to all events is by using reflection, going through every plugin class loader, and finding every class that extends Event class. It sounds more possible but there can be some limitations like

1. takes around 1~2 seconds to start the server
2. Hacks like plugman won't work
   But it's less stupid than attaching into JVM and adding bytecodes, but it will be slower. Probably make 2 of them and make it configurable?

It may sound really stupid, but it will actually help a lot of people trying to develop complicated plugins.

Hi there,

Currently working on upgrading some of the projects that use Helper to 1.17. With 1.17, we also know that it is a Java 16 requirement. When changing to development on strict Java 16, there seems to be some reflection issues in Helper. Here's a copy of a stacktrace.

https://paste.helpch.at/iridajohuy.cpp

Could you add support for checksums to the MavenLibrary annotation to verify the integrity of the downloaded files? Maybe with the default value of an empty string to ignore it.

I made a plugin using this library and I didn't use any of the NPC features, but during startup I get this error.

Seems to happen with any server version compatible with helper so it seems to be a plugin-to-plugin incompatibility. It's most likely "NexEngine" modifying traits in Citizens and then helper attempts to do the same.

Could redis be updated to at least 2.10.1?
