This would allow the user via the GUI or CLI to choose what happens when they provide no arguments to the launcher. The main options would be run and update-and-run. This would allow the launcher to seamlessly open Recaf without any intermediate steps or required user input.

In your readme, you're saying:

• Bundling JavaFX can work, but its your responsibility to ensure the bundled version is compatible with Recaf
• Ideally use a JDK that does not bundle JavaFX and let the launcher pull in JavaFX

This is, in fact, not true. When I try to run Recaf using java -jar launcher.jar run, I get the error:

No local cached version of JavaFX found.
- Try running with 'update-jfx'

Based on the code from src/main/java/software/coley/recaf/launch/commands/Run.java, it indeed checks only for the locally cached version of JavaFX and ignores any bundled version (line 61: JavaFxVersion javaFxVersion = JavaFxVersion.getLocalVersion();).
I don't want to force downloading JavaFX separately. The whole reason for using JDK with bundled JFX is to not occupy additional disk space for a copy of JavaFX for every Java app that might use it.

My proposal for a fix is:

• Do not make the check for local JavaFX mandatory
• Wrap the lines 73-80 in an if (javaFxVersion != null) and don't do classpathItems.addAll(javafxDependencies); if it's not true.

This will assume JavaFX is bundled with JDK and try to run Recaf with it. Of course, bundled JavaFX could probably be checked in some way (like how the Java runtime itself does when running a JAR with javafx Application subclass as the main class).

When trying to install Recaf 4.x with launcher 0.4.1 it hangs on fetching the artifact. No network usage listed in Task Manager above 32kbps which is baseline

I can't use Recaf 2 because I need to change an annotation

Same issue on Java 22

Here's the stdout generated when using Azul Zulu 21: stdout_zulu21.txt

Same thing with Eclipse Adoptium 17: stdout_adoptium17.txt

The exception java.lang.UnsatisfiedLinkError: 'java.lang.String com.sun.javafx.font.PrismFontFactory.regReadFontLink(java.lang.String)' is probably generated by some JavaFX incompatibility. I'm unsure if either of these runtimes have JavaFX bundled, but a quick find for jfx/javafx in the install directory yields nothing. Thanks in advance.

https://bugs.openjdk.org/browse/JDK-8325993

JavaFX 23 updates the compile target from 17 to 21. Recaf 4x currently is on 17 as a baseline. Before fetching newer versions than 22 the launcher should check if the current JVM is on version 21 or higher.

First time installing the launcher. When running java -jar recaf-launcher-0.1.3.jar update-jfx, it attempts to download dependencies into AppData\Roaming\Recaf\dependencies. In my case, the dependencies directory did not exist and the launcher did not make an attempt to create the directory automatically. This caused the dependency download to fail.

dependencies folder in appdata\recaf isnt created automatically :(((

Add jdk selection option + version check to recaf launcher

To be able to double click jars and to swifty open projects. It is common to make the argument of the runnable being a path to the destination to open.

As such, please add an argument to the 4.x launcher to open Recaf with he desired workspace (jar, directory, ...).

And does nothing

C:\java\jdk22\bin\javaw -jar recaf-launcher-0.4.1.jar

Hi. I want to make simple cli command to decompile jar file. With programs like text editors I can just specify filename after program name (notepad myfile.txt). But it doesn't work with this launcher. Where can I specify file to open? Or workspace to open or stuff like that.
Also headless mode doesn't seem to work for me, recaf still opens a window even when I use java (not javaw) and specify -x option. And there's no --help or anything

For example, when I open the launcher.jar it doesn't open, I don't see MessageBox with error, to understand what happened, I have to open recaf-launcher.log to find the line with an error.
In that case log is:

Attempting to resolve installed Recaf version...
Recaf jar file not found: 'C:\Users\u\AppData\Roaming\Recaf\recaf.jar'

It would be nice to see a MessageBox with error:

Recaf jar file not found:
``C:\Users\u\AppData\Roaming\Recaf\recaf.jar''.

I think it won't be a problem to make MessageBox display via jfx

Downloaded launcher 0.4.0, downloaded Java 22 x64 and installed that ahead of time. When I try to run recaf via the launcher, it downloads recaf and JavaFX, however there seems to be a class required that is not available.

 - java.version = 22.0.1
 - java.vm.vendor = Oracle Corporation
 - java.vm.version = 22.0.1+8-16

Currently the Recaf process is started with no arguments, but we'll want to allow specifying content like:

• Files to open as workspaces
• Scripts to run

Usage:

• For the GUI
  • A single jar path as an argument should pass that path as an input/workspace to Recaf when launched
  • A single java source file path as an argument should pass that path as a script to Recaf when launched
• For the CLI
  • The run and auto commands should have new --input and --script arguments for passing along to Recaf when launched

See: LaunchCommand

Just had a guy where the jars were incomplete, so using them in the URLClassLoader didn't load all the necessary classes.

Maven hosts the md5/sha1 of files. So this should be ezpz to add.
