Scaffold command fails on OSX about wuff HOT 28 CLOSED

OK, I'll have a look.

from wuff.

I looked through my code, result: config for Linux and Windows implemented, for OSX - not. Will try to fix it tomorrow.

from wuff.

I'm afraid the problem persists with version 0.0.7

Perhaps it would be a good idea to collaborate on a branch before pushing another release? ;-)

from wuff.

You are right. I was over-confident it just works 😄. I created a branch "macosx".

The heart of the beast is here:
https://github.com/akhikhl/wuff/blob/macosx/libs/wuff-plugin/src/main/resources/org/akhikhl/wuff/defaultConfig.groovy
This file contains all configurations for all eclipse versions.

from wuff.

This part deals with detecting current OS and current architecture:
https://github.com/akhikhl/wuff/blob/macosx/libs/wuff-plugin/src/main/groovy/org/akhikhl/wuff/PlatformConfig.groovy#L46-L56
I forgot to update this part.
Could you, please, have a look and give advice what should be there for Mac OS?

from wuff.

Evaluating those properties on Groovy Console results in

groovy> println System.getProperty('os.name') 
groovy> println System.getProperty('os.arch') 

Mac OS X
x86_64

from wuff.

I added these two lines:
https://github.com/akhikhl/wuff/blob/macosx/libs/wuff-plugin/src/main/groovy/org/akhikhl/wuff/PlatformConfig.groovy#L51-L52

Could you, please, try it?

git clone [email protected]:akhikhl/wuff.git
cd wuff
git checkout macosx
gradle build
cd examples/RcpApp-1
gradle build

from wuff.

Looks like you may need to tweak the build files in order to locate locally built components

Ah, this is the same as with Wuff: Unpuzzle repo is not included at jcenter yet.
Temp solution:

git clone [email protected]:akhikhl/unpuzzle.git
cd unpuzzle
gradle build

then build Wuff.

from wuff.

Or just add:

buildscript {
  repositories {
    maven { url 'http://dl.bintray.com/akhikhl/maven'  }
  }
}

to wuff/build.gradle, then it should compile.

from wuff.

When scaffolding, you might see messages saying that Wuff cannot create extension points. These should be treated as warnings, not errors (scaffolding works despite of these messages).
I already fixed it on Wuff master.

from wuff.

I'm afraid the error persists, even after building and installing unpuzzle (0.0.13 is the version I've got from cloning the repo)

:libs:unpuzzle:downloadEclipse
Downloading file: http://mirror.netcologne.de/eclipse//technology/epp/downloads/release/kepler/SR2/eclipse-jee-kepler-SR2-null-x86_64.null

from wuff.

Hold on, together we will fix it 😄.
The error message means - architecture is chosen correctly, but OS is still not detected. Could you, please, insert two lines at line 53 of PlatformConfig:

println "System.getProperty('os.name') -> ${System.getProperty('os.name')}"
println "System.getProperty('os.name').equalsIgnoreCase('Mac OS X') -> ${System.getProperty('os.name').equalsIgnoreCase('Mac OS X')}"

then do gradle build on Wuff and on app? What's the message?

from wuff.

I've got the following result

System.getProperty('os.name') -> Mac OS X
System.getProperty('os.name').equalsIgnoreCase('Mac OS X') -> true

from wuff.

Good, I look further into sources.

from wuff.

I just simulated your environment by forcibly setting current_os = 'Mac OS X' at line 46 of PlatformConfig.groovy and things are working fine. The program downloads, unpacks and installs eclipse-jee-kepler-SR2-macosx-cocoa-x86_64.tar.gz.
You are on gradle 2.0-rc-1, aren't you? I'll try switching to it to see if problem is related to gradle version.

from wuff.

The bug does not depend on gradle version. I tried it, Wuff works just fine with gradle 2.0-rc-1 (in my environment).
Could you, please, insert the line:

 println "suffix_os=${suffix_os}, current_os=${current_os}, suffix_os[current_os]=${suffix_os[current_os]}"

at line 333 of file wuff/libs/wuff-plugin/src/main/resources/org/akhikhl/wuff/defaultConfig.groovy?
Check: the next line must be:

source "$eclipseMirror/eclipse//technology/epp/downloads/release/kepler/SR2/eclipse-jee-kepler-SR2-${suffix_os[current_os]}${suffix_arch[current_arch]}.${fileExt_os[current_os]}"

then do gradle build on Wuff and your app and tell me, what's the output?

from wuff.

I don't know what to tell you. The change doesn't go through. For some reason the build continues to point to the old binaries, the println statements never get executed :-(

from wuff.

Ah, that's good news 😄
Means: there's discrepancy in dependency include somewhere. We include old code and it gets executed. Let's look at the example app you were compiling:

• does it use wuff version 0.0.7 or older version? Or is it "+" for version number?
• what's the sequence of repositories? Is mavenLocal() included before jcenter() in buildscript.repositories?

from wuff.

I'm not even able to compile wuff at all :-( Here's the current diff based on the macosx branch

diff look fine, thank you.
There are two reasons, why it doen't compile for you:

1. there are unit-tests in wuff-plugin, that rely on eclipse being downloaded and installed, if not, they attempt to download and install eclipse.
2. The project "libs/unpuzzle" downloads and installs eclipse plugins. If there are errors in this process, Wuff compilation stops.

Could you, please, try the following:

cd libs/wuff-plugin
gradle install

This way we skip unit-tests and "libs/unpuzzle" and just compile and install Wuff to local maven repo.

When it works, try running tasks on sample application.

from wuff.

I was able to reproduce the last error you described. The source is the following: unpuzzle contains duplicate class PlatformConfig and another configuration of repositories, that is used by wuff/libs/unpuzzle.

I am now fixing it now. I'll update when fixed code is available at github.

This is exactly the case when code duplication gets nasty and costs time. Sorry.

from wuff.

Now the error seems to be solved. Unpuzzle and Wuff compile smoothly in simulated Mac OS X environment (current_os set to "Mac OS X" instead of system property).

Could you, please, try once more? Your help is very much appretiated. Many people on Mac OS X will surely enjoy compiling Eclipse plugins and apps with gradle.

1. please do git pull on unpuzzle and switch to "macosx" branch
2. do git pull on wuff, stay at "macosx" branch
3. do gradle build on unpuzzle
4. do gradle build on wuff
5. try scaffolding/building/running an example program from tutorial

important: unpuzzle stays on version 0.0.13. Wuff version is now 0.0.8. If your sample app uses explicit version number, please upgrade to 0.0.8.

from wuff.

That did it. I was able to invoke gradle tasks --all and gradle run on the sample RPCapp project, however there was a problem with thread access

I believe this is a well know problem when running SWT on OSX. You must specify an additional JVM flag -XstartOnFirstThread.

Great that it compiles :) could you, please, do 'build gradle' on example
program, open 'build/output/appname' and add jvmarg to corresponding .sh
script? Will modified script run?

Hi Andres,
Sorry, was busy with other things in the mean time.
News: I added -XstartOnFirstThread parameter to macosx-specific products, as well as to "run" and "debug" tasks, when current OS is Mac OS X.
Could you, please, pull changes from github to wuff, "gradle build", then try example project?
I would be rather thankful for the results 😄

from wuff.

Holy Smokes! It's alive! no additional configuration was needed. I was able to run examples/RcpApp-1/MyRcpApp with just gradle run. Thank you! 😄

from wuff.

I'm happy to hear that it works on Mac OS X as well 🌞
So I do new release? Hopefully sooner than later, with growing user base and improved documentation on all features, it can get out of beta status.

from wuff.
