Hello Word with Gradle

I am having problems on linux using Gradle and Netbeans (throw the Gradle plugin). I created a very simple test for that, here. Xramby suggested me that it is a problem with Netbeans since it relys on resources in the build folder.

But when I already asked on the Gradle forum and on the github page of the Gradle plugin, in both places I was told that is not gradle/netbeans related, rather a Jogl one.

They point my log here:

Yea it crashes in GL-code but the reason it crashes could still be that native libraries are not found. It could also be that your initalization is not correct or many other things :-)

I guess it is this line that crashes
"GLProfile glProfile = GLProfile.get(GLProfile.GL4);"

Is there any other way (other application) you could use to verify that the driver supports OpenGL 4?

I am also pretty sure it has to do with Gradle, but this is how I was told here and here..

The driver works fine, it runs flawless without using Gradle and I have GL 4.5

Does it work in command line without Netbeans? I use Gradle with LibGDX but not to run a JOGL program.

I have to try that

"gradle build" works for me when I build JogAmp's Ardor3D Continuation too. Which version of Gradle do you use?

It should be 2.4

I found a very interesting fact

If I use this configuration:

    ext.jogampVer = '2.3.2'
   
    repositories {
        mavenCentral()
        flatDir { dirs 'jogamp' }
    }
   
    dependencies {
        testCompile group: 'junit', name: 'junit', version: '4.11'
   
        compile ":jogl-all:$jogampVer"
        compile ":gluegen-rt:$jogampVer"
    }

It works on linux...

In my /jogamp I have `gluegen-rt`, `jogl-all` and the corresponding natives

But if I change the configuration back to

    ext.jogampVer = '2.3.2'
   
    repositories {
        mavenCentral()
    }
   
    dependencies {
        testCompile group: 'junit', name: 'junit', version: '4.11'
   
        compile "org.jogamp.jogl:jogl-all:$jogampVer"
        compile "org.jogamp.gluegen:gluegen-rt:$jogampVer"
        compile "org.jogamp.jogl:jogl-all:$jogampVer:natives-linux-amd64"
        compile "org.jogamp.gluegen:gluegen-rt:$jogampVer:natives-linux-amd64"
    }

It doesn't find the native library anymore...

I tried to substitute `compile` with `runtime` for the natives, but I had no success..

What's wrong? Why cannot it find the natives?

This is the error

    Exception in thread "main" java.lang.UnsatisfiedLinkError: Can't load library: /home/elect/IdeaProjects/Test/natives/linux-amd64//libnativewindow_awt.so

This path is exactly that one inside the native I am trying to include

It should look for the native libraries in the temporary cache. Please enable all logs. Something might prevent their extraction.
