Gradle, error could not find or load main class 'test.Main'
I implemented Gradle on one of my projects. I use Netbeans 8.02 with the gradle plugin.
Structure is as it should be, sources are located under jgli/src/main/java/ , resources under jgli/src/main/resources/
The Main class is jgli/src/main/java/test/Main.java
If I run it through the ide, it runs on windows, it crashes on linux. That's why I am trying to run it through the console right now:
java -jar jgli.jar
But I keep getting:
Error could not find or load main class 'test.Main'
This is my build.gradle
apply plugin: 'java'
sourceCompatibility = '1.8'
[compileJava, compileTestJava]*.options*.encoding = 'UTF-8'
// NetBeans will automatically add "run" and "debug" tasks relying on the
// "mainClass" property. You may however define the property prior executing
// tasks by passing a "-PmainClass=<QUALIFIED_CLASS_NAME>" argument.
//
// Note however, that you may define your own "run" and "debug" task if you
// prefer. In this case NetBeans will not add these tasks but you may rely on
// your own implementation.
if (!hasProperty('mainClass')) {
ext.mainClass = ''
}

mavenCentral()
// You may define additional repositories, or even remove "mavenCentral()".

testCompile group: 'junit', name: 'junit', version: '4.10'
compile 'org.jogamp.jogl:jogl-all-main:2.3.2'
compile 'org.jogamp.jogl:nativewindow-main:2.3.2'
compile 'org.jogamp.jogl:newt-main:2.3.2'
compile 'org.jogamp.gluegen:gluegen-rt-main:2.3.2'
}
jar {
manifest {
attributes 'Main-Class': 'test.Main'
}
}
I just modified the dependecies section and added the manifest part.
I tried to add 'test.Main' to the ext.mainClass, but it changed nothing..
Here you can download the jar.
This is my MANIFEST.MF :
Manifest-Version: 1.0
Main-Class: test.Main
Main.class is properly located inside the jar. Main.java has the package declaration package test;
Tried also
apply plugin: 'application'
mainClassName = 'test.Main'
without success..
What am I missing?
I've just found your git repository and sources of your Main class, seems that it implements some interface, which is provided in your dependencies:
import com.jogamp.newt.event.KeyListener;
import com.jogamp.opengl.util.GLEventListener;
public class Main implements GLEventListener, KeyListener {
...
Which are from some of your dependencies libs:
compile 'org.jogamp.jogl:jogl-all-main:2.3.2'
compile 'org.jogamp.jogl:nativewindow-main:2.3.2'
compile 'org.jogamp.jogl:newt-main:2.3.2'
compile 'org.jogamp.gluegen:gluegen-rt-main:2.3.2'
In that case, your dependencies must be in your class path, while you running your Main class. Try to provide -cp option to point the path, where your dependecies could be found.
Normally you set the main-class in your build file as follows:
mainClassName = 'package.MainClassName'
Do you pass it as Parameter? -> hasProperty Then you had to run your build something like: gradle -PmainClass=MyClass build
