There are only two things that affect whether the launcher class can be found:

1. eclipseLocation must point to a valid Eclipse installation.
2. The equinoxLauncherPluginVersion property must match the version of the org.eclipse.equinox.launcher bundle.

There is nothing specific to PDE Build in all of this, we’re just configuring the classpath of a regular Ant java task. If you’ve set the launcher version properly, can you double-check that eclipseLocation points to a valid Eclipse installation?

I seem to be getting an error in your tutorial. Any input on fixing the issue would be greatly appreciated.

pde-build:

[java] exception in thread “main” java.lang.NoClassDefFoundError: org/eclipse/equinox/launcher/Main
[java] Caused by java.lang.classnotfoundexception: org.eclipse.equinox.launcher.main

It can’t seem to find the “main” class that is necessary to run the equinox launcher.

I’ve struggled with this as well. The only thing I came up with was to scan the JUnit output to determine if any tests failed. If you figure out a better way, I’d be very interested :-)

I have one more question. Is there any possibilities for that if I would like to see a build failed status when any of the JUnit tests fails? Currently I get a build failed state only if the build part fails but I get a build success state even when some JUnit tests fail.

Can I somehow configure headless build or ETF so that it return with failed status when a JUnit test fails?

Thanks in advance!

If EMMA is running, I’m not sure why the process is hanging at this point. Perhaps there is some issue with the EMMA instrumentation process itself?

Thank you very much for your quick reply.

You was right. The eclipselocation was not pointing to a valid Eclipse installation.

The build is now successful but the test process takes a very very long time (hours). After many hours it is still at the following step :

[java] [zip] Building zip: c:\helloworld-build\features\org.eclipse.pde.build.container.feature\org.eclipse.pde.build.container.feature_1.0.0.log.zip
[java] [delete] Deleting directory c:\helloworld-build\features\org.eclipse.pde.build.container.feature\feature.temp.folder
[java] [unzip] Expanding: c:\helloworld-build\features\org.eclipse.pde.build.container.feature\org.eclipse.pde.build.container.feature_1.0.0.log.zip into c:\helloworld-build\I.HelloWorld\compilelogs
[java] BUILD SUCCESSFUL
[java] BUILD SUCCESSFUL
[java] Total time: 3 minutes 11 seconds
test:
[unzip] Expanding: c:\helloworld-build-target\eclipse-SDK-3.4.1-win32.zip into c:\helloworld-build\test
[unzip] Expanding: C:\Java\workspaces\Exemples\com.rcpquickstart.helloworld.build-and-test\eclipse-test-framework-3.4.1.zip into c:\helloworld-build\test
[unzip] Expanding: c:\helloworld-build\I.HelloWorld\HelloWorld-win32.win32.x86.zip into c:\helloworld-build\test
[move] Moving 50 files to c:\helloworld-build\test\eclipse
[instr] processing instrumentation path …

So i have not the test-results.xml file which interest me the most…

Have you got any idea of what’s happening?

Thank you for all….

Thank you for this article which is very helpful.

I have errors while executing your instructions :

pde-build:

Have you got any idea of the source of the problem?

Thank you for all.

Thank you very much, and sorry for not replying earlier.
It was a great help. That’s solved my problem.
