Thanks for the bug Steffen. Would it make sense to change the JUnit dependency to this: @org.junit;bundle-version="[3.8.2,4.0.0)"@ The down-side of changing the dependency version constraint is that running unit tests from the Ecilpse UI results in an error, since JUnit4 is automatically selected in the launch configuration. Changing it to JUnit3 works - but it's a pain to have to do that.
Yes, that works. Alternatively you can limit the use of JUnit classes to JUnit 3 or add a dependency on org.junit4. We have done the latter for bundles in the Mylyn Reviews project to make JUnit 4 APIs available.
added dependency to org.junit4
The change has caused a slightly different error. We may need to change the way integration tests are handled to address this. pre.. ------------------------------------------------------- T E S T S ------------------------------------------------------- Running org.eclipse.mylyn.tests.AllTests Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.011 sec <<< FAILURE! initializationError(org.eclipse.mylyn.tests.AllTests) Time elapsed: 0.002 sec <<< ERROR! java.lang.LinkageError: loader constraint violation: loader (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) previously initiated loading for a different type with name "junit/framework/Test" at org.eclipse.mylyn.tests.AllNonConnectorTests.addTests(AllNonConnectorTests.java:58) at org.eclipse.mylyn.tests.AllTests.suite(AllTests.java:26) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.junit.internal.runners.SuiteMethod.testFromSuiteMethod(SuiteMethod.java:34) at org.junit.internal.runners.SuiteMethod.<init>(SuiteMethod.java:23) at org.junit.internal.builders.SuiteMethodBuilder.runnerForClass(SuiteMethodBuilder.java:14) at org.junit.runners.model.RunnerBuilder.safeRunnerForClass(RunnerBuilder.java:57) at org.junit.internal.builders.AllDefaultPossibilitiesBuilder.runnerForClass(AllDefaultPossibilitiesBuilder.java:29) at org.junit.runners.model.RunnerBuilder.safeRunnerForClass(RunnerBuilder.java:57) at org.junit.internal.requests.ClassRequest.getRunner(ClassRequest.java:24) at org.apache.maven.surefire.junit4.JUnit4TestSet.<init>(JUnit4TestSet.java:45) at org.apache.maven.surefire.junit4.JUnit4DirectoryTestSuite.createTestSet(JUnit4DirectoryTestSuite.java:56) at org.apache.maven.surefire.suite.AbstractDirectoryTestSuite.locateTestSets(AbstractDirectoryTestSuite.java:96) at org.apache.maven.surefire.Surefire.createSuiteFromDefinition(Surefire.java:209) at org.apache.maven.surefire.Surefire.run(Surefire.java:156) at org.eclipse.tycho.surefire.osgibooter.OsgiSurefireBooter.run(OsgiSurefireBooter.java:72) at org.eclipse.tycho.surefire.osgibooter.AbstractUITestApplication$1.run(AbstractUITestApplication.java:35) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:134) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:3468) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3115) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2405) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2369) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2221) at org.eclipse.ui.internal.Workbench$5.run(Workbench.java:500) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:493) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:113) at org.eclipse.tycho.surefire.osgibooter.UITestApplication.runApplication(UITestApplication.java:31) at org.eclipse.tycho.surefire.osgibooter.AbstractUITestApplication.run(AbstractUITestApplication.java:114) at org.eclipse.tycho.surefire.osgibooter.UITestApplication.start(UITestApplication.java:37) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:194) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:368) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:559) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:514) at org.eclipse.equinox.launcher.Main.run(Main.java:1311) at org.eclipse.equinox.launcher.Main.main(Main.java:1287)
I've temporarily reverted the bundle constraint to the following: @org.junit;bundle-version="3.8.2"@ Steffen is there an easy way for me to test this change on Galileo - how do you run the build?
Do you know what is causing the error? You can run integration tests like this from the top-level integration repository: mvn -Pgalileo clean verify -Dmaven.test.skip=true -Dmaven.test.error.ignore=true -Dmaven.test.failure.ignore=true -Dpack.skip=true -Dexplicit-target=true -Dtest.all.skip=false
That error looks very hard to diagnose - possibly a ClassLoader problem with multiple JUnit jars on the classpath?

Did you run it from this repository? http://git.eclipse.org/c/mylyn/org.eclipse.mylyn.all.git Triggering https://hudson.eclipse.org/hudson/job/mylyn-integration-e3.5/ wouldn't help since it runs against the integration repository which needs to be explicitly updated by a committer of the mylyn top-level project. I'll try to take a look at this problem later next week. Let's not worry about it for now. Another way to run tests is to install bundles into the local Maven cache and then run 'mvn -Pgalileo integration-test' in org.eclipse.mylyn/org.eclipse.mylyn.tests.
(In reply to comment #8) > Did you run it from this repository? > http://git.eclipse.org/c/mylyn/org.eclipse.mylyn.all.git No. Cloning from that URL doesn't work - however I did clone what I think is the same repo over ssh.

You would have to initialize and update the submodules first to run a build across all projects. Regarding the LinkageError it seems that org.junit4 conflicts with the org.junit bundle. I assumed that org.junit4 re-exports packages from org.junit but that does not appear to be the case on Eclipse 3.5. This seems only have changed in Eclipse 3.6 or later. I am tempted to add org.junit 4.8 to the target definition and to mandate that all tests require org.junit 4.0 or later to make sure all bundles get wired to the same version. I'll send out an email to gather some input.
I added org.junit 4.8.2 to the 3.4 and 3.5 target. We'll use that bundle for running all tests now.
