| [tycho-user] Put JUnit 5 eclipse-plugin-tests without legacy org.junit dependency? |
Hi, I have a Tycho (1.4.0) project where I want to use JUnit 5. According to the Wiki [1], I have to require both the org.junit.jupiter.api and the (legacy) org.junit bundles from my eclipse-plugin-tests. As I don't have legacy tests and find it annoying to have two versions of the @Test annotation on the class path (easy to pick the wrong one in an Import Quick Fix), I tried removing the org.junit dependency. Unfortunately, this results in a (non-fatal) exception during test execution: > WARNING: TestEngine with ID 'junit-vintage' failed to discover tests > java.lang.NoClassDefFoundError: org/junit/runner/manipulation/Filter > at org.junit.vintage.engine.discovery.VintageDiscoverer.<init>(VintageDiscoverer.java:48) > at org.junit.vintage.engine.VintageTestEngine.discover(VintageTestEngine.java:65) > at org.junit.platform.launcher.core.DefaultLauncher.discoverEngineRoot(DefaultLauncher.java:130) > at org.junit.platform.launcher.core.DefaultLauncher.discoverRoot(DefaultLauncher.java:117) > at org.junit.platform.launcher.core.DefaultLauncher.discover(DefaultLauncher.java:82) > at org.apache.maven.surefire.junitplatform.TestPlanScannerFilter.accept(TestPlanScannerFilter.java:56) > at org.apache.maven.surefire.util.DefaultScanResult.applyFilter(DefaultScanResult.java:102) > at org.apache.maven.surefire.junitplatform.JUnitPlatformProvider.scanClasspath(JUnitPlatformProvider.java:129) > at org.apache.maven.surefire.junitplatform.JUnitPlatformProvider.invoke(JUnitPlatformProvider.java:117) > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) > at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) > at java.lang.reflect.Method.invoke(Method.java:498) > at org.apache.maven.surefire.util.ReflectionUtils.invokeMethodWithArray2(ReflectionUtils.java:206) > at org.apache.maven.surefire.booter.ProviderFactory$ProviderProxy.invoke(ProviderFactory.java:161) > at org.apache.maven.surefire.booter.ProviderFactory.invokeProvider(ProviderFactory.java:84) > at org.eclipse.tycho.surefire.osgibooter.OsgiSurefireBooter.run(OsgiSurefireBooter.java:108) > at org.eclipse.tycho.surefire.osgibooter.AbstractUITestApplication$1.run(AbstractUITestApplication.java:35) > at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:40) > at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:185) > at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:5113) > at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:4666) > at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine$5.run(PartRenderingEngine.java:1173) > at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:338) > at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine.run(PartRenderingEngine.java:1062) > at org.eclipse.e4.ui.internal.workbench.E4Workbench.createAndRunUI(E4Workbench.java:155) > at org.eclipse.ui.internal.Workbench.lambda$3(Workbench.java:635) > at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:338) > at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:559) > at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:150) > at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:155) > at org.eclipse.tycho.surefire.osgibooter.UITestApplication.runApplication(UITestApplication.java:31) > at org.eclipse.tycho.surefire.osgibooter.AbstractUITestApplication.run(AbstractUITestApplication.java:120) > at org.eclipse.tycho.surefire.osgibooter.UITestApplication.start(UITestApplication.java:37) > at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:203) > at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:137) > at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:107) > at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:400) > at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:255) > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) > at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) > at java.lang.reflect.Method.invoke(Method.java:498) > at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:660) > at org.eclipse.equinox.launcher.Main.basicRun(Main.java:597) > at org.eclipse.equinox.launcher.Main.run(Main.java:1468) > at org.eclipse.equinox.launcher.Main.main(Main.java:1441) Explicitly selecting the "junit5" provider using a <providerHint> doesn't help; the tycho-surefire-plugin still insists to use the "junit-vintage" test engine under the hood. Does there exist a workaround that avoids the above exception being logged? Or should I file a bug?
