Using the Virgo IDE tooling with the Virgo kernel, a clean rebuild under Eclipse results in missing manifests. To recreate, build the kernel using ant and then run StandardKernelIntegrationTests (in org.eclipse.virgo.kernel.test) as a JUnit test under Eclipse and it will pass. Then clean/rebuild the project org.eclipse.virgo.kernel.artifact under Eclipse after which re-running the unit test fails with the plugin conversion error below due to there not being a manifest in target/classes. org.osgi.framework.BundleException: Error converting plugin at /Users/glynnormington/eclipse/virgo/org.eclipse.virgo.kernel/org.eclipse.virgo.kernel.test/target/org.eclipse.osgi/bundles/41/1/bundlefile. at org.eclipse.core.runtime.internal.adaptor.EclipseStorageHook.generateManifest(EclipseStorageHook.java:451) at org.eclipse.core.runtime.internal.adaptor.EclipseStorageHook.getGeneratedManifest0(EclipseStorageHook.java:428) at org.eclipse.core.runtime.internal.adaptor.EclipseStorageHook.getGeneratedManifest(EclipseStorageHook.java:397) at org.eclipse.core.runtime.internal.adaptor.EclipseStorageHook.createCachedManifest(EclipseStorageHook.java:392) at org.eclipse.core.runtime.internal.adaptor.EclipseStorageHook.getManifest(EclipseStorageHook.java:512) at org.eclipse.osgi.internal.baseadaptor.BaseStorage.loadManifest(BaseStorage.java:316) at org.eclipse.osgi.internal.baseadaptor.BundleInstall.begin(BundleInstall.java:82) at org.eclipse.osgi.framework.internal.core.Framework.installWorkerPrivileged(Framework.java:930) at org.eclipse.osgi.framework.internal.core.Framework$1.run(Framework.java:838) at org.eclipse.osgi.framework.internal.core.Framework$1.run(Framework.java:1) at java.security.AccessController.doPrivileged(Native Method) at org.eclipse.osgi.framework.internal.core.Framework.installWorker(Framework.java:897) at org.eclipse.osgi.framework.internal.core.Framework.installBundle(Framework.java:833) at org.eclipse.osgi.framework.internal.core.BundleContextImpl.installBundle(BundleContextImpl.java:137) at org.eclipse.osgi.framework.internal.core.BundleContextImpl.installBundle(BundleContextImpl.java:131) at org.eclipse.virgo.osgi.launcher.FrameworkBuilder.installAndStartBundles(FrameworkBuilder.java:178) at org.eclipse.virgo.osgi.launcher.FrameworkBuilder.start(FrameworkBuilder.java:159) at org.eclipse.virgo.test.framework.OsgiTestRunner.launchOsgi(OsgiTestRunner.java:171) at org.eclipse.virgo.test.framework.OsgiTestRunner.run(OsgiTestRunner.java:84) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:50) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) Caused by: org.eclipse.osgi.service.pluginconversion.PluginConversionException: Could not find a META-INF/MANIFEST.MF, plugin.xml or a fragment.xml in /Users/glynnormington/eclipse/virgo/org.eclipse.virgo.kernel/org.eclipse.virgo.kernel.test/target/org.eclipse.osgi/bundles/41/1/bundlefile. at org.eclipse.core.runtime.internal.adaptor.PluginConverterImpl.fillPluginInfo(PluginConverterImpl.java:114) at org.eclipse.core.runtime.internal.adaptor.PluginConverterImpl.convertManifest(PluginConverterImpl.java:714) at org.eclipse.core.runtime.internal.adaptor.EclipseStorageHook.generateManifest(EclipseStorageHook.java:448) ... 24 more To see the bundle manifest generation failure, open template.mf in org.eclipse.virgo.kernel.artifact under Eclipse and click on the "Update MANIFEST.MF" link in the Overview pane.

Clicking on the Update MANIFEST.MF link now successfully generates a manifest in target/classes as well as updating the manifest created above. However, we need to get to a point where we can do without the manifest in src/main/resources/META-INF as this is confusing and a source of all sorts of issues and it was a great step forward when we were able to delete it (although we didn't realise how precarious running integration tests under Eclipse had become).
