Upgrade groovy-eclipse to the Eclipse Java 7 compiler

Mauro Molinari added a comment - 26/Sep/11 9:38 AM - edited Issue GRECLIPSE-1177 is marked as a duplicate of this. I'm using Indigo SR-1 (3.7.1) with GRECLIPSE 2.5.2.xx-20110921-1600-e37 downloaded from http://dist.springsource.org/release/GRECLIPSE/e3.7/ and whenever I try to open a Groovy file I have the following exception and the editor does not show: java.lang.NoClassDefFoundError: org/codehaus/groovy/eclipse/refactoring/formatter/GroovyIndentationService at org.codehaus.groovy.eclipse.editor.GroovyAutoIndentStrategy.<init>(GroovyAutoIndentStrategy.java:50) at org.codehaus.groovy.eclipse.editor.GroovyConfiguration.getAutoEditStrategies(GroovyConfiguration.java:172) at org.eclipse.jface.text.source.SourceViewer.configure(SourceViewer.java:502) at org.eclipse.jdt.internal.ui.javaeditor.JavaSourceViewer.configure(JavaSourceViewer.java:230) at org.eclipse.ui.texteditor.AbstractTextEditor.createPartControl(AbstractTextEditor.java:3407) at org.eclipse.ui.texteditor.StatusTextEditor.createPartControl(StatusTextEditor.java:54) at org.eclipse.ui.texteditor.AbstractDecoratedTextEditor.createPartControl(AbstractDecoratedTextEditor.java:440) at org.eclipse.jdt.internal.ui.javaeditor.JavaEditor.createPartControl(JavaEditor.java:3098) at org.eclipse.jdt.internal.ui.javaeditor.CompilationUnitEditor.createPartControl(CompilationUnitEditor.java:1505) at org.codehaus.groovy.eclipse.editor.GroovyEditor.createPartControl(GroovyEditor.java:960) at org.eclipse.ui.internal.EditorReference.createPartHelper(EditorReference.java:670) at org.eclipse.ui.internal.EditorReference.createPart(EditorReference.java:465) at org.eclipse.ui.internal.WorkbenchPartReference.getPart(WorkbenchPartReference.java:595) at org.eclipse.ui.internal.EditorReference.getEditor(EditorReference.java:289) at org.eclipse.ui.internal.EditorManager.findEditor(EditorManager.java:424) at org.eclipse.ui.internal.EditorManager.findEditor(EditorManager.java:402) at org.eclipse.ui.internal.WorkbenchPage.findEditor(WorkbenchPage.java:2178) at org.eclipse.jdt.internal.ui.javaeditor.EditorUtility.isOpenInEditor(EditorUtility.java:130) at org.eclipse.jdt.internal.ui.navigator.JavaFileLinkHelper.activateEditor(JavaFileLinkHelper.java:38) at org.eclipse.ui.internal.navigator.actions.LinkEditorAction$2.run(LinkEditorAction.java:78) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.ui.internal.navigator.actions.LinkEditorAction$1.runInUIThread(LinkEditorAction.java:76) at org.eclipse.ui.progress.UIJob$1.run(UIJob.java:95) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:135) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:4140) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3757) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2696) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2660) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2494) at org.eclipse.ui.internal.Workbench$7.run(Workbench.java:674) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:667) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:123) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:196) 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:344) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:622) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:577) at org.eclipse.equinox.launcher.Main.run(Main.java:1410) at org.eclipse.equinox.launcher.Main.main(Main.java:1386) I'm blocked. Please note that I'm NOT using Java 7, I'm working on a project which is using Java 6. What should I do?

Andy Clement added a comment - 26/Sep/11 10:27 AM You need a dev build from Friday 23rd or later. Only those are installable on Eclipse 3.7.1. It doesnt matter whether you are using java6 or java7, only those versions (or later) of groovy-eclipse are compatible with Eclipse 3.7.1
