I've updated my 3.1_pre1 with 3.1_pre4. No problem while emerging, but when I execute 'eclipse-3.1', I never reach the 'choose your workspace location' window, instead I get an error window : "An error has occured. See the log file ~/.eclipse/org.eclipse.platform_3.1.0/configuration/1113403819814.log". This log says : eclipse.buildId=Gentoo Linux eclipse-sdk-3.1_pre4 java.version=1.4.2_07 java.vendor=Sun Microsystems Inc. BootLoader constants: OS=linux, ARCH=x86, WS=gtk, NL=fr_FR Framework arguments: -Xmx 512M Command-line arguments: -os linux -ws gtk -arch x86 -Xmx 512M !ENTRY org.eclipse.core.runtime 4 2 2005-04-13 16:50:20.507 !MESSAGE Plug-in "org.eclipse.ui.ide" was unable to instantiate class "org.eclipse.ui.internal.ide.IDEWorkbenchPlugin". !STACK 0 java.lang.NoSuchMethodException: org.eclipse.ui.internal.ide.IDEWorkbenchPlugin.<init>(org.eclipse.core.runtime.IPluginDescriptor) When I emerge the 3.1_pre6 version, it works fine. Only thing I've done over the emerge configuration pass : 'chgrp dev' on the plugins and features dirs in /usr/lib/eclipse-3.1. Reproducible: Always Steps to Reproduce: 1. emerge =eclipse-sdk-3.1_pre4 2. launch it 3. Actual Results: A window error which points me to a log which says java.lang.NoSuchMethodException: org.eclipse.ui.internal.ide.IDEWorkbenchPlugin.<init>(org.eclipse.core.runtime.IPluginDescriptor) Expected Results: launching eclipse normally with a window asking for the path to the workspace.
I suggest you try 3.1 final. If that doesn't work for you, please open a fresh bug about it.
