problem installing eclipse groovy plugin in galileo

Question

I'm trying to install groovy plugin in eclipse 3.5 using this update site.

It does install but when it tries to restart I get an exception.

!SESSION Sat Aug 29 15:47:17 PDT 2009 ------------------------------------------ 
!ENTRY org.eclipse.equinox.launcher 4 0 2009-08-29 15:47:17.287
!MESSAGE Exception launching the Eclipse Platform: 
!STACK java.lang.ClassNotFoundException: org.eclipse.core.runtime.adaptor.EclipseStarter 
  at java.net.URLClassLoader$1.run(URLClassLoader.java:200) 
  at java.security.AccessController.doPrivileged(Native Method) 

I tried to start using -clean options,deleted workspace no luck

Did anyone get this too??

Answer 1

I had the same problem with installing the CVS plugin on a Eclipse Platform installation running TeXlipse. Turns out, after installing CVS, the installer had modified not the osgi.bundles, but the osgi.framework.

/Applications/TeXlipse/configuration/config.ini said:

 osgi.framework=file\:/Applications/TeXlipse/Eclipse.app/Contents/MacOS/plugins/org.eclipse.osgi_3.5.2.R35x_v20100126.jar

and it was supposed to say

 osgi.framework=file\:/Applications/TeXlipse/plugins/org.eclipse.osgi_3.5.2.R35x_v20100126.jar

Answer 2

OK now finally i fixed it after 2 days of war with eclipse, so for some reason when groovy plugin was installed eclipse modified config.ini file inside configuration folder so I have to modify config.ini file to replace osgi.bundles value with

osgi.bundles=reference\:file\:org.eclipse.equinox.simpleconfigurator_1.0.100.v20090520-1905.jar@1\:start,reference\:file\:plugins/org.eclipse.jdt.core_3.5.0.xx-20090828-1900-e35.jar@4,reference\:file\:/Applications/galileo/plugins/org.apache.commons.collections_3.2.1.jar@4,reference\:file\:/Applications/galileo/plugins/org.apache.commons.lang_2.3.0.v200803061910.jar@4,reference\:file\:/Applications/galileo/plugins/org.codehaus.groovy_1.7.0.xx-20090828-1900-e35/@4,reference\:file\:/Applications/galileo/plugins/org.codehaus.groovy.eclipse.ant_2.0.0.xx-20090828-1900-e35/@4,reference\:file\:/Applications/galileo/plugins/org.codehaus.groovy.eclipse.codeassist.completion_2.0.0.xx-20090828-1900-e35.jar@4,reference\:file\:/Applications/galileo/plugins/org.codehaus.groovy.eclipse.codebrowsing_2.0.0.xx-20090828-1900-e35.jar@4,reference\:file\:/Applications/galileo/plugins/org.codehaus.groovy.eclipse.core_2.0.0.xx-20090828-1900-e35.jar@4,reference\:file\:/Applications/galileo/plugins/org.codehaus.groovy.eclipse.core.help_2.0.0.xx-20090828-1900-e35/@4,reference\:file\:/Applications/galileo/plugins/org.codehaus.groovy.eclipse.cstviewer_2.0.0.xx-20090828-1900-e35.jar@4,reference\:file\:/Applications/galileo/plugins/org.codehaus.groovy.eclipse.refactoring_2.0.0.xx-20090828-1900-e35.jar@4,reference\:file\:/Applications/galileo/plugins/org.codehaus.groovy.eclipse.ui_2.0.0.xx-20090828-1900-e35.jar@4,reference\:file\:/Applications/galileo/plugins/org.eclipse.jdt.groovy.core_1.0.0.xx-20090828-1900-e35.jar@4

By default osgi.bundles value is osgi.bundles=reference\:file\:org.eclipse.equinox.simpleconfigurator_1.0.100.v20090520-1905.jar@1\:start but as soon as I installed groovy plugin I had a modified value which caused eclipse fali to start.

now my eclipse starts and i see the groovy features too..

It looks like you're missing a class or a jar required by the plugin; I'm not sure which one though, since the stacktrace does not indicate any such plugin specific class. You could attempt the following:

1. Examine the .log file of the workspace to view any additional details of the exception.
2. Verify if all the Groovy Eclipse plugin jars are present in the plugins and features directory of the Eclipse installation.
3. Start Eclipse with the consolelog and debug switches, and pipe the output to a debug log file. Examine for anything indicative of the problem in the logfile; if needed post the log file. The command to start Eclipse in this mode would be

   $eclipse -consolelog -debug | tee debugfile.log

4. Install the plugin on a clean installation of Eclipse.
