Cannot complete the install because of a conflicting dependency.To recover from the error, I just uninstalled the version of JDT that was conflicting. To do this, click on Help -> Install New Software and click on the "What is already installed?" link at the bottom of the dialog. You can easily locate the old JDT and uninstall it.
Software being installed: Groovy-Eclipse Feature 2.0.0.xx-20091211-1000-e35 (org.codehaus.groovy.eclipse.feature.feature.group 2.0.0.xx-20091211-1000-e35)
Only one of the following can be installed at once:
JDT Core patch for Groovy-Eclipse plugin 2.0.0.xx-20091017-2200-e35 (org.codehaus.groovy.jdt.patch.feature.jar 2.0.0.xx-20091017-2200-e35)
JDT Core patch for Groovy-Eclipse plugin 2.0.0.xx-20091211-1000-e35 (org.codehaus.groovy.jdt.patch.feature.jar 2.0.0.xx-20091211-1000-e35)
... and a lot more ...
