I found in some cases, I needed also to go to the features/ and remove the uninstalled plugins. > * 2nd, go to the top level Eclipse directory, and find the file > artifacts.xml. > Edit this file, finding and removing all stanzas that refer to the artifacts > that were uninstalled. Save this file. Here's a way to use the Eclipse editor to do this. Start Eclipse, open some temp project, add a file "linked to a file in the file system" and link it to the artifacts.xml file. Then, select the file in the Eclipse view, and click on menu -> Search, and use a regular expression search to find the stanzas. Click on replace, give the empty string as the replacement, and click "Preview" - and check the results are what you want. The regular expression can be something like: (?s)<artifact [^>]*?org\.eclipse\.uima*?</artifact> In English, turn on multi-line matching for ".", look for the start of an artifact stanza that has org.eclipse.uima and scan to the first ending </artifact> tag. When I do this, I use another eclipse instance :-) -Marshall > Now, a reinstall works (for me). > > -Marshall Schor > >
