Failure to rename an eclipse plugin (Unable to res

Question

I am working on an eclipse plugin. After some marketing people got in the way, I need to rename my plugin. So I went ahead and opened the plugin.xml in eclipse and changed the name and ID in the overview TAB.

Then, when I try to launch eclipse to see everything is working, it dumps a whole lot of prints about not being able to resolve plugin (I removed the name of the old plugin for IP reasons, sorry):

!ENTRY org.eclipse.jface 4 0 2014-07-02 14:19:08.885

Any idea on how to clean it? I tried the eclipse project clean but it didn't help...

Thanks, Oren

Answer 1

OK, issue solved. I had to do a full workspace clear in the Main tab of the run configuration and the error was gone.

Hope this helps someone :-)

Answer 2

Check the Configuration tab of your Eclipse Application launcher, and make sure you're Clearing the configuration area before launching.

Answer 3

The only thing that worked for me was to remove the workspace folder that Eclipse stores its files in, and then re-opened Eclipse, and had it default to that same path with a clean start. I had opened a new version of Eclipse, which caused my issue. So it was still using the same configuration the previous version had, and was probably a little more complex than changing a single configuration setting.
