How to reinstall an Eclipse plugin after its modification?

Sorry for the question but I'm at the end of my wits. I'm very far from Eclipse plugin development and Java in general.

Eclipse version - Juno.

I needed to customize DSF-GDB plugin of Eclipse-CDT. I downloaded CDT sources, created a PDE project, imported there org.eclipse.cdt.dsf.gdb plugin, fixed configuration errors so that the project could be built. I did my change (removal of one baneful line) Then I exported my plugin via Export...->Deployable Plug-ins and Features and got my JAR file.

I've seen a couple of questions at StackOverflow regarding installation of such plugins so I put my JAR file under dropins folder. But it seems it hadn't been included for I didn't observe it neither under About Eclipse SDK->Installation Details->Plugins nor under Preferred Launchers (there was only the old one).

I thought probably it was because there could not be two instances of the plugin at the same time. So I tried to remove the original one from under plugins directory. It didn't help though, DSF-GDB integration disappeared completely.

How do I install my plugin properly?

Well, I've managed to do this. Thanks to @Chris Gerken for suggesting the direction of investigation.

First I tried to follow the advice of Chris but it didn't help. Then I decided to approach from other side and reinstall the plugin with p2 platform. I used my plugin project, created a new feature project and an update site project so that I could select it in p2 dialog box. I failed to install the plugin in this way because p2 said that two versions of the same plugin could not be present at the same time. I wonder why didn't it offer me to choose between the one I wanted to install and the other that already had been?

Anyway I abandoned it and decided again to ask google. I came across this wiki page and learnt that there existed a wonderful file called bundles.info. It contains the whole list of plugins in plugin/ directory which should be picked up. I found there my plugin, changed its version, copied JAR file into plugin/ directory and ran eclipse -clean. And voilà tout! Eclipse started to work with my plugin.

Eclipse knows the current version of each installed plugin and will sometimes not make changes if a plugin is re-installed with the same plugin version or if the version changes but only minor metadata has changed.

So try:

  • Increment the version number of the plugin
  • Re-install by putting it in dropins
  • Restart Eclipse with the -clean option
