Disable Eclipse plugins?

Question

I'm running latest version of Eclipse (Indigo) for Java Development. By default it comes with a bunch of plugins we don't need or want. How do I disable or uninstall them? The uninstall button is greyed out in 'About->Installation details'

For example, I wish to disable these:

Maven

GIT

Usage

We use Ant and Perforce, so no reason to have these.

In the Maven and the Usage, it keeps 'updating indexes' in background which is killing the bandwidth here. Even though we disabled all the downloading in the preference (Usage respects this, but it seems Maven is just ignoring the settings). For GIT, it seems buggy and is throwing errors on startup; even after a clean/fresh install.

Again, we don't use or want these. They cause nothing but problems and we're better off with out them, how to get rid of them?

Solution

To uninstall them just go to Help->Software Updates... got to the Installed Software tab ('What is already installed' link in newer versions) and uninstall the ones you don't need.

Edit: Just saw you mentioning that they are greyed out... This might be a bit more dangerous but you could just try deleting them from eclipse/features and then from eclipse/plugins.

Edit2: Another option is preferences->General->Startup and Shutdown and unselect them.
