Hi Srirama,
Sorry. My comments only concerned the SVN version (as the plugins should work in the standalone version).
There are two ways to achieve this with the SVN version:
1) In the navigator, create a new feature project (File > New… > Other… > Plug-in Development > Feature Project) and name it as you want (« MyPlugins »).
2) Click next and choose « Initialize from the plug-ins list »
3) Select all the required plugins that compose GIT, CVSEdit, in the list below.
4) Click Finish
5) Open the product you’re using ("gama1.6.1.feature_based_Eclipse3_8_2_release.product", right ?), go the Dependencies tab and click « Add… »
6) Select your new feature from the list
7) On the Overview tab, click on « Synchronize this configuration.. »
8) Then click on « Launch an Eclipse application »
Second way is more straightforward but I dont have these plugins installed so I dont know if it can work. It simply involves doing steps 5 to 8 (not the first ones) but, instead of selecting your new feature (which you havent created), you should select the features that contain GIT and CVSEdit (since they are updatable plugins, they should be based on features).
Is it clearer ?
Cheers
Alexis
