Unable to Install Grails Support Due to Dependency Conflict

You have the Object Team Development Tools installed in your workspace. Due to the way that OTDT and Groovy-Eclipse plugin to the Eclipse Java compiler, it is not possible to have both installed at the same time.

Furthermore, it looks like you have installed STS in a read-only location (or in C:\Program Files). Your installation must be moved to a writable location before you can install groovy-eclipse.

I've searched for the OTDT installation on my eclipse, but wasn't able to find it. Do you have any suggestions on how I can find and remove it? Also, did you mean "Grails" when you wrote "Groovy-Eclipse plugin"?

Hmmm...OTDT may have been a red herring. Maybe it is not installed, but p2 (ie- the install manager) is trying to satisfy dependencies and is seeing if installing OTDT will help with the install, but it doesn't.

No, I meant groovy-eclipse, which is a prerequisite for grails tooling. I think the root cause of your problem is being installed in a read-only location.
