This is a complex one. There is some sort of incompatibility between the versions of software you are trying to install. I'm guessing that twig is not compatible with the latest version of Aptana. See if you can get a more recent version of twig (even try a development build).

What am I supposed to do or uninstall? I think it is another plug in or something that's causing a conflict
I downloaded the Eclipse directly from eclipse downloads page - the Eclipse IDE for Java EE Developers and unzipped it
however, when I open .groovy file, its not highlighted. I tried to download and run Groovy plugin from this page
During installing, the eclipse tells me, that groovy is already installed:

But the code is still not highlighted... Can you tell me what next steps should I try to get the code highlighted?
The most likely cause for this is that you are editing your groovy file in a Java editor.
Reopening the groovy file fixed it for me.

Please help me...
I too faced this issue. I could resolve the issue by first updating the Eclipse (Help --> Check for Updates) and then install the jboss tools.
Have you tried using the JDK 6? I had the same problem with JBoss 7, Indigo and JDK 7. Switching back to JDK 6 and wiping out all my other JDK instances worked for me. Make sure that you update indigo (as admin or root) as well.
Hope that helps a little.
I'd like to try UML2 Tools for Eclipse, as shown in this tutorial.
I currently have Eclipse 3.6 Helios for Java EE developers.
In my Eclipse Marketplace I switched marketplace catalog to Yoxos Marketplace and there searched for UML2 Tools SDK(Incubation). When I try to install them, Eclipse wont proceed and complains about some conflicting dependencies. Here's whole trace:
Cannot complete the install because of a conflicting dependency.

Maybe I don't understand whole concept and am trying something inappropriate, I don't know. Thank you for advices.
UML2 Tools has no release that works with Eclipse 3.6 and newer. You could use Papyrus instead.
If you really need UML2 Tools 0.9.0 to work in Eclipse Helios 3.6, there is a workaround you need to do before installing UML2 Tools as explained in this answer.
