What am I supposed to do or uninstall? I think it is another plug in or something that's causing a conflict

I’m using the following version of Eclipse on Mac 10.9.5
Eclipse Java EE IDE for Web Developers.
Version: Juno Service Release 2
Build id: 20130225-0426
When I click on “Help” -> “Check for Updates”, I get the “Available Updates” dialog
The operation cannot be completed. See the details.
Cannot complete the install because one or more required items could not be found.
and there is only a “Cancel” dialog. When I click “Cancel,” a smaller dialog appears with the message
Some sites could not be found. See the error log for more detail.
and when I click the “Details” button, I get
Some sites could not be found. See the error log for more detail.
No repository found at http://download.eclipse.org/mat/1.3.1/update-site/.
Unable to read repository at jar:file:/Users/davea/Downloads/ehep-1.0.0.zip!/site.xml.
error in opening zip file
At this point, I don’t know what else I need to do to successfully install updates or correct the existing problem.
Edit: Following the suggestion, I fixed the broken repositories, however, now when I get the Available Sites dialog, I only check the
Eclipse IDE for Java EE Developers
option, yet I still get these errors, complaining about conflicting dependencies. How do I get around these?

When you open http://download.eclipse.org/mat/1.3.1/update-site/ in a browser, it says that it moved to http://archive.eclipse.org/mat/1.3.1/update-site/. Maybe you can try this.
I haven't tried this, but it seems like you can configure the Update Site location using Window -> Preferences -> Install/Update -> Available Software Sites, and there finding and replacing the above location.
About that other error: Seems like you added some local archive site some time ago and since then deleted or moved that archive. If you still need it, try to restore it, otherwise use the above preferences to remove it.
Having said that, it might be a good idea to move on to a newer version of Eclipse...
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.
