Google Plugin for Eclipse Luna?
Solution 1
It turns out there is a way to alter the manifests to allow the Google Plugin for Kepler to install in Eclipse Luna. Contributor Ze Kritter on Google Groups has written an Apache Ant build.xml
file that performs the necessary work, original here and reproduced below.
It worked beautifully for me. I have successfully run this script and installed the plugin into Luna, and - at least for GWT - it seems to work as usual.
According to the discussion thread on Google Groups there are some incompatibilities with the Maven plugin (I personally don't use Maven) and a new and suitably well-tested Google plugin will be coming out shortly (late July 2014).

I'll add the words Eclipse Mars here, so this solution can be found by searching and potentially adapted for the June 2015 release of Eclipse.
Solution 2
According to the Google Plugin for Eclipse community forum, we might be able to expect a new plugin with Luna support by mid-July.

Solution 3
This seems to be recently resolved.
I didn't find the plugin in the Marketplace as of writing this, but there's an update site: https://dl.google.com/eclipse/plugin/4.4
You can read more about this at https://developers.google.com/eclipse/docs/install-eclipse-4.4

I have installed Eclipse Luna 4.4-M6. I tried installing the Google Plugin for Eclipse 4.3 (Kepler), but Eclipse would not allow me to install it.
Is there some way to force it to install (e.g. by downloading it and editing some manifest or other)? Or would this be futile due to breaking changes between 4.3 and 4.4?
-
ᴇʟᴇvᴀтᴇ about 10 yearsI understand that Luna is still in development. I was wondering if there's some way to install the plugin anyway. I'm prepared to take that risk.

ᴇʟᴇvᴀтᴇ almost 10 yearsThanks for pointing out this group. I've managed to install the Kepler plugin in Luna using instructions provided in that discussion thread. I've upvoted you, but marked my answer as the accepted answer as it offers a way to solve the problem that doesn't involve waiting... :-)

ᴇʟᴇvᴀтᴇ almost 10 yearsYep, I actually added a comment to that effect under my answer above, but it's good to have it as a full answer and not just a comment. Thanks.
