I am using the newest version (2.8.0) of the Eclipse-Groovy plugin that ships with groovy-all-2.1.5.jar. I added Guice to my Groovy project, and when I go to run them from inside Eclipse I get the following error in the console output:

According to this answer it's because ShortTypeHandling wasn't added until 2.3.x. So I would now like to attach groovy-all-2.3.3.jar to my Eclipse project's classpath.

The problem is that I don't seem to have edit permissions to change what library the Groovy Libraries library uses under the hood. And when I manually add the 2.3.3 JAR to my build path, I get the following error:

Caught: java.lang.ExceptionInInitializerError
java.lang.ExceptionInInitializerError
Caused by: groovy.lang.GroovyRuntimeException: Conflicting module versions. Module [groovy-all is loaded in version 2.1.5 and you are trying to load version 2.3.3

What are my options?

Groovy-eclipse versions have its own compilers and are "locked" to them. You may change the versions to whatever is listed under Window > Preferences > Groovy > Compilers, but, AFAIK, you can't change to an arbitrary version of the compiler by simply changing the groovy-all jar in the guts of the plugin dir.

You can install new compiler versions using the update site or eclipse marketplace

Update: install additional compiler versions through Help > Install new Software, select Groovy update site and expand the Extra Groovy Compilers session:

Note i'm using snapshot update site, because i like to live dangerously.
