Error in eclipse project grails/groovy

Question

I have the following error when working with grails project in eclipse

An internal error occurred during: "Requesting Java AST from selection". org.codehaus.groovy.eclipse.core.compiler.GroovySnippetCompiler.(Lorg/codehaus/groovy/eclipse/core/model/GroovyProjectFacade;)V

Anybody have the same problem?

How fix the problem?

Answer 1

Update :

The issue was fixed in the latest Snapshot releases of Groovy Eclipse 2.9.3 so you may now just follow the guide @ https://technology.first8.nl/eclipse-neon-grails-2-x-with-groovy-and-gsp-support/

Previous answer :

I also stumbled across this error and it happens only in classes that are grails-artefacts (services, controllers, ...). It seems to be related to recent changes in grails-eclipse plugin 2.9.2. A version from june 2017 worked without any issues and a recent upgrade to 2.9.2 release from january 2018 brought up the issue.

I fixed the issue by using the groovy-eclipse 2.9.2 version from 2015 which is contained in the GGTS update-site zip ( http://download.springsource.com/release/TOOLS/update/3.6.4.RELEASE/e4.5/springsource-tool-suite-3.6.4.RELEASE-e4.5-updatesite.zip ).

What I was searching for (without success) was an archive of release versions of the groovy-eclipse 2.9.2 branch. This way I would at least have the option to install the working 2.9.2 version from june 2017... If anyone has a clue where to find older versions I would be happy for a hint!

The stacktrace of the initially mentioned Exception looks like that:
