Error in Repast Simphony Project auto generation

Question

I have just installed Groovy and Repast Simphony in my Eclipse and created a Repast Simphony Project. In the auto-generated files is an error. In the ModelInitializer class, the import:

import static repast.simphony.essentials.RepastEssentials.* 

throws an error: Groovy:unable to resolve class repast.simphony.essentials.RepastEssentials

(I checked the filesystem and the file exists at the given location)

When I remove the static keyword, the error is gone, but the second error "Groovy:class ProbeID is not an annotation in @ProbeID" (this is the annotation at the toString()-method) is still there.

I'm running Eclipse on my Windows 7 machine, Version: Luna Service Release 2 (4.4.2) Build id: 20150219-0600 Java: 1.8.0_31

I have installed in eclipse (for Repast):

• Groovy Compiler 2.3 Feature (2.9.1.xx)
• JDT Core patch for Groovy-Eclipse plugin on Eclipse 4.4 (2.9.1.xx)
• Repast Simphony 2.3.1

Any ideas what might cause the problem and how to resolve it?

Thanks in advance, Frank

Answer 1

The problem was, that Repast Simphony doesn't run with Eclipse 4.4.2. You have to use Eclipse 4.2 when you want to use Repast Simphony.

Answer 2

If I understand you have installed repast Simphony and eclipse separately. Why don't you download directly the Repast Simphony package which comes with groovy compiler, eclipse and all?
