Modisco installation [message #687908]

Hi...

I am trying to install modisco on eclipse 3.6 for hours and hours... and the nervous breakdown is closer and closer...

I had to give up the 0.9 version, since it requires com.ibm.icu.4.4.2... (Is it a really mandatory required dependency, or would it be possible to relax the constraint ?)

So I tried the 0.8.2, but there is always something missing or incompatible...

Did someone succeed in installing Modisco on a 3.6 eclipse ?
If yes, how ?

Hi Romain,

the fact is that MoDisco 0.9.0 has Eclipse 3.7 prerequisites.
0.8.2 works with Eclipse 3.6. But the update install may fail depending on other Eclipse components already installed in your Eclipse. What are the messages errors when you try from update site ?

A simple way to have MoDisco (0.8.2 or 0.9.0) is :
- download Eclipse Moddeling bundle (3.6.2 or 3.7.0)
- start it and open "Install Modeling Components" from the toolbar
- select MoDisco in the components

Find a complete install page : http://wiki.eclipse.org/MoDisco/Installation

I finally succeeded in installing the 0.9 version on a fresh 3.7 eclipse version... but still failed on the 3.6...
Anyway, thank you for your answer...

I have now problems with discovering the commons-math last version (using last sources from the svn repository):
- a "java.lang.ClassCastException: org.eclipse.gmt.modisco.java.emf.impl.AnnotationTypeMemberDeclarationImpl cannot be cast to org.eclipse.gmt.modisco.java.AbstractMethodDeclaration"
- and a "java.lang.NullPointerException at org.eclipse.modisco.java.discoverer.internal.io.java.MethodRedefinitionManager.getRawSignature(MethodRedefinitionManager.java:108)" that terminates the discovery process...

I checked the option "LOG_JAVA_ANALYSIS_WARNINGS", but no log file is generated...
Is there another way to find out on which place the NullPointerException occurs (some kind of debug option ?) ?

Thanks for your help,
Regards

Hi Romain,

I could reproduce the issue you describe.
I've filed a bug : https://bugs.eclipse.org/bugs/show_bug.cgi?id=351590
We will investigate this problem.

You can see the stacktrace by double-clicking on the error message in the Error Log view in Eclipse, or in "<workspace>/.metadata/.log"
