[kepler-dev] ant run fails with NoClassDefFoundError ... ModulesTxtReader

[Christopher Brooks]

Hi Jianwu,

Hmm, a clean check out with:
   mkdir kepler
   cd kepler
   svn co 
https://code.kepler-project.org/code/kepler/trunk/modules/build-area
   cd build-area
   ant change-to -Dsuite=kepler
   ant run

fails for me as below. I just did it again to be sure.
Interestingly, the ant change-to -Dsuite=kepler has this message

change-to:
[change-to] java.io.FileNotFoundException:

Interestingly, 
./build-area/src/org/kepler/build/modules/ModulesTxtReader.java
exists.  My guess is that it is not getting compiled.

Could you try finding and removing any ModulesTxtReader.class files?
