[BUILD PROBLEM] Fail on JPropex build.xml line 122 \\ Error 65280

[Maarten Kesselaers]

My build just crashed on the build.xml under
./main/l10ntools/java/jpropex/ at line 122 :

122                classpathref="classpath">

So I guess I need to set a CLASSPATH, right?
To which directory should it be set?

Thanks for your help,
Regards,
Maarten
