Marshall Schor reopened UIMA-3133:
----------------------------------


search for uimaj-core jar fails in case where this is launched in "development 
mode" - need recursive looking in that case
                
> Eclipse launcher plugin fails if uimaj-core not on project classpath
> --------------------------------------------------------------------

>          Components: Eclipse plugins
>    Affects Versions: 2.4.1SDK

>
> The Launcher launches a small Java class which needs the uimaj-core classes 
> to run.  The Launcher includes the project's classpath, so if uimaj-core is 
> on that classpath, all is well.  But there's no requirement that uimaj-core 
> be on the project's classpath (for example, imagine a project for an 
> aggregate, that just contains xml descriptors, etc.).  In that case, the 
> failure happens.
> The launcher is attempting to handle this by suffixing the uimaj-ep-runtime 
> jar to the launched classpath.  That worked in 2.4.0 and earlier, because 
> that plugin jar had all the uimaj-core classes.  However, as of 2.4.1, we 
> changed the packaging of this, and the uimaj-ep-runtime is now set up to have 
> embedded jar files, with an OSGi Bundle-Classpath which identifies these 
> Jars.  That doesn't help this Jar's usage as just a plain (non-OSGi) Jar.  
> Reported by Peter Klügl who also discovered the fix in project Ruta.  The fix 
> here is slightly faster - only the uimaj-core jar is included (that's all the 
> launcher class needs).
