[jdt-dev] Get notified on runtime classpath changes

[Christoph Läubrich <laeubi@xxxxxxxxxxxxxx>]

Is there a way to be notified about any change on the classpath e.g.:

- class file replaced (in this or any related project)
- jar added
- maven dependency updated

I don't really care about the type or source, I just want to update some 
internal state whenever anything changes that could affect a previous 
run of a tool that uses the

String[] classPathEntries = 
JavaRuntime.computeDefaultRuntimeClassPath(javaProject);

to build a classloader so I know i need to refresh this. A 
Resourcelistener and/or builder seem to be covering much more than I 
need and wouldn't be specific enough so I wonder if there is anything I 
could use for this specific case, I assume that JDT already knows when 
something changes here and recompile classes as necessary...
