Moving a bndrun file causes an IllegalArgumentException when trying to run it

[jpchristen]

I accidentally created a bndrun file in a package. After I moved it to the right place in the project via drag & drop and tried to run it, the following error occurs:

Status ERROR: bndtools.core code=0 Error initialising bnd launcher java.lang.IllegalArgumentException: Bnd launch target was not specified, or does not exist.
java.lang.IllegalArgumentException: Bnd launch target was not specified, or does not exist.

It is still possible to run the file if you start via Run As..., but I think this is very obscure.
