Hi,

I need to remove a library (jar) from module libraries list, so I do:

 ModuleRootManager rootManager = ModuleRootManager.getInstance(module);

Unfortunatelly the library named libURL (full path to it, prefixed jar://
and suffixed !/) is not removed from its root.

The same library was added calling:
addRoot(libURL, OrderRootType.CLASSES);

Could someone tell me please, what is wrong here?

To remove a library, call LibraryTable.removeLibrary().
To remove a root from library, call Library.ModifiableModel.removeRoot().
Do not forget to commit ModifiableModel afterwards.

Friendly,
Dmitry
