Can I use NetBeans plug-ins in IntelliJ IDEA?
Unfortunately no, NetBeans APIs are different from IDEA’s APIs, so you can’t use .nbms in IDEA. However a lot of functionality that is available for NetBeans as plug-ins is already available out of the box in IntelliJ IDEA. There is also a very healthy community of plug-in writers for IntelliJ IDEA, so check out available plug-ins, they may provide similar functionality as your favorite NetBeans plug-ins.
