Definitely requires more than just a compiler - but I think publicity and broad developer support is even more important that IDE plug-ins and libraries. Java already has extensive libraries, so it is probably possible to leverage these. Also, a lot of languages gain some popularity before plugins start appearing. But completely agree - a compiler is not enough...
