To build the intellij plugin, you need first to install the libs using the install-libs.sh
script, as the IntelliJ libs are not available on Maven central. Then you should be able
to run mvn package to generate the plugin.
However, if you want to use Forge inside IntelliJ, just install it directly via the Plugin
Manager inside IntellIJ
