This is very early days!
We're just starting to put together some Eclipse tooling, so please be patient - this page is mostly for developers of the tooling
Currently we have an eclipse plugin maven plugin. You can use it as follows
cd tooling/eclipseplugin-plugin maven plugin:install
Then to use it to create an empty plugin distro
cd ../../base maven eclipseplugin:generate
and you'll get the plugin distro.
