That worked just fine

I have moved most of the helpers to javatools[1], where they are now
available. I will be adding more and probably changing the interface to
them as well as I get more experience with writing these tools and using

However, the most important tool is building these plugins is
"pde-build" (upstream refers to it as pdebuild, but that named clashed
with a pbuilder tool, so we have renamed it). This script is (together
with a helper) generated during the build of eclipse.

Sadly our current master branch[2] is broken by some regressions when we
switched to the 3.5.2 branch. You can however build eclipse using
pkg-java's mini-install[3] - the 3.5.1 sources are there (depending on
your arch it may even be precompiled for you). You will need
libmortbay-java and libjasper-java to build and install it (they are
built and available from the arch all part).

That version of eclipse probably do not ship with pde-build (and if it
does, it is still by its old name). To this end I have created a little
tar.gz that can generate pde-build from an installed eclipse [4]. I am
not sure that pde-build is compatible with eclipse 3.4; you are welcome
to try of course.

To generate pde-build, just run (requires that eclipse-pde is installed):
 $ make
 $ sudo make install
