Hello ALL, So after hours of struggling I got a manual installation and a port installation for eclipse 4.32 on FreeBSD working. Maybe not everything is the best solution, but at the end it worked (in a jail) - till the installation.
For more detail please have a look on my gtihub repository - there is more description https://github.com/NorbertXYZ/eclipse/ It would be nice to get an answer what to do next? Maybe I would take the maintainership of the "old" eclipse port, which is "only" version 4.24... All the best from Germany, Norbert -- I love penguins at the south pole, windows in my house and apples on my tree, but not in my computer :)
