[ome-users] OMERO failing to build - java.lang.ClassNotFoundException: org.apache.tools.ant.util.regexp.Jdk14RegexpMatcher

[Renato Alves]

Hi Bernhard,

Well I though to myself, but reading on the documentation, I couldn't
find the folders mentioned there. For instance the
omero_folder/lib/python folder doesn't exist neither does
omero_folder/dist/lib/python. There is also
omero_folder/components/tools/OmeroPy/src/omero but it fails to import
when searching for one file that is missing.
I assumed the missing files were generated using the build-py target,
hence my attempt to build it.

With the suggestion from Mark Woodbridge I managed to progress in the
compilation, but now I'm getting Memory errors related to garbage
collecting. We've dealt with this error before so we are working on it
and trying to find the relevant docs.

In the meantime thanks for the help.
Renato
