[Debian-med-packaging] Bug#842815: Help needed for change of build system to gradle of package libsis-jhdf5-java

[Andreas Tille]

Hi,

upstream of libsis-jhdf5-java[1] has switched to gradle in its new
version that is compatible with HDF5 1.10.  I tried to adapt debian/rules
from previous manual build to buildsystem=gradle but got:

...

Since I had no idea how to fix this I simply tried to remove this
dependency definition (ant is installed as Build-Dependency anyway) and
thus I tried the following quilt patch:


$ git diff
diff --git a/debian/patches/fix_build_dir.patch b/debian/patches/fix_build_dir.patch

This leads to:

I wonder how I could deal with these classpath definitions in the gradle
input.  Or would you suggest to rather stick to manual build as it was
done before?

Kind regards

       Andreas.
