This is because some newer Java versions fail to compile the files. The latest nightly build does not have this problem and you can resolve the issue by removing the offending line from omc-java.install (you usually don't need the jar-file and you could use https://github.com/OpenModelica/OMJava instead if you do need it)

Thanks for this information.

The nightly build openmodelica_1.13.0~dev-924-g9375dc8 did build successfully, with pbuilder but there are dependency issues that keep the packages from being installed.

Specifically, the packages omlib-modelicareference and omlib-modelica are required dependencies that are apparently not being built. They don't appear as binary packages to be built in the dsc file.

dpkg: dependency problems prevent configuration of omedit:

 omedit depends on omlib-modelica-3.2.2 | omlib-modelica-3.2.1; however:

  Package omlib-modelica-3.2.2 is not installed.

  Package omlib-modelica-3.2.1 is not installed.

 omedit depends on omlib-modelicareference; however:

  Package omlib-modelicareference is not installed.

You can find the libraries here: https://build.openmodelica.org/apt/pool/libraries/

You can build your own deb-files from https://github.com/OpenModelica/OMLibraries (`make debian` once you setup the locations of the deb-packages and files for apt-ftparchive).
