Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

Running plm from a bash shell, straight after installation, fails with an error message and a backtrace when the user has a gpg.format option in his global .gitconfig.

org.eclipse.jgit also chokes on commit.gpgsign and tag.gpgsign. Commenting these options allows for a clean trace (except the warning about slf4j)

#[gpg]
#	format = ssh
#[commit]
#	gpgsign = true
#[tag]
#	gpgsign = true

I have not found a way to direct org.eclipse.jgit to a local gitconfig file and ignore the user's global config file.

Backtrace as kindly requested

reassign 1132766 jgit

tag 1132766 fixed-upstream
thanks

Salut David,

thanks for the report, and for testing the PLM :)

The bug you are suffering seems to be due to jgit, not to the PLM directly. It
seems to be reported upstream as https://github.com/eclipse-jgit/jgit/issues/44
which was fixed (apparently), and merged in jgit v7.1. Unfortunately, jgit in
Debian is somewhat behind for the moment. So I guess we have to live with the
issue for a little while. Another solution is to drop a jgit jarfile in the
directory from which you start the PLM.

Happy hacking,
Mt
