you should not set the main= but only java -classpath /usr/share/java/picard.jar picard.cmdline.CommandLineParser --version BUT the class has not "main", this is not en entry point for the program, I will try to look. > > > So how can I successfully query for the picard-tools version. > > Kind regards > > Andreas. > > > [1] https://anonscm.debian.org/git/debian-med/metabit.git > > -- > http://fam-tille.de > >
