You are running this on z/OS. I guess you may have followed Henri Kuiper's HowTo? Maybe you are using a different JVM than he did?

lbdyck commented 3 years ago

I followed Henri's instructions. I've tried Java 7, 7.1, and 8.0 - both 31 and 64-bit versions. I have sent Henri an e-mail :)

@lbdyck lbdyck

The java.lang.ClassNotFoundException: org.kohsuke.args4j.CmdLineException happens if You start it like You did. It seems, that jar file is missing to point at least that dependency. I can duplicate it on Windows with exactly that kind of obvious command.

The command from gitblit.sh / gitblit.cmd scripts works fine java -cp "gitblit.jar:ext/*" com.gitblit.GitBlitServer --baseFolder data

Make sure gitblit-1.9.1\ext\args4j-2.0.29.jar is exist
