Can't start gitblit in windows --- java.lang.NoClassDefFoundError: org/kohsuke/args4j/CmdLineException

HI
I am using below command to start gitblit.
java -jar gitblit-1.8.0.jar --baseFolder data.

But this is failing with below error.

I have java 10 installed on my windows desktop. I have set the path and classpath variable in environment variables.

I have the same problem, and I have consult a lot of data , but not get a effective idea.

I'm not sure where you got the gitblit-1.8.0.jar file, but that jar is just part of a whole distribution package, like GitblitGO, to be used together. Information about the Gitblit GO package is here at the gitblit.com site.

Even when you get GitblitGO and set it up correctly as per instruction, gitblit only supports Java 7 and 8 runtimes. For Java 9+, you'll get exceptions similar to the above.

A workaround to make it run with Java 9+ is to modify the gitblit.cmd file and change it from:

@java -jar gitblit.jar --baseFolder data %*

to

@java -cp gitblit.jar;"%CD%\ext\*" com.gitblit.GitBlitServer --baseFolder data %*

and then start up the Gitblit server by executing the modified gitblit.cmd file.
