Hi,  
When signing our module we are now getting this error.

```auto
Exception in thread "main" org.apache.commons.cli.UnrecognizedOptionException: Unrecognized option: -jar

```

we have never come across this before, has anyone else?

```

It’s the same sign-module.bat file we’ve ran since the start

You have an extra `-jar module-signer.jar` in the arguments to the module signer itself.

I don't know how that ever ran or why it stopped now.

edit: looking closer it seems you just copy/pasted the command twice?

thank you, that has solved a lot of headache, must have been copied by accident somewhere along the line
