The plugin is not able to receive the parameters when job build is triggered with REST API buildWithParameters.

I tried with syntax:

curl -X POST https://user:token@jenkins_address/job/jobname/buildWithParameters -F parameter=value

And also:

curl -X POST https://user:token@jenkins_address/job/jobname/buildWithParameters?parameter=value

In either case the build starts, but the parameter value is not set.

Could you please check it?

Thanks
