java <classNameToRun> $urlValue

Thanks for the suggestions, but it worked when i did the following: I hit the

JENKINS_HOST_URL/job/JENKINS_SEED_JOB_NAME/api/json?pretty=true

and found the current build number, thereafter, hitting jenkins again with this number(JENKINS_HOST_URL/job/JENKINS_SEED_JOB_NAME/currBuildNum/api/json?pretty=true),

I was able to fetch all the parameters passed in there in this build.

Probably your most reliable approach is to explicitly pass parameters as system properties in your Jenkins configuration, eg -DREPOS=${REPOS}
