Issue

• Submit a parameterized build request using CURL that used the default parameter values

Environment

• CloudBees Jenkins Enterprise

Resolution

According with the documentation https://wiki.jenkins-ci.org/display/JENKINS/Parameterized+Build

A build can be started just by POSTing to
http://server/job/myjob/buildWithParameters?PARAMETER=Value

So, you can also just launch http://server/job/myjob/buildWithParameters. In this case, the default values are used.
