JDK Parameter

Adds a build parameter that allows selecting a configured JDK installation for each build.

This plugin adds a build parameter that allows setting which JDK should be used for a job on a per-build basis.

The JDKs available for selection can be configured on the job configuration page when the JDK parameter is enabled.

1. Go to Manage Jenkins → Global Tool Configuration
2. Configure one or more JDK installations
3. Save the configuration

To use in a job:

1. Open the job configuration page
2. Enable This build is parameterized
3. Add parameter → Select JDK Parameter
4. Choose the default JDK and allowed JDK selections

On the build parameters page, a dropdown list allows selecting which configured JDK should be used for that build.
