I installed kubernetes-cli and its dependency kubernetes-credentials on Jenkins 2.32.1 on Java 7, and there are no visible signs of it.

Installing on a more current Jenkins on Java8 worked fine

NOTE: Plugin doc say they should work on Jenkins 2.32.1, which we have, but does not specify the required Java version.

   EXPECTED: Create a job GUI should show a new option to set up a kubernetes environment

   ACTUAL: No

3. Restart Jenkins
4. Verify the plugins
ACTUAL: Still no for everything.
