We have a multi-configuration job that builds a bunch of builds with various configurations. After the job completes, we use parameterized trigger plugin to launch a test with the respective configurations. Screenshot of the multi-configuration project is shows in attachment "Picture 2.png"

The properties file contains 2 lines like this:
BUILDTOTEST=8015
CONFIGURATION=FOOBAR

We upgraded this plugin from version 2.0 to 2.3 and discovered the downstream test job was no longer being triggered. No exceptions in the logs. No explanation in build consoles.

Downgrade back to 2.0 makes the downstream job triggering again.
