Hello, this is blocker problem for us. We upgrade jenkins to 2.7.4 and now we have problem with parameters (https://issues.jenkins-ci.org/browse/JENKINS-36124). But this build 1.22 doesn't works! What can I do? Is possible downgrade jenkins from 2.7.4 back to 1.651.1?

EDIT:
I found temporary solution.
I define all parameters to jenkins configuration -Dhudson.model.ParametersAction.safeParameters=$PARAMS

$PARAMS I find via this command:

for f in `find . -maxdepth 2 -name config.xml`; do (grep -i -a2 'ParameterDefinition' "$f" | grep name); done | cut -d '>' -f2 | cut -d '<' -f1 | sort | uniq

Alternative to defining all parameters individually (which will be harder to find when also using custom predefined parameters on sub-jobs) is to re-enable the old "policy"...

Add -Dhudson.model.ParametersAction.keepUndefinedParameters=true to the JAVA_ARGS in /etc/default/jenkins.

Tested on Jenkins 2.22 with Multijob plugin 1.21.

I was having the same problem with Jenkins 2.19 with Multijob plugin 1.22. It's now working after downgrading the plugin to version 1.21.

This is JENKINS-37300. I believe multijob removed the unsupported EZ templates code to solve that. Suggest this is closeable.
