We recently upgraded our Jenkins (2.361.1) and all Plugins to the latest versions. It had been around 2 years since Jenkins update and I did not keep track of the Artifactory plugin version. The Artifactory plugin is now to version to 3.17.0 and first started experiencing this issue. I noticed there was a newer release and went to 3.17.1 today.

When the shared library tries running "buildInfo.env.collect()", there is a null pointer error, on this call: https://github.com/jenkinsci/artifactory-plugin/blob/9c6002534e39154948cfb1c120b056580ebc93e5/src/main/java/org/jfrog/hudson/pipeline/common/executors/CollectEnvExecutor.java#L31

I believe this is a bug in the plugin code.
