Any current version
When setting an environment variable equal to a blank string it comes back a the literal string of `null` instead of being a blank string
Steps to reproduce:
- Create a new pipeline job with the following definition:
pipeline { agent any environment { VERSION_SUFFIX = '' } stages { stage("test") { steps{ echo "env.VERSION_SUFFIX = ${env.VERSION_SUFFIX}" } } } }
- Run said pipeline
- Observe the output is `
env.VERSION_SUFFIX = null
Expected result:
Normally I would expect it to just be a blank string or nothing there
Is it related to this? https://github.com/jenkinsci/pipeline-model-definition-plugin/blob/7502d14aa4db891302abf48a2c7de7c9ced97f95/pipeline-model-definition/src/main/groovy/org/jenkinsci/plugins/pipeline/modeldefinition/model/Environment.groovy#L124
I know that is resolving the env variable but I did not think groovy/java would think a blank string is the same as null so I was confused
