      I have a multibranch pipeline project, where I want to use string parameters, that I don't always need.

      When the build is triggered by a push to git, I get an error with the following stacktrace:

       java.lang.IllegalArgumentException: Null value not allowed as an environment variable: ReleaseVersion

      The pipeline declaration used: 

      properties([
        parameters([
                string(name: 'ReleaseVersion', defaultValue: '', required:false),
                string(name: 'DevelopmentVersion', defaultValue: '', required:false)
        ])
])
library 'tsc-pipelines@master'

echo "|${params.ReleaseVersion}|${params.DevelopmentVersion}|"

      I obviously want to use methods from the "library" that I include, it's just a debug pipeline code. If I delete the library inclusion part, the code runs.

      The code below also produces a similar error:

      properties([
        parameters([
                string(name: 'ReleaseVersion', defaultValue: '', required:false),
                string(name: 'DevelopmentVersion', defaultValue: '', required:false)
        ])
])

pipeline {
    agent any
    stages {
        stage('asd') {
            steps{
                sh "echo ${params.ReleaseVersion}"
            }
        }
    }
}

      -------------

      The following code also produces a similar error: 

      pipeline {
    parameters {
        string(name: 'ReleaseVersion', defaultValue: 'asd')
        string(name: 'DevelopmentVersion', defaultValue: 'asd')
    }
    agent any
    stages {
        stage('asd') {
            steps{
                sh "echo ${params.ReleaseVersion}"
            }
        }
    }
}
