set jenkins environment variable in pipeline

Question

I am trying to set a Jenkins environment variable where I can get html values and pass it downstream for filtering in parameters stage. I am unable to do so, here we have minimal example

pipeline { agent any environment { get = new URL("http://company_server:port/packages/").openConnection(); getRC = get.getInputStream().getText() // set getRC and access this value for result (highlited with ***********) } stages { stage('Parameters'){ steps { script { properties([ parameters([ [$class: 'ChoiceParameter', choiceType: 'PT_SINGLE_SELECT', description: '', name: 'foo', filterLength: 1, filterable: true, script: [$class: 'GroovyScript', fallbackScript: [ classpath: [], sandbox: false, script: "return['']" ], script: [ classpath: [], sandbox: false, script: ''' def result = (getRC =~ /(">)pip_pkgs[^<]*/).findAll() def sublist = [] result.each { sublist.add(it[0].split(",")[0].replace('">', '')) } return sublist ''' ] ] ], ]) ]) } } } } }

The environment block is for setting shell environment variables. You appear to want to set global Groovy Pipeline variables instead. If you migrate the variables, then it should start functioning correctly. — Matthew Schuchard

check here : jenkins environment variables

stages { stage('Build') { steps { echo "Database engine is ${DB_ENGINE}" echo "DISABLE_AUTH is ${DISABLE_AUTH}" sh 'printenv' } }

When you are using a variable that was set as an environment variable, you have to use like this: ${your_variable} (See Using environment variables)

In your case:

pipeline { agent any environment { get = new URL("http://company_server:port/packages/").openConnection(); getRC = get.getInputStream().getText() // set getRC and access this value for result (highlited with ***********) } stages { stage('Parameters'){ steps { script { properties([ parameters([ [$class: 'ChoiceParameter', choiceType: 'PT_SINGLE_SELECT', description: '', name: 'foo', filterLength: 1, filterable: true, script: [$class: 'GroovyScript', fallbackScript: [ classpath: [], sandbox: false, script: "return['']" ], script: [ classpath: [], sandbox: false, script: ''' def result = (${getRC} =~ /(">)pip_pkgs[^<]*/).findAll() def sublist = [] result.each { sublist.add(it[0].split(",")[0].replace('">', '')) } return sublist ''' ] ] ], ]) ]) } } } } }
