    Description

      When a more complex expression (in this case contains collect() with closure) is used within the environment directive to set an environment variable, evaluation of the expression fails and an exception is thrown.

      e.g. consider the following pipeline:

       

       
      def myMap = ['1': 'one', '2': 'two']
      pipeline {
          agent none
          stages {
              stage('stage 1') {
                  environment {
                      MY_VAR="${myMap.collect {key, value -> "$key=$value"}.join(';')}"
                  }
                  steps {
                      echo "$MY_VAR"
                  }
              }
          }
      }
      
      
      

       

       

      It is expected that MY_VAR is assigned the value '1=one;2=two' and its value is echoed in the console output, however the following exception is thrown:

      hudson.remoting.ProxyException: groovy.lang.MissingMethodException: No signature of method: java.util.LinkedHashMap.collect() is applicable for argument types: (org.codehaus.groovy.runtime.GStringImpl) values: [null=null]
      Possible solutions: collect(), collect(groovy.lang.Closure), collect(groovy.lang.Closure), collect(java.util.Collection, groovy.lang.Closure), collect(java.util.Collection, groovy.lang.Closure), clone()

      The same code evaluates successfully in scripted Pipeline. This Pipeline succeeds and reports the expected value:

      def myMap = ['1': 'one', '2': 'two']
      MY_VAR="${myMap.collect {key, value -> "$key=$value"}.join(';')}"
      echo MY_VAR
