Question

We re upgrading to a newer version of Jenkins  2 60 1  and a groovy script which was working in the previous Jenkins version  1 596 2  no longer works   This is a Jenkins build project  which is parameterized and we re using a Groovy script to provide the choices for a Choice Provider  the Choice Provider is set to System Groovy Choice Parameter    We re trying to get access to the Jenkins environment variables and do so like this  this is part of the Groovy script    import hudson slaves EnvironmentVariablesNodeProperty import hudson EnvVars  EnvironmentVariablesNodeProperty prop   jenkins getGlobalNodeProperties   get EnvironmentVariablesNodeProperty class  EnvVars env   prop getEnvVars    def MY VAR   env  MY JENKINS VAR     However  I m getting the following error when running the script   Failed to execute script  groovy lang MissingPropertyException  No such property  jenkins for class  groovy lang Binding at groovy lang Binding getVariable Binding java 63  at org jenkinsci plugins scriptsecurity sandbox groovy SandboxInterceptor onGetProperty SandboxInterceptor java 224    It seems to me the  jenkins  reference is expected to be a built-in property provided by Jenkins or perhaps Groovy  but I can t find any information on what I need to do to make it accessible from the Groovy script   Thanks for any help

Please double check that jenkins is not blocking this import  Go to script approvals and check to see if it is blocking it  If it is click allow   https   jenkins io doc book managing script-approval

For me this problem occurred because I had a some invalid character in my Groovy script  In our case this was an extra blank line after the closing bracket of the script
