I am trying to configure jenkins job with groovy scripts, I donot know what I am doing wrong with the configuration that I could not execute even a simple groovy command like
println System.getenv("PATH")
it shows the following stack trace when the jenkins tries to build then following error is thrown
[workspace] $ groovy "C:\Program Files (x86)\Jenkins\jobs\{Project_Name}\workspace\hudson2392295018240496017.groovy"

Build step 'Execute Groovy script' marked build as failure
Finished: FAILURE
I am using default groovy version in jenkins configuration and have installed the jenkins plugins for groovy.
I am new to both jenkins and groovy. Thanks in advance.

Groovy scripts are not necessarily suitable for all users, so Jenkins created the Declarative pipeline. The Declarative Pipeline syntax is more stringent. It needs to use Jenkins' predefined DSL structure, which provides a simpler and more assertive syntax for writing Jenkins pipelines.
Groovy is a very powerful language which offers the ability to do practically anything Java can do including: Create sub-processes and execute arbitrary commands on the Jenkins controller and agents. It can even read files in which the Jenkins controller has access to on the host (like /etc/passwd )
In Jenkinsfile, simply use load step to load the Groovy script. After the Groovy script is loaded, the functions insides can be used where it can be referenced, as shown above.
You need to have an install of Groovy which your Jenkins can see - which is the default option
Alternatively, you can add one in the global config
which can then be used in the build step
