Getting unknown type : import in groovy in Jenkins Pipeline

Question

I am trying to create a Jenkins Pipeline Script using groovy. However, the import statement is giving me a compilation error - Unknown Type : Import. Not sure why.

Answer 1

You should define import jxl.* at the top of the pipeline script, e.g.

import jxl.*

node {
    stage('Execute Tests') {
        try {
           dir('.') {
               sh '......' // etc.
           }
        }
    }
}

When you added it inside node {} block Jenkins was looking for a method instead of import class statement. The good convention is to put all import statements at the top of the Groovy file.
