Jenkins Scripted Pipeline returnStatus null-CodePudding

I have created a Scripted pipeline Jenkins job, in one of the stage I need to run a java file example:- java -jar accountrans.jar and I need to return the value to the variable.

stage('Account Process')
{    
    sh 'curl --noproxy "*" -X GET https://paraforce.com/artifactory/account/accountrans.jar -o accountrans.jar'    
    def acctval = sh script: "java -jar accountrans.jar . ", returnStatus: true    
    echo "Account Trans Value : " $acctval 
}

I am getting error message java.lang.NullPointerException: Cannot get property 'java.lang.ClassCastException: body return value null is not boolean' on null object

When I ran the jar file from the command line I am able to view the return value.

Please help how to fix it.

I'm assuming your program outputs something to the Stdout. But you are trying to retreive the status code. Instead of returnStatus try returnStdout.

stage('Account Process')
{    
    sh 'curl --noproxy "*" -X GET https://paraforce.com/artifactory/account/accountrans.jar -o accountrans.jar'    
    def acctval = sh script: "java -jar accountrans.jar . ", returnStdout: true    
    echo "Account Trans Value : " $acctval 
}

I am not sure but try curly braces after sh.

stage('Account Process')
{    
    sh 'curl --noproxy "*" -X GET https://paraforce.com/artifactory/account/accountrans.jar -o accountrans.jar'    
    def acctval = sh {script: "java -jar accountrans.jar . ", returnStdout: true }   
    echo "Account Trans Value : " $acctval 
}
