Pass groovy variable to shell script

Question

I just started learning groovy.I want to pass the svnSourcePath and svnDestPath to shell script in the svn copy command. But URL not rendered.

node {
 stage          


        

Answer 1

added the single quotes and plus operater('+ variable +') around the variable. Now it is working

svn copy '''+svnSourcePath+' '+svnDestPath+''' -m 'promote dev to test' --username $SVN_USER --password $SVN_PWD '''

Answer 2

You can use """ content $var """. """ allows string interpolation in the here doc; ''' does not.

Answer 3

only one time double quotes would also work

stage('test') {  
  steps {  
    script {  
      for(job in env.JOB_NAMES.split(',')) {  
        println(job);  
        sh "bash jenkins/script.sh $job"  
        sh "echo $job"  
      }  
    }//end of script  
  }//end of steps  
}//end of stage test

+1 to Selvam answer

following is my use case with parameter plugin

String parameter name: pipelineParameter

Default value: 4

node {
  stage('test') {
        withCredentials([[...]]) {
          def pipelineValue = "${pipelineParameter}"  //declare the parameter in groovy and use it in shellscript
          sh '''
             echo '''+pipelineValue+' abcd''''
             '''
        }
}}

The above prints 4 abcd
