a speical character issue on jenkins jobdsl plugin

Issue

I change one jobDsl groovy file for jenkins, try to add some shell script there :

<br /> shell (
"""
#!/bin/bash
pid=$(netstat -tulnp | awk -vport=28189 '$4~":"port"{print 0+$7}')
echo "$pid"
if [[ -n $pid ]]; then
  kill -9 "$pid"
fi
cd app/sdk
/opt/maven/bin/mvn clean deploy
“”"

but when I tried to regnerate the jenkins job, I got this error :

<br />ERROR: Build step failed with exception
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Script1.groovy: 13: illegal string body character after dollar sign;
   solution: either escape a literal dollar sign "\$5" or bracket the value expression "${5}" @ line 13, column 11.
       shell (

the problem is here : `

either escape a literal dollar sign “\$5” or bracket the value expression “${5}” @ line 13, column 11.
`

Solution

the problem caused by the $ sign, to fix it, here is the solution:

<br />#!/bin/bash
pid=\$(netstat -tulnp | awk -vport=28189 '\$4~":"port"{print 0+\$7}')
echo "\$pid"
if [[ -n \$pid ]]; then
  kill -9 "\$pid"
fi

test

<br />$ ./gradlew clean jobDsl
$ ls
README.md             gradle                gradlew               run.jenkins.docker.sh
build.gradle          gradle.properties     gradlew.bat           src
Then you can find your generated job xml here:
$ less build/jobs/qbo-test-master-build-commit.xml
