Unable to use CliBuilder in a job-DSL

[Xavier Xemaire]

I would like to use CliBuilder to parse lines of a steerfile to build jobs.
But I get an exception:

java.lang.NoClassDefFoundError: org/apache/commons/cli/ParseException

I know that to be able to use CliBuilder with GroovyShell, I need to add commons-cli.jar (here Version 1.2) in the field: Additional classpath.

But I still get the exception.

My Job DSL:

import org.apache.commons.cli.*
def cli = new CliBuilder(usage: 'Hello World')

def giturl = 'https://github.com/quidryan/aws-sdk-test.git'
job("DSL-Tutorial-1-Test-1") {
    scm {
        git(giturl)
    }
    steps {
        maven("test -Dtest.suite=1")
    }
}

The exception:

My Configuration:

Jenkins: 2.32.2
Job-DSL: 1.58
Plattform: RHEL 7.1

I have run the job builder locally on my PC (see adding additionalClasspath to standalone scripts (javaposse.jobdsl.Run) ) without problem (the script is in d:\temp\test.groovy):

set CLI_JAR=d:\repos\DEPLOY\jenkins_dsl\job-DSL\download-cli\target\runtime\libs\commons-cli-1.2.jar

set DSL_LIB=d:\repos\3pp\job-dsl-plugin\job-dsl-core\build\one-jar-build\lib

set DSL_MAIN_JAR=d:\repos\3pp\job-dsl-plugin\job-dsl-core\build\one-jar-build\main\main.jar

java -cp %CLI_JAR%;%DSL_LIB%\*;%DSL_MAIN_JAR% javaposse.jobdsl.Run d:\temp\test.groovy

Processing DSL script test.groovy

Information: From d:\temp\test.groovy, Generated item: GeneratedJob{name='DSL-Tutorial-1-Test-1'}

Is there some known restrictions with the feature additional Classpath on jenkins Server?
Is there a way to use CliBuilder in a job-DSL?

Thanks in advance
Xavier

Check you additional classpath setting. If the classpath points to a non-existing JAR file, the file will be ignored and the classes are not found.

This scripts works for me:

import org.apache.commons.cli.*
 
CommandLineParser parser = new BasicParser()

Hi Daniel,

Thank you very much for your answer.

Your script works for me too. But when I use CliBuilder I get the exception.
So it seems that there is a problem with CliBuilder but not with the classes that are defined in commons-cli.jar:
I was also able to create a new 'Options' Object.

In the meantime I do not use CliBuilder any longer.
I'm a newbie in groovy and I don't understand why it is possible to use the CliBuilder with the job builder locally and not in the jenkins-server.
This seems to be a problem with the black magic of class loading of jenkins.
