how to execute a shell script in build flow "flow" dsl section

[niraj nandane]

I have installed "Build Flow Plugin" and created a build flow project . The commands like build("project-name") are working fine.
I want to execute a shell script which is at /root/niraj/muscript.sh ,which build the system. so i am doing like this
shell(" /root/niraj/muscript.sh") . But it is showing error.

Started by user anonymous
ERROR: Failed to run DSL Script
groovy.lang.MissingMethodException: No signature of method: com.cloudbees.plugins.flow.FlowDelegate.shell() 
is applicable for argument types: (java.lang.String) values: [muscript.sh]

can anyone tell me ? its urgent

I don't think the build flow supports running a shell script directly, you would need to build() a job that executes the shell script.

I think the choices are to use build-flow with separate jobs for every
step the dsl doesn't do directly, or use groovy build steps with your
own code to do what the dsl functions would have done.

But you must be doing something relatively complicated to need
build-flow at all. Maybe you should start with what you can't do with
a single ordinary job's build steps or a matrix job if you need
multiple variations of the same build. Build-flow is only needed when
you need to orchestrate some combination of jobs that simple chaining
or a matrix won't handle.

Here is my buildflow which executes a shell script...

Remember buildflow is DSL which is Groovy..

-----------------------------------

def JobCode = "REL"
def JobName = build.environment.get( "JOB_NAME" )
def BuildURL = build.environment.get( "BUILD_URL" )
def BuildNum = build.environment.get( "BUILD_NUMBER" )
def RevNum = build.environment.get( "GIT_COMMIT" )
def WrkSpce = build.environment.get( "WORKSPACE" )
def svnUrl = build.environment.get( "SVN_URL" )

out.println "Running Build for: "+JobName

def PathToWorkSpace = "jobs/"+JobName+"/workspace/"

def script=WrkSpce+"/Tools/PomVersionUpdater.sh "+JobCode+"-"+RevNum+BuildNum

def executeOnShell(String command) {
    return executeOnShell(command, new File(System.properties.'user.dir'))
}

private def executeOnShell(String command, File workingDir) {
    println command
    def process = new ProcessBuilder(addShellPrefix(command))
            .directory(workingDir)
            .redirectErrorStream(true)
            .start()
    process.inputStream.eachLine {println it}
    process.waitFor();
    return process.exitValue()
}

private def addShellPrefix(String command) {
    commandArray = new String[3]
    commandArray[0] = "sh"
    commandArray[1] = "-c"
    commandArray[2] = command
    return commandArray
}

executeOnShell(script)

build(JobCode+"-applicant-beans-bld", "PathToWorkSpace": PathToWorkSpace)

        }
