Jenkins Pipeline Plugin : how to print stacktrace in a try/catch

[Nicolas Geraud]

Hi,

i want to add a try/catch/finaly block in my pipeline script.

try {
    println("    Release ${components.size()} components in parallel : ${componentListToPrint} \n")
    parallel parallelBuild
} catch(err) {
    echo "Exception thrown:\n ${err}"
    echo "Stacktrace:"
    err.printStackTrace()
    currentBuild.result = 'FAILURE'
} finally {
    return componentsReleased
}

The problem is that i'm not able to print the complete stacktrace (the stasktrace is essential for debugging purpose).

The question is : how to print the complete stacktrace as if there were no try / catch block ?
