def runMavenCommand(String command) {
    def process = "mvn $command".execute()
    process.waitFor()

    def output = process.in.text
    def error = process.err.text

    if (output) {
        println "Output: $output"
    }

    if (error) {
        println "Error: $error"
    }
}

runMavenCommand("clean install")
