gradle - While循环监视Gradle中的任务

Question

我想监视在重新部署任务后创建的kubernetes pod，一旦完成，我想检查liquibase日志。如果成功，我要删除作业。我怎样才能做到这一点？我不想在重新部署后立即取消部署。因此，doLast不是一个选择。以下代码无法保持打印状态ob尚未完成

task undeployAfterCompleted() {
    group "kubernetes"
    description "Undeploy the liquibase update job after completion"

    def output = new ByteArrayOutputStream()
    commandLine "bash", "-c", "kubectl get po -n pbr | grep 'liquibase'  | awk '{ print \$3 }'"

    while(!output.toString().equals('Completed')) {
        sleep(5 * 1000)
        println "Job has not completed yet."
        commandLine "bash", "-c", "kubectl get po -n pbr | grep 'liquibase'  | awk '{ print \$3 }'"
    }

    tasks.undeploy.execute()
}

Answer 1

我添加了一个doLast块来实现这一点:

doLast {
    String status = getStatus()
    println status.length()
    while (status != "Completed") {
        println "not"
        sleep(5 * 1000)

        if (getStatus() == "Completed") {
            println "did"
            break
        }
    }
    tasks.undeploy.execute()
}
