java - Gradle任务间歇性失败

Question

在运行gradle任务时，它会间歇性地失败(平均10次中有1-2次失败)

task runIntProxy(dependsOn: [':int-proxy:getVersions',':infrastructure:dev:startNginx']) {
  group 'start'
  description 'Starts int-proxy'
    doLast {
        file(logsDir).mkdirs()
        def imageTag = readVersion('int_proxy_image_tag')

        command("docker-compose ${composeFiles} up -d", ['env': ['INT_PROXY_IMAGE_TAG': imageTag]])
        command("docker-compose ${composeFiles} logs -f", ['printOutput': false, 'waitForExit': false, 'outputFile': "$logsDir/int-proxy.log"])

        quiet "Running healthchecks:"
        println(intProxyStatus)
        try {
        def response = new URL(intProxyStatus).getContent().text
        println("output from URL:" + response)
      
        if(response.contains("alive")){
          quiet("Int-proxy is up and running")
        } else {
          throw new GradleException("Int-proxy is not up!")
        }
        } catch (GradleException e) { }
    }
}

由于它错误地失败了(在手动执行相同任务时可以正常工作，但使用jenkins却失败了)，我添加了catch(GradleException e){}，但仍然间歇性失败，有人可以指出我缺少什么吗？
错误代码如下

* What went wrong:
Execution failed for task ':int-proxy:runIntProxy'.
> java.net.SocketException: Connection reset

* Try:
Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':int-proxy:runIntProxy'.

我们也进行轮询以查看服务是否启动

if(!waitForNoConnection(intProxyStatus, 5, 5, 15)) {
      throw new GradleException("Couldn't stop int-proxy. You might need to forcefully kill it yourself.")
    }

Answer 1

根本原因是java.net.SocketException: Connection reset。
这意味着网络出了点问题:

也许服务器未运行或可达

也许您正在尝试连接到错误的IP /主机名

也许由于某些内部错误

，服务器关闭了连接

传输速度可能太慢，并且连接超时

也许您有一个糟糕的防火墙等。

您是否已经尝试了足够多次的手动操作，以确保99.9％的时间也不手动进行？您是否在同一台机器上，同一版本的Java，Gradle以及其他所有产品上尝试过它？您确定问题与时间或速度无关吗？
我最初的想法是，您正在启动一个docker容器，之后向服务发出URL请求，但是您忘记了容器启动是异步的。换句话说，您无法保证docker-compose完成后该服务将真正运行。但这只是一个猜测。
尝试在发出URL请求之前添加延迟，以查看是否进行了任何更改。正确的方法是循环轮询URL，直到服务启动或超时。
