java - Gradle 任务间歇性失败

问题描述

在运行 gradle 任务时，它会间歇性地失败（平均 10 次中有 1-2 次没有意义）

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) { }
    }
}

因为它错误地失败了（在手动执行相同的任务时它工作正常，但使用詹金斯它失败了）我添加了 catch (GradleException e) { } 但它仍然间歇性地失败，谁能指出我错过了什么？

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'.

我们还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.")
    }

解决方案

根本原因是java.net.SocketException: Connection reset。

这意味着网络有问题：

  • 也许服务器没有运行或无法访问
  • 也许您正在尝试连接到错误的 IP/主机名
  • 可能由于某些内部错误，服务器关闭了连接
  • 也许传输太慢并且连接超时
  • 也许你有一个糟糕的防火墙，等等。

您是否手动尝试了足够多次以 99.9% 确定它不会手动发生？你有没有在同一台机器上尝试过，使用相同版本的 Java、Gradle 和其他所有东西？您是否确定问题与时间或速度无关？

我最初的想法是您正在启动一个 docker 容器，之后您向服务发出 URL 请求，但您忘记了容器启动是异步的。换句话说，你不能保证当 docker-compose 完成时服务会真正运行。但这只是一个猜测。

尝试在发出 URL 请求之前添加延迟，以查看它是否进行了任何更改。正确的做法是循环轮询 URL，直到服务启动或超时。
