启动分叉时发生 Maven 错误，请在日志中检查输出

Question

我使用 Maven、docker-maven-plugin 和 Spring Boot。现在我遇到了以下问题：

我读到这个问题可能与 maven-surefire-plugin 有关，所以我已添加到我的父 pom：

<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<forkCount>0</forkCount>
</configuration>
</plugin>
<plugins>
</pluginManagement>

和继承的诗：

<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
</plugin>
</plugins>

但这无济于事。

如何解决这个问题？

Answer 1

我在本地环境中也遇到过这个问题(构建在其他环境中运行良好)。所以我没有修改pom.xml，而是添加了forkCount=0作为命令行参数，它解决了这个问题。喜欢：

mvn clean install -DforkCount=0

Answer 2

我遇到了同样的问题，添加以下内容对我有用： 版本 3.0.0-M3 解决了这个问题

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>3.0.0-M3</version>
<configuration>
<forkCount>0</forkCount>
<testFailureIgnore>true</testFailureIgnore>
</configuration>
</plugin>

Answer 3

我也面临着同样的问题。

[ERROR] Please refer to dump files (if any exist) [date].dump, [date]-jvmRun[N].dump and [date].dumpstream.
[ERROR] org.apache.maven.surefire.booter.SurefireBooterForkException: Error occurred in starting fork, check output in log

在我的上下文中，我正在构建一个 Spring 启动应用程序。所有测试都正常，但是，由于应用程序代码关闭过程中的问题，应用程序无法正确关闭。我猜该过程没有返回等于 0 的退出代码。

一旦我们解决了这个关机问题，这个万无一失的插件异常就不再发生。

这可能是您问题的提示。

Answer 4

将 useSystemClassloader 设置为 false：

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<useSystemClassLoader>false</useSystemClassLoader>
</configuration>
</plugin>

Answer 5

我有一个类似的错误，因为我的分支名称中有一个破折号-，而 Jenkins 失败了。

[ERROR] Error occurred in starting fork, check output in log 
[ERROR] Process Exit Code: 1 
[ERROR] org.apache.maven.surefire.booter.SurefireBooterForkException: The forked VM terminated without properly saying goodbye. VM crash or System.exit called? ... 
[ERROR] Error occurred in starting fork, check output in log [ERROR] Process Exit Code: 1 
[ERROR] at org.apache.maven.plugin.surefire.booterclient.ForkStarter.fork(ForkStarter.java:671) 
[ERROR] at org.apache.maven.plugin.surefire.booterclient.ForkStarter.fork(ForkStarter.java:533) 
[ERROR] at org.apache.maven.plugin.surefire.booterclient.ForkStarter.run(ForkStarter.java:278) 
[ERROR] at org.apache.maven.plugin.surefire.booterclient.ForkStarter.run(ForkStarter.java:244)

[ERROR] at org.apache.maven.plugin.surefire.AbstractSurefireMojo.execute(AbstractSurefireMojo.java:854)

在用另一个名字做了一个相同的分支后，我又工作了。

Answer 6

除了aure_bobo回答谁说遗留代码可能导致退出代码！= 0 ：

就我而言，我的 IT 阶段都取得了成功，并且仅在 CI/CD 上收到此错误：我无法在本地诊断/重现：因此无法知道原因，并且模块在万无一失的分叉关闭时出错：没有来自 surefire 3.0.0-M5 代码的堆栈跟踪，因为它不是超时。

所以我使用了这个技巧：

• 要对应用程序故障进行故障排除，请暂时将故障安全插件配置为永不分叉(文档：forkMode>never)：

  <plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-failsafe-plugin</artifactId>
  <version>${maven-failsafe-plugin.version}</version>
  <configuration>
  <!-- (...) -->
  <forkMode>never</forkMode>
  <!-- (...) -->
  </configuration>
  

就我而言，使用此技巧，我能够重现：所有IT都成功，然后在关闭时获得完整的堆栈跟踪。
