本文介绍了调试surefire的策略“分叉的虚拟机终止而没有说再见。 VM崩溃或System.exit调用？“的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在开发一个相当复杂的java项目，它有许多依赖项和许多单元测试。

I am working on a rather complex java project with many dependencies and many unit tests.

我在mac（mavericks）上使用java 1.6.0_65和maven 3.0 .5使用maven-surefire-plugin：2.16在几个forks中运行。
我的问题是使用多个forks运行此设置会导致fork退出：

I am using java 1.6.0_65 on mac (mavericks) with maven 3.0.5 with maven-surefire-plugin:2.16 running in several forks. My problem is that running this setup with several forks causes a fork to exit with:


分叉的VM终止而不说正确再见.VM崩溃或
System.exit调用？

"The forked VM terminated without saying properly goodbye. VM crash or System.exit called ?"

只用一个fork运行它不会产生问题（并且一切都过去了）

running this with only one fork does not produce the problem (and everything passes)

有一些关于这个问题的信息，包括这个StackOverflow问题和这个万无一失的错误（现在似乎已经解决了）

There is some information out there about this problem including this StackOverflow question and this surefire bug (which seems to be solved by now)

我知道这种情况的答案是在我的代码中找到什么调用System.exit（） - 我找不到任何东西。

I am aware that the "Answer" to this situation is to find what in my code calls System.exit() - Nothing i could find.

或者是什么导致我的JVM崩溃 - 没有hs_pid崩溃报告。

Or what causes my JVM to crash - there are no hs_pid crash reports.

我的问题是什么样的策略可以用来找到找到这个原因？
为了澄清，我对上面提到的答案不感兴趣，但是找到它的起源。 （或者甚至更好地说明可能导致这种情况的不同答案）

My Question is what what kind of strategy can i use to find a locate this cause? To clarify, I am not interested in the answer noted above, but a way to find where it is originating from. (Or even better a different answer altogether to what might be causing this )

我的Surefire配置是:(但我做了尝试其他组合）

my Surefire configuration is: (but i did try other combinations)

<parallel>classes</parallel>
<threadCount>1</threadCount>
<forkCount>1C</forkCount>
<reuseForks>false</reuseForks>
<useSystemClassLoader>false</useSystemClassLoader>
<useManifestOnlyJar>true</useManifestOnlyJar>
<useFile>true</useFile>
<redirectTestOutputToFile>true</redirectTestOutputToFile>
<runOrder>alphabetical</runOrder>





更新＃1
在运行maven目标后添加相关的输出--debug（-X）

Update #1 adding the relevant out put after running the maven goal with --debug (-X)

推荐答案

步骤：

（1）使用 -e 运行mvn并执行 -X 获取更多调试信息的选项。

(1) Run mvn with the -e and -X options to get more debug information.

（2）在输出中查找错误。在我的例子中，当我运行mvn命令时，输出的一部分包括：

(2) Look for "Error" in the output. In my case, when I ran the mvn command, part of the output included:

[ERROR] Command wascmd.exe /X /C "C:\dev\dev-tools\.....

（ 3）直接在命令shell中执行有问题的命令。

(3) Execute the problematic command directly in the command shell.

在我的情况下，执行

cmd.exe /X /C "C:\dev\dev-tools\....

$ b来自命令行的
$ b

导致OutOfMemoryError。

from the command line resulted in an OutOfMemoryError.
