分叉的VM没有正确地说再见就终止了。虚拟机崩溃或系统崩溃。出口被称为

请帮我解决这个问题。我不太明白日志中的错误是什么意思。

当我遇到这个错误时，这是由于我的ulimit打开文件(ulimit -n)太低。它(不知何故)被设置为仅256:

% ulimit -n
256

在我增加限制后，错误消失了:

% ulimit -n 3072
% ulimit -n     
3072

您的系统可能不允许将限制设置得这么高。例如，当我试图使用更大的数字时，就会发生这种情况:

% ulimit -n 3073
ulimit: setrlimit failed: invalid argument

或者这可能低于您现有的限制，您可能面临不同的根本原因。

Surefire FAQ的这一部分可以帮助你:

Surefire fails with the message "The forked VM terminated without properly saying goodbye" Surefire does not support tests or any referenced libraries calling System.exit() at any time. If they do so, they are incompatible with surefire and you should probably file an issue with the library/vendor. Alternatively the forked VM could also crash for a number of reasons, which can also make this issue happen. Look for the classical "hs_err*" files indicating VM crashes or examine the log output from running maven when the tests execute. Some "extraordinary" output from crashing processes may be dumped to the console/log. If this happens on a CI environment and only after some time runs there is a fair chance your test suite is leaking some kind of OS-level resource that makes things worse for every run. Regular os-level monitoring tools may give you some indication.

测试中使用的分叉JVM内存不足。解决方案是禁用分叉JVM并在主JVM上运行测试，以确保有足够的内存，或者通过参数来增加分叉JVM的内存

版本2.22.2在fork jvm方面存在实际问题。使用版本2.20 -它的工作就像一个魅力!

<groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
<version>2.20</version>

我在MacOS上远程调试端口5005上的Selenium测试代码时也遇到了这个问题。这个问题原来是由一个仍然运行的剩余的surefire-fork jvm引起的。Eclipse IDE终端的日志输出没有显示底层问题“Address already in use”。只有当我在MacOS终端上运行Eclipse实际试图运行的相同命令时，才会显示日志消息:

/bin/sh -c cd /path/to/your/project/directory && /Library/Java/JavaVirtualMachines/adoptopenjdk-8.使用实例jdk/Contents/Home/jre/bin/java -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005 -jar /path/to/target/surefire/surefirebooter230340673926465933.jar /path/to/target/surefire 2019-06-28T10-50-02_140-jvmRun1 surefire6455775580414993159tmp surefire_02461993428448591420tmp

杀死流氓JVM实例(在Activity Monitor中查找java进程名)解决了这个问题。顺便说一下，我正在运行surefire插件版本2.21.0，与开放jdk 8 (v1.8.0_212)没有问题。注意，所有路径都将特定于您的构建环境，可能还有端口(address=5005)。

我也遇到了同样的问题，我使用了Oracle的Java 8而不是Openjdk的Java 10来解决这个问题
