添加配置文件后，我可以删除这个错误:

<profile>

似乎这是一个关于maven的问题

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)。

我使用的文件夹名为test&demo，所以它给出了这个问题(虚拟机没有正确地说再见就终止了。虚拟机崩溃或系统崩溃。退出调用)，但当我给文件夹名称为test_demo，然后它解决了这个问题。(有“&”符号的windows操作系统存在此问题。)

将“&”替换为“_”

此问题可能是由文件夹名称中的一些特殊符号或额外空格引起的。

我忘记在我的Java 7项目的pom.xml中声明maven-surefire，所以它在maven的运行时默认使用Java 8版本。(我以为是在父母那里宣布的)

在pom的构建部分添加surefire解决了这个问题。

<build>
    <plugins>
         <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.12</version>
            <configuration>
                <argLine>-XX:-UseSplitVerifier</argLine>
                <skip>${maven.skip}</skip>
                <skipTests>${maven.skipTests}</skipTests>
             </configuration>
         </plugin>
    </plugins>
</build>

这似乎是某些Windows机器上的线程同步问题。如果你在Windows上遇到这个问题，试着将输出重定向到一个文件:mvn clean install > output.txt

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.
