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。

当前回答

最近travis终止了一个测试的执行(没有改变任何相关的东西(以及在开发人员机器上成功的构建!)),因此BUILD FAILURE。 原因之一是这样的(见@agudian的答案):

Surefire不支持调用System.exit()的测试或任何引用库

(因为测试类确实称为System.exit(-1))。

相反,使用简单的return语句会有所帮助。 为了让travis再次开心,我还必须添加@xiaohuo提供的surefire参数(<argLine>)。(此外,我必须删除-XX:MaxPermSize=256m,以便能够在我的一个台式机上构建)

只做这两件事中的一件是行不通的。

要了解更多背景知识,请阅读何时调用系统。退出Java。

其他回答

我更新了surefire插件如下,这解决了我的问题:

           <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.22.2</version>
                <configuration>
                    <argLine>-Xmx1024m -XX:MaxPermSize=256m</argLine>
                    <forkCount>1</forkCount>
                    <reuseForks>true</reuseForks>
                    <runOrder>alphabetical</runOrder>
                </configuration>
            </plugin>

关闭maven-surefile-plugin的useSystemClassLoader应该会有帮助

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.22.0</version>
    <configuration>
        <useSystemClassLoader>false</useSystemClassLoader>
    </configuration>
</plugin>

我今天也遇到了同样的问题,对我来说,真正的问题是在日志中进一步报告的消息不能使用threadCount参数小于1;1 > 0。 当在surefire-plugin配置中添加<threadCount>1</threadCount>时,其他错误消失。

Full plugin config:
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.18.1</version>
            <dependencies>
                <dependency>
                    <groupId>org.apache.maven.surefire</groupId>
                    <artifactId>surefire-junit47</artifactId>
                    <version>2.18.1</version>
                </dependency>
                <dependency>
                    <groupId>org.apache.maven.surefire</groupId>
                    <artifactId>surefire-testng</artifactId>
                    <version>2.18.1</version>
                </dependency>
            </dependencies>
            <configuration>
                <threadCount>1</threadCount>
            </configuration>
        </plugin>

...是的,为了向后兼容,我在这个测试框架中同时使用了junit和testng。

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.

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)。
