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

对我有效的解决方案,设置:<forkCount>0</forkCount>

i.e.

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-plugin</artifactId>
  <configuration>
    <forkCount>0</forkCount> 
    <argLine>-Xmx1024m -XX:MaxPermSize=256m</argLine>
  </configuration>
</plugin>

其他回答

在pom.xml中设置这一点对我来说很有效。 但是您应该查看文档以寻找其他解决方案 https://maven.apache.org/surefire/maven-surefire-plugin/examples/class-loading.html

       <plugin>

            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
                <!--these strange settings fixes a chrash and dumpstream from surefire when run from command line
                    Caused by: java.lang.ClassNotFoundException: org.apache.maven.surefire.booter.ForkedBooter
                -->
                <useSystemClassLoader>true</useSystemClassLoader>
                <useManifestOnlyJar>false</useManifestOnlyJar>
            </configuration>
        </plugin>

您需要检查您的机器是64位还是32位。如果你的机器是32位的,那么你的内存参数不应该超过4096,即使它应该低于4 GB。 但如果你的机器是64位的,那么安装Java 64位,并在mvn.bat中提供JAVA_HOME,指向Java 64位安装。

使用maven surefire 2.21.0我解决了reuseForks选项值从true变为false的问题:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.21.0</version>
            <configuration>
                <reuseForks>false</reuseForks>
            </configuration>
        </plugin>
    </plugins>
</build>

我正在构建的整个配置部分是这样的:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.21.0</version>
            <configuration>
                <testFailureIgnore>true</testFailureIgnore>
                <skip>false</skip>
                <reuseForks>false</reuseForks>
                <argLine>-Xmx1024m -XX:MaxPermSize=256m</argLine>
                <argLine>-Dfile.encoding=UTF-8</argLine>
                <useSystemClassLoader>false</useSystemClassLoader>
                <includes>
                    <!--Test* classes for the app testing -->
                    <include>**/directory/Test*.java</include>
                </includes>
            </configuration>
        </plugin>
    </plugins>
</build>

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,并添加了如下内容:

<argLine>-Xmx1024m -XX:MaxPermSize=256m</argLine>

整个plugin元素是:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-plugin</artifactId>
  <configuration>
    <forkCount>3</forkCount>
    <reuseForks>true</reuseForks>
    <argLine>-Xmx1024m -XX:MaxPermSize=256m</argLine>
  </configuration>
</plugin>
