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

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>

其他回答

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

在这个答案中找出答案

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>

在我的情况下,通过设置MAVEN_OPTS增加内存有助于:

set MAVEN_OPTS=-Xmx1024m

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>

导致:java.util.concurrent.ExecutionException: java.lang.RuntimeException:分叉虚拟机未正确告别而终止。虚拟机崩溃或系统崩溃。退出叫什么?”

如果使用不兼容的java版本,则可能出现此问题。喜欢使用新版本的java,而代码支持一些其他版本。
