Question

我知道这个问题一直存在很长时间，但是所有解决方案都对我没有成功

Maven throws "java.lang.OutOfMemoryError"

How to deal with "java.lang.OutOfMemoryError: Java heap space" error?

尽管我尝试了以上两种解决方案，还尝试了其他建议的选项其他答案仍然导致我遇到以下错误

说清楚点

我已经使用sure-fire来运行testng测试并相应地生成报告...所以我首先应用了添加argline的方法，但没有帮助。然后我尝试添加MAVEN_OPTS并增加了从256到1024范围的值，但最终没有添加JAVA_TOOL_OPTIONS，即使我尝试了多个值来指定

，它仍然不起作用

还有其他选择可以尝试解决问题吗？

不要标记此重复项...我需要比现有的更好的解决方案。

您可以像这样配置maven-surefire-plugin：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>x.x.x</version>
    <configuration>
        <argLine>-Xmx2048m -XX:MaxPermSize=1024m</argLine>
    </configuration>
  </plugin>

设置JVM参数。

Maven在生成Sure-fire报告时抛出“ java.lang.OutOfMemoryError”
