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

Maven Throws "java.lang.OutOfMemoryError" when generating Sure-fire reports

我知道这个问题出现很久了, 但是none的解决方案对我来说很成功

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,也尝试了建议的其他选项 其他答案我仍然在下面的错误中结束

说清楚,

我已经使用 sure-fire 运行 testng 测试并相应地生成报告...所以我首先应用添加 argline 的方法,它没有帮助。然后我尝试添加 MAVEN_OPTS 并增加了从 256 到 1024 的值,这些值都不起作用,最终添加了 JAVA_TOOL_OPTIONS,即使我尝试了多个值来指定

,它仍然不起作用

是否还有其他选择可以尝试解决问题

不要将此标记为重复...我需要比现有解决方案更好的解决方案。

您可以这样配置 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。
