maven - 在 Java 堆空间异常上运行 Cucumber 测试后 Jenkins 构建失败

Question

使用 Jenkins 构建时出现以下异常。运行 Cucumber 测试后会引发此异常。

谁能说出 java 堆空间上失败的确切位置吗？

您知道可以采取什么措施来解决这个问题吗？

一些背景:在 Cucumber 测试期间，我有一个 java 堆空间，在增加内存后，Cucumber 测试通过了，但之后我立即得到了这个 java 堆空间。

谢谢

进入 Jenkins 设置并将环境变量 MAVEN_OPTS 添加到 -Xmx512m -XX:MaxPermSize=256m。看起来测试完成后它正在尝试解析结果，但 XML 文件太大。
