我使用Cucumber进行Java实现，并在 Jenkins 上运行我的测试套件后，我得到了 Java堆空间错误。我试图为进程提高内存但仍然出错。我还试图为确保火灾和故障安全的maven插件提高内存，但由于在测试/集成阶段没有发生问题，我仍然无法工作。
当编译并生成JSON报告时，有时也会在运行测试时发生。关于它的任何线索？
错误跟踪是：

当您使用Scenario对象在黄瓜HTML报告中嵌入自己的文本时，我经常会看到这种情况。我曾经使用scenario.write(myObject.toString())在我的黄瓜报告中嵌入了整个JSON对象，这导致Cucumber Jenkins插件因你提到的Java堆空间错误而崩溃。在我将这些写入限制在报告之后，一切都开始正常工作。
