IntelliJ Error: java.lang.OutOfMemoryError: GC overhead limit exceeded

问题

我在 IntelliJ Idea Ultimate Edition 2020.2.2 上运行 Grails 2.5.0。它可以正常编译和构建代码，但不断抛出“java.lang.OutOfMemoryError: GC overhead limit exceeded”错误（完整错误信息在末尾粘贴）。基于对这个错误的研究，我尝试了以下方法：

1.) 增加构建过程的堆大小（尝试过 2G、4G 和 6G）
https://intellij-support.jetbrains.com/hc/en-us/community/posts/360003315120-GC-overhead-limit-exceeded

2.) 增加内存堆大小（尝试过 2G、4G 和 6G）
https://www.jetbrains.com/help/idea/increasing-memory-heap.html

3.) 在启动配置中增加 JVM 的最大内存设置（尝试过 2G、4G 和 6G）

我看到修复此错误的方法之一是“尽可能重用现有对象以节省一些内存”。然而，我坚信这不是代码的问题，而是 IDE 设置的问题。我使用的代码在生产网站上运行良好，没有错误，而这个 OutOfMemoryError 只在我的本地机器上出现。我会感激任何人能够提供的帮助，谢谢！！！

I'm running Grails 2.5.0 on IntelliJ Idea Ultimate Edition 2020.2.2 . It compiles and builds the code just fine but it keeps throwing a "java.lang.OutOfMemoryError: GC overhead limit exceeded" error (the entire error is copy and pasted at the end). Here are the things I've tried based off researching this error:

1.) Increasing build process heap size (tried at 2G, 4G, and 6G)
https://intellij-support.jetbrains.com/hc/en-us/community/posts/360003315120-GC-overhead-limit-exceeded

2.) Increasing memory heap size (tried at 2G, 4G, and 6G)
https://www.jetbrains.com/help/idea/increasing-memory-heap.html

3.) Increasing the maximum memory setting for the JVM in the launch configuration (tried at 2G, 4G, and 6G)

I saw that one of the fixes for this error is to "Reuse existing objects when possible to save some memory." However I believe strongly that this is not an issue with the code but with settings on my IDE. The code I am using works fine without errors on the production website and this OutOfMemoryError only appears on my local machine. I would appreciate any help anyone can give, thank you!!!
