java - IntelliJ Idea 给出 java.lang.OutOfMemoryError : Java heap space error even after increasing heap size

Question

在 IntelliJ Idea 上编译我的 android 项目时，我反复遇到 java.lang.OutOfMemoryError: Java heap space 错误。

我通过链接 here 增加了我的 Java 堆空间然而这并没有解决问题。有趣的是，有时我的应用程序会编译，而有时由于 java 堆空间错误，应用程序不会编译。即使我没有对应用程序进行任何更改，它有时也会编译并有时会失败。

知道如何解决这个问题吗？

我正在编译一个 android 项目，可能是由于我拥有大量或资源(可绘制 hdpi、xhdpi、xxhdpi、large-hdpi、large-xhdpi、large-xxhdpi)吗？但是话又说回来，就像我说的那样，它有时会编译，有时却不会。我每次尝试编译大约 10 次，幸运的是它会成功一次。

这是错误:

转到设置(Mac 上的首选项)-> 编译器 -> Java 编译器 -> 最大堆大小 (MB)，并增加大小，然后重新启动 IntelliJ
