java - Intellij IDEA 项目构建从未完成

Question

我正在尝试构建我的 Java 项目，但该过程从未完成。 build 进度微调器会一直旋转下去，就好像它陷入了无限循环。

我的代码库通过 CI 编译需要 15 分钟，但 2 小时后 IDEA 仍然很忙。

为什么我的 IntelliJ IDEA 项目构建没有完成？

我不确定确定问题可能需要哪些额外信息；所以请告诉我，我很乐意提供。

IntelliJ IDEA 2017.3.2(社区版)Build 173.4127.27

Answer 1

内存不足

IntelliJ 的构建日志显示了一个OutOfMemoryError。

我may已达到 JDK 32 位的线程数限制，因此我更改为 JDK 64 位。

而且我将构建过程内存从 64m 增加到 128m。
