Question

我正在尝试构建我的 Java 项目，但该过程永远不会完成。构建进度微调器只是永远旋转，好像它陷入无限循环一样。

我的代码库需要15分钟才能通过CI进行编译，但是2小时后IDEA仍然很忙。

为什么我的IntelliJ IDEA项目未完成？

我不确定识别问题可能需要哪些其他信息;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 OutOfMemoryError 。

I may已达到JDK 32位的线程数限制，因此我更改为JDK 64位。

我将构建过程内存从64m增加到128m。

Answer 2

构建速度过慢的其他原因是互联网连接速度较慢和 PC 上安装了防病毒软件。

通常构建对话框应该显示当前下载的文件。但是当连接速度太慢时，它不会显示这些信息。

您还可以在防病毒软件设置中从扫描中排除项目文件夹。
