Intellij IDEA项目构建无法完成

Question

我正在尝试构建我的Java项目，但是该过程从未完成。构建进度指示器一直旋转，就像它被卡在无限循环中一样。

我的代码库需要15分钟通过CI进行编译，但经过2个小时后，IDEA仍然忙碌。

为什么我的IntelliJ IDEA项目构建没有完成？

我不确定还需要什么附加信息才能识别问题，所以请告诉我，我会很乐意提供。

IntelliJ IDEA 2017.3.2（社区版）Build 173.4127.27

也许通过 IntelliJ Forum 或者他们的bugtracker 会得到更好的回答。虽然一个好的开始可能是检查日志文件。 - SurfMan

谢谢！不知道为什么我没想到查看IDEA的日志。 - user2818782

Answer 1

内存不足

IntelliJ的构建日志显示了一个OutOfMemoryError错误。

我可能已经达到了JDK 32位的线程数限制，所以我改用了JDK 64位。

并且我将构建过程内存从64m增加到了128m。

Answer 2

构建速度过慢的其他原因可能是网络连接较慢以及计算机上安装了杀毒软件。

通常情况下，构建对话框应该显示当前正在下载的文件。但当连接过慢时，它不会显示这些信息。

您还可以在杀毒软件设置中排除项目文件夹的扫描。
