Information:java: Errors occurred while compiling module 'game-gong'
Information:javac 7 was used to compile java sources
Information:Module "game-gong" was fully rebuilt due to project configuration/dependencies changes
Information:2018/2/25 下午4:46 - Compilation completed with 1 error and 11 warnings in 1m 54s 957ms
Error:java: OutOfMemoryError: insufficient memory原因：idea设置编译器内存默认为700MB，需求超过这个范围则会抛出以上错误
解决方案：
若是以下操作，无效果，尝试删除项目，重新导入。
1.打开idea setting
2.修改编译器内存上限
