IDEA load project 慢问题排查

去打开 IDEA 的 DEBUG 日志，日志地址在 help - Show log in finder 里，日志配置文件在 /Applications/IntelliJ IDEA.app/Contents/bin/log.xml。启动时的日志有一段明显很值得怀疑：

1
2

2018-05-06 15:34:45,576 [  93768]   INFO - ij.components.ComponentManager - com.seventh7.mybatis.ref.CmProject initialized in 75086 ms
2018-05-06 15:34:45,588 [  93780]   INFO - ellij.project.impl.ProjectImpl - 152 project components initialized in 75849 ms

com.seventh7.mybatis.ref.CmProject 初始化耗了 75 秒。去把 MyBatis 插件禁用以后重新测试：

1	2018-05-06 15:40:13,639 [ 138286] INFO - ellij.project.impl.ProjectImpl - 150 project components initialized in 999 ms

禁用以后明显解决了，这个插件记得是之前安装的破解的 MyBatis 插件。重新去 idea 插件仓库里搜，现在有了一个 Free MyBatis Plugin，不用再找破解版的了：

后来又出现了新的问题，启动的时候有两次 SocketException: Operation timed out。观察 INFO 日志的时候，这两个异常日志一出现，其他的启动日志就立刻打出来，IDEA 也顺利打开了：

2018-05-07 09:30:56,988 [ 116724]   INFO - cloudConfig.CloudConfigManager - Operation timed out (Read failed)
