报错：

解决：

1. 在源代码根目录，执行命令得到报错日志压缩包文件，然后解压文件打开logs/jack-server-0-0.log查看日志；
2. 日志显示 Caused by: java.io.IOException: './config.properties' has the following invalid permissions ---rw----，有类似错误的就说明该文件权限没给对；

Caused by: java.io.IOException: './config.properties' has the following invalid permissions ---rw----
	at com.android.jack.server.PosixFileAccess.checkAccessibleOnlyByOwner(PosixFileAccess.java:62)
	at com.android.jack.server.JackHttpServer.checkAccessRight(JackHttpServer.java:865)
	at com.android.jack.server.JackHttpServer.loadConfig(JackHttpServer.java:720)
	at com.android.jack.server.JackHttpServer.<init>(JackHttpServer.java:579)
	at com.android.jack.server.JackServerImpl.run(JackServerImpl.java:66)
	... 2 more

3. 去到 ~/.jack-server 目录，修改权限即可。

cd ~/.jack-server
chmod 600 config.properties
