Communication error with Jack server , try ‘jack-diagnose’ or see Jack server log 报错解决办法

报错log如下：

[100% 1/1] Ensure Jack server is installed and started

这里意思是说启动jack server失败，我们在prebuilts下用jack-admin命令确实是启动不了

android/prebuilts/sdk/tools$ ./jack-admin start-server

为什么会出现这种情况呢，我对比了其他同事的**.jack-server** 目录和 .jack-settings文件发现如下不同。

这是同事的jack-server目录文件:

liush@Ubunbtu-jcrjb-04:~/.jack-server$ ls -l
total 8952
-rw------- 1 liush liush    2094 Jan 29  2018 client.jks

打开/.jack-server/log/里面的log发现报错的地方是打开端口号错误了，通过查找其他解决办法，试了一下修改端口号的解决办法，发现是有效的，具体如下。

19:22:30.131: INFO: com.android.jack.server.JackHttpServer: Starting jack server version: 1.3-a8 '1.3' (291201 fcd657165d2fd6dcf1bf4c3002c9c8f75383e815 by android-jack-team@google.com)

        ... 3 more

1、 SERVER_PORT_SERVICE 和 SERVER_PORT_ADMIN 的端口号改大点的数字，不要和别人重复。

songzhihao@Ubunbtu-jcrjb-04:~$ cat .jack-settings 
# Server settings
SERVER_HOST=127.0.0.1
SERVER_PORT_SERVICE=8926 
SERVER_PORT_ADMIN=8927

# Internal, do not touch
SETTING_VERSION=4

2、在.java-server目录下新建config.properties 文件，内容如下，注意这里的service.port 和admin.port要和上面.jack-settings里面的一样。

#
#Thur April 8 20:08:16 CST 2021
jack.server.max-jars-size=104857600
jack.server.max-service=4
jack.server.service.port=8926
jack.server.max-service.by-mem=1\=2147483648\:2\=3221225472\:3\=4294967296
jack.server.admin.port=8927
jack.server.config.version=2
jack.server.time-out=7200

3、最后给 .java-server/config.properties chmod 600 的权限，这样编译任何模块就可以编译通过了

注意：如果改完config.properties还是报端口打开错误，试着进入android/prebuilts/sdk/tools目录执行下面的命令将 jack-server重启一下。

jack-admin kill-server jack-admin start-server
