Android系统编译之Communication error with Jack server (35), try ‘jack-diagnose‘ or see Jack server log

场景

在进行Android系统开发时，在liunx编译时发生问题，描述如下：

ninja: build stopped: subcommand failed.
build/core/ninja.mk:148: recipe for target 'ninja_wrapper' failed
make: *** [ninja_wrapper] Error 1

向上查找发现问题点

Jack server already installed in "/home/**/.jack-server"
Communication error with Jack server (35), try 'jack-diagnose' or see Jack server log
SSL error when connecting to the Jack server. Try 'jack-diagnose'
SSL error when connecting to the Jack server. Try 'jack-diagnose'

个人分析

根据解释能看到建议查看 jack-diagnose或Jack server log
通过查看jack-diagnose并无什么信息
而Jack server log信息如下

17:35:29.750: INFO: com.android.jack.server.JackHttpServer: Loading config of jack server version: 1.3-a11 '1.3' (402300 704631c4e9bbfb4e8b052365140f79974b9f4cf4 by [e-mail])

截止到此处依旧不能看到问题，貌似一切正常

网上分析

分析1

原因：jack不支持多用户同时编译，所以经常出现jack server报错的现象
解决方法：

编辑 $home/.jack，$home/.jack-settings 和 $home/.jack-server/config.properties,修改SERVER_PORT_SERVICE和SERVER_PORT_ADMIN的端口号，然后保存。
如果权限不对可以执行下面的命令修改权限：
chmod 600 .jack
chmod 600 .jack-settings
chmod 700 .jack-server
查看jack server是否启动
cd prebuilts/sdk/tools ./jack-admin start-server/stop-server
jack-admin server-log命令来查找log所在目录

测试结果：失败，应该不是遇到的问题

分析2

原因1：权限问题

查看是否为权限问题：

运行失败时进入~/.jack-server/logs目录查看日志，如果出现权限问题修改以下两个文件权限:
sudo chmod 777 ~/.jack-settings
sudo chmod 777 ~/.jack-server/config.properties

原因2：端口占用

正常情况默认端口没有问题的不需要修改、一般编译突然中上就会产生端口占用，执行命令杀掉进程解除端口占用或修改端口
解决方案：

1、系统源码目录下，执行以下命令：
./prebuilts/sdk/tools/jack-admin kill-server
2、如果执行jack-admin kill-server还存在端口占用问题，可修改端口试试：
vi ~/.jack-settings
SERVER_PORT_SERVICE=8076
SERVER_PORT_ADMIN=8077
vi ~/.jack-server/config.properties
jack.server.service.port=8076
jack.server.admin.port=8077
注意：service、admin端口，两个文件需要保持一至

原因3：删除 TLSv1, TLSv1.1

解决方案：

sudo vi /etc/java-8-openjdk/security/java.security
查找”jdk.tls.disabledAlgorithms=“删除TLSv1, TLSv1.1，如下：
jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA,

测试结论

失败，在网上看到相似报错，但是经过各种测试后发现依旧无效

解决方案

结论：使用./jack-admin kill-server，再开启 ./jack-admin start-server
在开发过程中，需要先对jack server是否安装，是否启动有概念，通过使用
./jack-admin start-server ,先进入项目目录

**@ubuntu:~/Project/MTK**/prebuilts/sdk/tools$ ./jack-admin start-server 
Communication error with Jack server (35), try 'jack-diagnose' or see Jack server log

当开始报错时，可以确定没有启动，但是可以确定已经安装
网上有方案，要求执行./jack-admin stop-server，再开启 ./jack-admin start-server ，但是该方案失败。
然后发现有方案使用./jack-admin kill-server，再开启 ./jack-admin start-server，执行后成功

**@ubuntu:~/Project/MTK**/prebuilts/sdk/tools$ ./jack-admin kill-server
Killing background server
**@ubuntu:~/Project/MTK**/prebuilts/sdk/tools$ ./jack-admin start-server
Launching Jack server java -XX:MaxJavaStackTraceDepth=-1 -Djava.io.tmpdir=/tmp -Dfile.encoding=UTF-jack-server/launcher.jar com.android.jack.launcher.ServerLauncher
**@ubuntu:~/Project/MTK**/prebuilts/sdk/tools$ ./jack-admin start-server
Server is already running

当打印“Server is already running”明显表面已经正常。
疑问：还是不理解为什么需要kill，而stop却不行

说明

其实网上还有很多其他关于jack的问题及解决方案，但明显本次问题并不是出错，只是操作失误，导致被关闭
