一、编译android sdk 出现下面的错误 Jack server failed to (re)start,try 'jack-diagnose' or see Jack server log,SSL error when connecting to the Jack server. Try 'jack-diagnose'。

二、网上大多都是说修改/home/user/.jack-server/config.properties 和 /home/user/.jack-settings里面的端口号，但是尝试多次还是编译失败。
三， 分析error log： cd prebuilts/sdk/tools/ 然后执行./jack-admin dump-report 看log，有这样一行
* gnutls_handshake() failed: The TLS connection was non-properly terminated.
明显是什么gnutls_handshake() failed: The TLS connection was non-properly terminated.网络链接和鉴权等错误，和端口号一毛钱关系都没有。
三、解决方案
四、源码工程jack相关配置，在Android 7.0的工程中进行编译以前，运行以下命令，进行交互。
进入源码相应目录 prebuilts/sdk/tools$ 运行下面命令：
1）、 jack-admin start-server
2）、jack-admin kill-server
3）、jack-admin list-server
4）、jack-admin uninstall-server
5）、mm -j32 showcommands &> mm.out
6）、jack-admin install-server jack-launcher.jar jack-server-4.8.ALPHA.jar
7）、jack-admin dump-report
8）、jack-admin dump-re五、本人亲自测试ok，成功编译。
