首先感谢学员提供线索和链接，我这边做一个总结，针对近期的编译android 8.1突然2021年5月1号左右突然jack server一直报错，网络百度都是些什么修改端口等，根本无法解决，这边按照jack 命令导出报告的日志打印如下：

Ensure Jack server is installed and started
FAILED: /bin/bash -c "(prebuilts/sdk/tools/jack-admin install-server prebuilts/sdk/tools/jack-launcher.jar prebuilts/sdk/tools/jack-server-4.8.ALPHA.jar 2>&1 || (exit 0) ) && (JACK_SERVER_VM_ARGUMENTS=\\"-Dfile.encoding=UTF-8 -XX:+TieredCompilation\\" prebuilts/sdk/tools/jack-admin start-server 2>&1 || exit 0 ) && (prebuilts/sdk/tools/jack-admin update server prebuilts/sdk/tools/jack-server-4.8.ALPHA.jar 4.8.ALPHA 2>&1 || exit 0 ) && (prebuilts/sdk/tools/jack-admin update jack prebuilts/sdk/tools/jacks/jack-2.28.RELEASE.jar 2.28.RELEASE || exit 47; prebuilts/sdk/tools/jack-admin update jack prebuilts/sdk/tools/jacks/jack-3.36.CANDIDATE.jar 3.36.CANDIDATE || exit 47; prebuilts/sdk/tools/jack-admin update jack prebuilts/sdk/tools/jacks/jack-4.7.BETA.jar 4.7.BETA || exit 47 )"
Jack server already installed

SSL error when connecting to the Jack server. Try 'jack-diagnose'

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

这里的首先我这边一共提出2中解决方案：
1、直接关闭jack方式，即压根我们就不使用jack来编译

把 原来的 make命令变成 --》 make ANDROID_COMPILE_WITH_JACK=false

这种方式就是不管什么原因jack导致无法编译，我就关闭jack，不使用总可以吧，相当于躲避规避

2、如果还想使用jack，那这种解决方法就得感谢我的学员提供线索了
原因：
问题出现的原因是jdk自行更新新版本，新版本的说明为

释放说明 https://java.com/en/download/help/release_changes.html

释放日期 https://java.com/en/download/help/release_dates.html

大概就是java这个日期有更新，并且有如下release Note：
Other notes: Disable TLS 1.0 and 1.1
TLS 1.0 and 1.1 are versions of the TLS protocol that are no longer considered secure and have been superseded by more secure and modern versions (TLS 1.2 and 1.3).
These versions have now been disabled by default. If you encounter issues, you can, at your own risk, re-enable the versions by removing “TLSv1” and/or “TLSv1.1” from the jdk.tls.disabledAlgorithms security property in the java.security configuration file.
See JDK-8202343

大概就是不支持这种不安全的TLS 1.0 and 1.1，如果要开启就要去jdk.tls.disabledAlgorithms把他给去除

具体做法：
去/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/security/java.security 文件中寻找到jdk.tls.disabledAlgorithms的config
你们应该如下：

所以这里我们要解决就删除这两个，编辑命令就

sudo vi /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/security/java.security 

删除后进行wq保存
最后记得把系统重启一下：

sudo reboot

然后再进行make：
