Android JACK 编译错误SSL error when connecting to the Jack server

背景

之前编译好好，今天居然遇到了这样子的问题。还以为是和之前一样，Android7.0 配置JACK支持多用户同时编译。

结果不是：

/bin/bash -c "(prebuilts/sdk/tools/jack-admin install-server prebuilts/sdk/tools/jack-launcher.jar prebuilts/sdk/tools/jack-server-4.11.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-4.11.ALPHA.jar 4.11.ALPHA 2>&1 || exit 0 ) && (prebuilts/sdk/tools/jack-admin update jack prebuilts/sdk/tools/jacks/jack-4.32.CANDIDATE.jar 4.32.CANDIDATE || exit 47 )"
Jack server already installed in "/home/xx/.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'

做法1

也可以用降级的做法来实现，这里以使用的OPENJDK为例。

将JDK降级为允许使用的版本，可以在这里下载安装：https://www.openlogic.com/openjdk-downloads

我是将 JDK8_295 降级为 JDK_272即可。

• Java Version : 8
• Operating System : Linux
• Architecture : x86 64-bit
• Java Package : JDK

卸载 当前的JDK：

sudo apt-get purge -y openjdk* 
sudo apt-get purge -y icedtea-* openjdk-*

## 检查是否卸载干净
dpkg --list | grep -i jdk

通过deb包安装JDK8：

## 下载链接
wget https://builds.openlogic.com/downloadJDK/openlogic-openjdk/8u272-b10/openlogic-openjdk-8u272-b10-linux-x64-deb.deb
## 安装
sudo dpkg -i openlogic-openjdk-8u272-b10-linux-x64-deb.deb

做法2

修改 prebuilts/sdk/tools/jack-admin即可。

以及 vi ~/.jack-server/config.properties ~/.jack-settings，将port改掉。

可以参考：Android7.0 配置JACK支持多用户同时编译

附录：报错原因

最近也有人提这个问题，而且说得很详细：就是JDK 版本的问题引起的。
