Jack-Server(二) aosp 编译过程中Jack server SSL error 错误解决方法

rk3288 — android 7.1 JDK安装及 jack-server配置

一.jack-server 配置

1.1.Android7.1 系统使用 jack-server 作为 java 代码编译器，在编译过程中可能会遇到以下类似的错误:

Jack server already installed in "/home/user/.jack-server"
Communication error with Jack server (1), try 'jack-diagnose' or see Jack server log
Communication error with Jack server 1. Try 'jack-diagnose'
Communication error with Jack server 1. Try 'jack-diagnose'

此错误是由于 jack-server 本身编译器限制，同一个网络端口号不能多个用户同时使用

即多个用户在同一个服务器上协同开发过程中，编译 Android7.1 时，需要配置各自使用不同的网络端口号　　

1.2.jack-server 的两个配置文件(user 为对应用户的用户名)，决定了它所使用的端口号

1 2	`/home/user/.jack-server/config.properties` `/home/user/.jack-settings`

这两个配置文件需要配置两个端口号，分别为服务端端口号，及客户端端口号，两个配置文件中的端口号要匹配　

jack.server.service.port=8074
jack.server.admin.port=8075
及 
SERVER_PORT_SERVICE=8074
SERVER_PORT_ADMIN=8075

配置步骤如下: 确保两个配置文件存在，并且权限设置为 0600

1 2	`chmod` `0600` `/home/user/.jack-server/config.properties` `chmod` `0600` `/home/user/.jack-settings`

1.3. 文件 .jack-settings 文件目录 .jack-server

1.4. .jack-server/config.properties

修改端口号，请更改 service port 及 admin port 为其他端口号，两个配置文件里的端口号需要匹配示例如下：　

jack.server.service.port=8090
jack.server.admin.port=8091
及 
SERVER_PORT_SERVICE=8090
SERVER_PORT_ADMIN=8091

若两个配置文件不存在请参照以下文本新建这两个配置文件 config.properties 文件示例如下(端口号需按实际修改)

.jack-settings

# Server settings
SERVER_HOST=127.0.0.1
SERVER_PORT_SERVICE=8090
SERVER_PORT_ADMIN=8091
  
# Internal, do not touch
SETTING_VERSION=4

.jack-server/config.properties

jack.server.max-jars-size=104857600
jack.server.max-service=4
jack.server.service.port=8090
jack.server.max-service.by-mem=1\=2147483648\:2\=3221225472\:3\=4294967296
jack.server.admin.port=8091
jack.server.config.version=2
jack.server.time-out=7200

1.5. prebuilts/sdk/tools 重启 jack-server ./jack-admin kill-server && ./jack-admin start-server

二 .Android 7.1 编译过程中Jack server SSL error 错误解决方法

2.1.使用的环境是ubuntu 16.04 编译大概率会出现jack server 跑不起来然后抛一个类似这样的错误

如下：

[ 10% 538/4980] Ensuring Jack server is installed and started

cy
ninja: build stopped: subcommand failed. 
22:32:18 ninja failed with: exit status 1
build completed failed

2.2.原因就是编译时用的是open-jdk 8u292，默认禁用了TLSv1, TLSv1.1，从/etc/java-8-openjdk/security/java.security中取消TLSv1, TLSv1.1 禁用，修改前:

修改后:

jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA, \
 
DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL, \
 
include jdk.disabled.namedCurves 

2.3./prebuilts/sdk/tools/ 目录下执行 ./jack-admin kill-server && ./jack-admin start-server 成功
