编译OSS Android SDK出错，javax.net.ssl.SSLException: Received fatal alert: protocol_version

在编译OSS Jar时按照官方步骤操作如下：

# clone工程
$ git clone https://github.com/aliyun/aliyun-oss-android-sdk.git

# 进入目录
$ cd aliyun-oss-android-sdk/oss-android-sdk/

# 执行打包脚本，要求jdk 1.7
$ ../gradlew releaseJar

# 进入打包生成目录，jar包生成在该目录下
$ cd build/libs && ls

 

结果编译报错：

root@host:/home/develop/aliyun-oss-android-sdk/oss-android-sdk# ../gradlew releaseJar

这是因为 jdk1.7 默认使用的是TLS1.0，

使用  curl -v https://services.gradle.org  可以看到网站使用的是 TLS1.2

解决办法 使用jdk1.8编译
