编译tomcat-redis-session-manager项目【也可以直接从百度云下载】
1.git clone git@github.com:jcoleman/tomcat-redis-session-manager.git
2. cd tomcat-redis-session-manager && vi pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

</project>
3.执行mvn clean 和mvn install 将编译好的代码打包为：tomcat-redis-session-1.0-SNAPSHOT.jar，将tomcat-redis-session-1.0-SNAPSHOT.jar、jedis-2.7.2.jar、commons-pool2-2.0.jar 三个jar包分别放在tomcat8080和tomcat8060实例下的lib目录下。
4.修改配置/root/tomcat/tomcat8060/conf/context.xml、/root/tomcat/tomcat8080/conf/context.xml 配置redis session 共享
cd /root/tomcat/tomcat8060/conf vi context.xml
注意 Redis 一定要配置密码的！

问题：
1.git clone git@github.com:jcoleman/tomcat-redis-session-manager.git 不成功
