dubbo-admin 2.5.4 编译和部署
转自: http://blog.51cto.com/morrowind/1933538
前言：
公司比较奇葩，应用服务器用的还是老版本的resin、jboss这些。由于原有dubbo-admin无法访问，就想用tomcat重新部署套。官网dubbo.io提供的下载地址已经无法下载，那就用源码编译吧。
环境：
系统：linux
maven：3.5.0
java:1.7.0_80
问题：
git clone https://github.com/alibaba/dubbo.git
git完源码后，以为按照github上的说明一步一步来就可以编译成功，其实不然。官方文档没有说明java版本，而说明的maven版本是2.2，mvn install 一直报错，加了-X参数后看到一些详细信息，但搜索到的都是说java版本问题。
解决：
于是将java版本从1.6-1.8都试了，但还是一样的错误……无果，于是找了位开发，让其帮build下，结果……居然成功了，但启tomcat时又是各种错，就问了下开发的编译环境：
maven：3.5+
java:1.8+
这次查tomcat日志信息确实是java版本的问题了，但不是tomcat使用的java版本，而是build dubbo时使用的java版本问题，build dubbo时不能使用java1.8+的版本。于是使用java1.7 自己重新build了下，在放到tomcat中运行，可以正常访问了
插曲：
看到网上有人说直接到duboo-admin目录下mvn package -Dmaven.skip.test=true 就可以打包成功，但我这报错，错误信息如下：

想着应该是没有编译dubbo的问题导致缺少依赖jar，于是到dubbo主目录，将dubbo全编译了下，看到成功后，在dubbo-admin/target 下就生成了需要的dubbo-admin-2.5.4-SNAPSHOT.war文件。这时可将dubbo-admin-2.5.4-SNAPSHOT目录内的文件直接放到tomcat的ROOT目录下，修改dubbo.properties文件内的zookeeper

dubbo.registry.address=zookeeper://ip_1:2181?backup=ip_2:2181,ip_3:2181dubbo.admin.root.password=rootdubbo.admin.guest.password=guest |
验证：
浏览器访问tomcat地址，用root或guest登录，页面如下
