1、把依赖版本号统一放到properties里面 例如下面的版本需要改下放到<properties></properties>中

<dependency>
                <groupId>org.apache.zookeeper</groupId>
                <artifactId>zookeeper</artifactId>
                <version>3.5.6</version>
            </dependency>
            <dependency>
                <groupId>com.101tec</groupId>
                <artifactId>zkclient</artifactId>
                <version>0.10</version>
            </dependency>

2、类似以下这种

<configuration>
                   <source>1.8</source>
                   <target>1.8</target>
                   <encoding>UTF-8</encoding>
               </configuration>

统一用jdk.version、project.build.sourceEncoding
