#Maven打包遇到的一些问题

## 1.将依赖打成一个包
参考这篇

## 2.Fatal error compiling: 无效的目 标版本： 1.7 -> [Help 1]

因为是在cmd中执行，然后maven依赖jdk，我的环境变量中将JAVA_HOME写死，指导了jdk1.6版本。而这个项目需要1.7版本，在POM文件的编译插件中

<plugin>
       <artifactId>maven-compiler-plugin</artifactId>
       <version>3.1</version>
       <configuration>
         <source>1.7</source>
         <target>1.7</target>
       </configuration>
     </plugin>

 将版本设置为1.7就会报上面的错误。重新指定环境变量JAVA_HOME指到支持1.7以上的JDK就可以了
