I had same issue, the problem is with properties. Check your JavaSE version in your project, it will be displayed beside JRE System Library folder in your project. If it is 1.5, then it will throw an error. Most probably you will have a updated version, so check the version and update it. I have updated it below based on your code.
我有同样的问题，问题出在属性上。检查您项目中的 JavaSE 版本，它将显示在您项目中的 JRE System Library 文件夹旁边。如果是 1.5，那么它会抛出一个错误。很可能你会有一个更新的版本，所以检查版本并更新它。我已经根据您的代码在下面更新了它。
<properties>
<maven.compiler.source>1.6</maven.compiler.source>
<maven.compiler.target>1.6</maven.compiler.target>
</properties>

I think you have wrong your pom.xml:
我认为你的 pom.xml 错了：
<properties>
<maven.compiler.source>6</maven.compiler.source>
<maven.compiler.target>1.6</maven.compiler.target>
</properties>
change to:
改成：
<properties>
<maven.compiler.source>1.6</maven.compiler.source>
<maven.compiler.target>1.6</maven.compiler.target>
</properties>
Now depending if you are using the command line use:
现在取决于您是否使用命令行使用：
mvn clean compile
mvn 干净编译
or either way(eclipse ide)
或者任何一种方式（eclipse ide）
Right click on project Run with maven>build>Goal (compile)
右键单击项目 Run with maven>build>Goal（编译）
