Adding the facet, wont let me apply it since it says I need Java 1.7

Delete the .projectfile and banish it from your source control. Instead of using Import -> Existing Project, use Import -> Maven project, and let m2e configure your Eclipse project.
删除该.project文件并将其从源代码管理中删除。不使用导入 -> 现有项目，而是使用导入 -> Maven 项目，并让 m2e 配置您的 Eclipse 项目。

If the intention is to just get rid of these errors then you can simply right click on the errors in the "Marker View" and click delete.
如果只是想摆脱这些错误，那么您只需右键单击“标记视图”中的错误，然后单击删除即可。

I know you can't change your 1.6 JDK, but the following solution might help other people:
我知道您无法更改 1.6 JDK，但以下解决方案可能对其他人有所帮助：
In my case, I have both JDK 1.6 and 1.7. I've tried several suggested solutions without any success.
就我而言，我同时拥有 JDK 1.6 和 1.7。我已经尝试了几种建议的解决方案，但没有任何成功。
Hence, in my pom.xml I changed from jdk 1.6 to jdk 1.7:
因此，在我的 pom.xml 中，我从 jdk 1.6 更改为 jdk 1.7：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.0</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
Using jdk 1.7 worked for me, although in my facets is setted the 1.6 (because my intention was use jdk 1.6).
使用 jdk 1.7 对我有用，尽管在我的方面设置了 1.6（因为我的意图是使用 jdk 1.6）。
