Eclipse Java EE工程报错：JAX-RS (REST Web Services) 2.0 can not be installed、JAX-RS (REST Web Services) 2

导入了一个Java EE SDK7 里面的工程，Eclipse报错

JAX-RS (REST Web Services) 2.0 can not be installed : One or more constraints have not been satisfied. message-board line 1 Maven Java EE Configuration Problem

JAX-RS (REST Web Services) 2.0 requires Java 1.6 or newer. message-board line 1 Maven Java EE Configuration Problem

提示requires Java 1.6 or newer，看了下Properties -> Project Facets -> Java配的是1.8没错，又看了看提示是Maven Java EE Configuration Problem相关问题，于是想到可能与maven-compiler-plugin相关，在该插件添加以下选项后解决

<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
