在Eclipse上执行tomcat7:run错误解决方法

如果在JAVA EE IDE上运行tomcat7：run的时候出现以下错误。可以参照下方的解决方案

[ERROR]Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project Resrauran

[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

[ERROR] -> [Help 1]

解决方法：

右键点击项目，在弹出的菜单中选择properties：

点开后，选择Maven项目中的Project Facets,有可能不会显示以下内容，应该会出现一行蓝字（已经点过了，所以就没办法截屏了），点击一下就会出现如下内容，再点击Runtimes,勾选Apache Tomcat v7.0（或其他版本），然后点击ok就解决了：

如果没有Apache Tomcat v7.0,就点击“new"，并选择下载在本地的Tomcat版本相对应的版本号。并且点击"Next”:

最后选择路径和JRE就解决了。
