[WARNING] The requested profile "nexus" could not be activated because it does not exist.

　　

2 仔细检查Maven的.setting文件，自己嵌套了两层profiles，注释掉多余的就可以了。

	<profiles>
		<!-- profile | Specifies a set of introductions to the build process, to
			be activated using one or more of the | mechanisms described above. For inheritance
			purposes, and to activate profiles via <activatedProfiles/> | or the command
			line, profiles have to have an ID that is unique. | | An encouraged best
			practice for profile identification is to use a consistent naming convention
			| for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey',
			'user-brett', etc. | This will make it more intuitive to understand what
			the set of introduced profiles is attempting | to accomplish, particularly
			when you only have a list of profile id's for debug. | | This profile example
			uses the JDK version to trigger activation, and provides a JDK-specific repo. -->
