Method 1: The two-day use of MAVEN in building an application, because project is very large, there are more than 700 pom.xml files, and even more depressing is that in many pom.xml files are individually specified in the repository URL, I need to assign the URLs of these repositories uniformly to the Nexus local Central library. Manually change the file configuration is a bit less practical, so Google a bit, find the bulk of the replacement file content of a good way, the command structure is
