We all know that Maven is essentially a plug-in framework, and its core does not execute any specific build tasks. All these tasks are handed over to the plug-in for completion, for example, the source code is compiled by Maven-compiler-plugin. Further, each task corresponds to a plug-in target (GOAL), and each plug-in has one or more targets. For example, the compile target of
Requirements:
When Maven compiles the project, the amount of code, that is, the number of files in the project, the number of lines of code, including the Java files and configuration files Two, where the configuration file (SQL, XML, properties) lines/4 processing.
