Getting started with maven

Recently, I learned how to use Maven on the MOOC online, and recorded the approximate content as follows:

 

Directory Structure:

 

src
  --main
     --java <- build source code structure (including package name) in this directory
  --test
    --java <- Test code to build source code in this directory
  --resource

 Common commands:

 

• mvn compile compile source code
• mvn test compiles and runs test code
• mvn package packages the class files of the source code
• mvn clean clears all the results of the previous mavn execution (that is, deletes the target directory under the same level of src)
• mvn install compiles and packages the source code and saves the packaged package to the local repository
