Now, assuming you have finished coding your Java project and compiled the same, it is time to create a JAR file.

  • The first step for creating JAR file is to ensure cleansing any previous build artifacts before packaging them as a Maven project. This can be done using mvn clean which removes all the previously generated files from ./target folder.

  • mvn package would create a new package at ./target folder.

Alternately, we could combine cleaning and package creation as one step by typing mvn clean package. You would get a new JAR file created.
