There are 3 plugins for generating to create a JAR-File in maven:

• maven-jar-plugin
• maven-assembly-plugin
• maven-shade-plugin

maven-jar-plugin:This plugin provides the capability to build and sign jars.But it just compiles the java files under src/main/java and /src/main/resources/.It doesn't include the dependencies JAR files.

<!--exclude all xml files from the jar-->

/*
 * Test program to show how to remove warnings from generic array construction.
 * First step:  Remove any raw types, by adding <?> as needed.
 * Second step:  Add a cast if needed, to the specific non-wildcard type.
 * Third step:  Suppress "unchecked" warnings on the cast.
 * The point of the first step is to remove the "rawtypes" warning
 * cleanly, without resorting to an additional warning suppression.
 * Note that every use of @SuppressWarnings should have a comment.
