Package jar package separately from lib dependencies
Method 1: Complete separation of project and dependency
maven-jar-plugin is responsible for generating jar files (how dependencies are not included in the jar file) and configuring related content for the jar file's files; the maven-dependent-plugin plugin is used to copy the project's runtime dependencies to the specified directory at build time.
When deploying a project, the produced jar file must be in the same directory as the lib dependency package.

</build>Method 2: Partial dependencies are entered into the jar file
-
maven-jar-pluginPlugin is used to generate the main JAR file and configure the relevant information in the file; -
maven-shade-pluginPlugins are used to package some specific dependencies (such as common and coo) into the main JAR file, and are usually used to create a "uber JAR" (i.e., a JAR containing all dependencies); -
maven-dependency-pluginPlugins are used to copy all runtime dependencies except specified dependencies (such as common and coo) to the lib/ directory during the build process;
Because maven-jar-plugin will generate a dependency-free jar file, it can be deleted if it is not needed. The maven-antrun-plugin plugin is used to perform some additional tasks, such as deleting unwanted JAR files.
When deploying a project, the produced jar file must be in the same directory as the lib dependency package.
