1. Find pom.xml, right click and select Run As >> Maven build...
Enter "dependency:copy-dependencies" in the Goals box in the figure above, and then click "Run". The initial generation may take a while longer, and the console may run for a while.
When "BUILD SUCCESS" appears on the console, it means the build is successful.
In the root directory "targed/dependency" of the current project, you can view all the generated dependent jar packages.
