Use myeclipse to add a Maven-Project project. Before that, you may need to configure your m2eclipse
1. Configure Maven to your own installed version.

2. Set user settings
Of course, you can also modify the default directory of the repository and enter the maven installation directory CONF/setting. xml.
In the <Settings> node
Add: <localrepository> D:/myrepository </localrepository>.

After finishing the Pom. xml file, run project-right-click-run-Maven install
After downloading the jar package, you can write the code after the test is successful.
