Resolves a non-local third-party package issue with the Maven search that comes with eclipse

The recent use of the Maven plugin in Eclipse found that when adding a third-party package to a pom.xml file, it was particularly inconvenient and confusing to query for non-native jar packages. I remember installing the Maven plugin myself in the early version of Eclipse, and it took me half an hour to study it, and found out that the plug-in that eclipse comes from doesn't download the third-party Package index locally by default, so it won't be searchable. You can download and use the following method as follows

1. Turn on MAVEN, Windows-Preferences, select

2. Open the Maven-maven repositories view, Orther, Windows--show views

3. Right-click on the global repositories in the MAVEN repositories view and select Update Index

4. Eclipse may be a bit of a card when downloading, wait a few minutes.
