How to solve the failure to transfer error when using Maven

Use Maven in eclipse to connect to the nexus private server.

After adding the dependency, it is always reported that the added dependency JAR file cannot be found, but the JAR file can be found in the nexus library, but cannot be found in the local Maven library, so I deleted the folder corresponding to this dependency in the local library, and then executed update dependencies in eclipse. Solved the problem successfully!

Right-click Project> Maven> Update dependencies.

The cause is that the local library requests the JAR file from nexus. If the private server does not exist, download it online. If the network speed is too slow, this error is reported if the download time exceeds the time limit set by Maven.
