Maven dependency Error--Download failure problem solution

Problem Description:

　　The container ' Maven Dependencies ' references non existing library ' ${groupid}/${artifactid}-${version}.jar '

Solution:

The problem is often caused by network problems during the download dependency process. At this point we have started to download the dependency code, but the download failed, the native repository will be in the ${maven_repo}/${groupid}/${artifactid}/${version} path under the *.lastupdated file; *.lastupdated is really hateful, next time the download due to its presence maven will not download again.

1. Open the directory where the local repository is located, find the *.lastupdated through the Windows folder search function, and then delete all the found files

2. Re-Maven Update Project,

1. Tick on force Update of Snapshots/releases when operating in eclipse

2. If you add the-u parameter to the command line operation

In general, the above method solves the problem.
