Maven not downloading dependencies in Eclipse

Sometimes there is an error downloading a dependency - eg. some files are downloaded but the actual JAR is missing from the local Maven repository.

In this case I had to delete the whole folder of the problematic dependency in the local maven repository. Only then did Maven update work (Right-click on the project and select Project > Maven > Update Project.... )

I got the same problem and this is how i solved. :

1. Right click your project, choose Run As -> Maven install. Observe the output console to see the installation progress. After the installation is finished, you can continue to the next step.

2. Right click your Spring MVC project, choose Maven -> Update Project.

3. Choose your project and click OK. Wait until update process is finished.
4. The error still yet, then do Project->Clean and then be sure you have selected our project directory and then do the follow Project->Build.

Solution 1:

Set correct proxy:

<proxy>
    <id>optional</id>
    <active>false</active>
    <protocol>http</protocol>
    <username></username>
    <password></password>
    <host>172.27.171.91</host>
    <port>8080</port>
</proxy>

Solution2 :

just delete

lastupdated extension files from folder

and try updating maven.

[Most of the times this solution will work]
