Question

Solutions Tried:

Updated project: not able to download from REPO of maven.

Tried putting perticular jar in that folder of .m2 repo.

Can provide references if you want.

Solution 1

Seems your settings.xml file is missing your .m2 (local maven repo) folder.

When using eclipse navigate to Window -> Preferences -> Maven -> User Settings -> Browse to your settings.xml and click apply.

Then do maven Update Project.

Solution 2

Right Click on Project go to -> Maven -> Update project ->select Force update project check box and click on Finish.

Solution 3

On windows:

1. Remove folder from C:\Users\USER.m2
2. Close and open the project or force a change on file: pom.xml for saving :)

Solution 4

If a download fails for some reason Maven will not try to download it within a certain time frame (it leaves a file with a timestamp).

To fix this you can either

• Clear (parts of) your .m2 repo
• Run maven with -U to force an update

I have faced the same issue. Try declaring missing plugin in the conf/settings.xml.

<build>
    <pluginManagement>
      <plugins>
        <plugin>
          <artifactId>maven-resources-plugin</artifactId>
          <version>2.6</version>
        </plugin>           
      </plugins>
    </pluginManagement>   
</build>
