Answer 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.

Answer 2

Step 1 : Check the proxy configured in eclipse is correct or not ? (Window->Preferences->General->Network Connections).

Step 2 : Right Click on Project-> Go to Maven -> Update the project

Step 3: Run as Maven Install.

Answer 3

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>

Answer 4

Tried everything. I deleted m2e and installed m2e version 2.7.0. Then deleted the .m2 directory and force updated maven. It worked!

Answer 5

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 :)

Answer 6

This fixed the same issue for me: My eclipse is installed in /usr/local/bin/eclipse

1) Changed permission for eclipse from root to owner: sudo chown -R $USER eclipse

2) Right click on project/Maven right click on Update Maven select Force update maven project
