ERROR:

Could not calculate build plan: Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.6
Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.6

Solutions Tried:

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

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

If you are using jenkins and Sonatype Nexus repository :

Update pom.xml :

 <build>
 <plugins>
     <plugin>
         <artifactId>maven-resources-plugin</artifactId>
         <version>3.3.1</version>
     </plugin>
 </plugins>

Update the Maven version in Jenkins --> Manage Jenkins --> Tools : Maven verion 3.2.5
Login to Jenkins server and remove .m2 folder ( /jenkins/.m2/)

Login to Sonatype and check whether Proxy URL is http or https. Use these URLs only for Maven Proxy : https://repo.maven.apache.org/maven2/ -- OR--
https://repo1.maven.org/maven2/

Run the mvn commands as Admin on console.

What worked for me was:

mvn -Dhttps.protocols=TLSv1.2 install

Right click on your project under Package Explorer > Maven > Update Project > Select the checkbox that reads "Force updates of Snapshot/Releases" > Click on OK

This way you don't have to search around for your maven's settings.xml and if the cause is something else eclipse will automatically handle it whatever it may be. Expected path for user settings XML is shown by eclipse under: Window > Preferences > Maven > User Settings > User Settings (it is most likely, greyed out).

This issue is happening due to change of protocol from http to https for central repository. please refer following link for more details. https://support.sonatype.com/hc/en-us/articles/360041287334-Central-501-HTTPS-Required 

In order to fix the problem, copy following into your pom.ml file. This will set the repository url to use https.

<repositories>
        <repository>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
            <id>central</id>
            <name>Central Repository</name>
            <url>https://repo.maven.apache.org/maven2</url>
        </repository>
    </repositories>
    <pluginRepositories>
        <pluginRepository>
            <releases>
                <updatePolicy>never</updatePolicy>
            </releases>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
            <id>central</id>
            <name>Central Repository</name>
            <url>https://repo.maven.apache.org/maven2</url>
        </pluginRepository>
    </pluginRepositories>

I had exactly the same error. My network is an internal one of a company. The proxy has been disabled from the IT team so for that we do not have to enable any proxy settings. I have commented the proxy setting in settings.xml file from the below mentioned locations C:\Users\vijay.singh.m2\settings.xml This fixed the same issue for me

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

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

I had exactly the same error. My network is an internal one of a company. I downloaded neon-eclipse for java developpers. These steps worked for me:

1- I downloaded a VPN client on my PC to be totally blinded from the network. Shellfire I used. Use free account and connect to Shellserver.

2- Inside the windows firewall, I added incoming rule for Eclipse. Navigate to where eclipse exe is found.

3- Perform Maven Update project.

Then the project was able to fetch from the maven repository.

hope it helps.

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>
