How to solve maven 2.6 resource plugin dependency?

Question

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.

Can provide references if you want.

Looks like proxy/firewall issue? – khmarbaise Jul 09 '15 at 13:28 — khmarbaise, Jul 09 '15 at 13:28

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.

is Pom.xml file same as setting.xml file? POM.xml file contains all the dependencies. should i select POM.xml file? – Jay Dangar Dec 28 '18 at 05:24
no pom.xml file belongs to project, settings.xml is a part of maven – Menuka Ishan Nov 26 '19 at 06:25

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>

On windows:

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

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

For the force update there is an option in eclipse that will do, right ? – spt025 Jul 09 '15 at 11:46
Okay the same error persists even after we provide force update.I'm using eclipse. – spt025 Jul 09 '15 at 11:47
I'm not sure how Eclipse handles this, could you run `mvn install -U` from the command line? – Pim Verkerk Jul 09 '15 at 11:50
Installing Maven can be done with this [guide](https://maven.apache.org/install.html) an alternative to Maven would be [gradle](https://gradle.org/) – Pim Verkerk Jul 09 '15 at 13:07

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

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 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>

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.

what incoming rule you added for Eclipse? – Suresh Jun 15 '18 at 09:58 — Suresh, Jun 15 '18 at 09:58

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

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).

improve your answer with more details about the solution. The project you deleted were the one with the issue or another that caused it? After deleting, what were the next steps: you recreated the project? you just build it again? The current state of the answer is not enough to solve the problem! With more details is easier to understand! – Felipe Bonfante May 19 '22 at 12:22

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/
