maven-dependency-plugin could not be resolved

Question

I am trying to build my project using maven but keep on getting following error.

[ERROR] Plugin org.apache.maven.plugins:maven-dependency-plugin:3.1.1 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-dependency-plugin:jar:3.1.1: The following artifacts could not be resolved: org.apache.maven.plugins:maven-dependency-plugin:pom:3.1.1 (absent): Could not transfer artifact org.apache.maven.plugins:maven-dependency-plugin:pom:3.1.1 from/to nexus-thirdparty (https://nexus.audatex.com/nexus/content/repositories/thirdparty): status code: 401, reason phrase: Unauthorized (401) -> [Help 1]

I have tried deleting .m2/repository and again did mvn clean install but still the same error is coming.

Any advice is helpful. Thanks.

In case this happens also with other artifacts you try to fetch from this Nexus, please check your maven settings .m2/settings.xml if there are all necessary credentials for your nexus server present. Alternatively they could be set in the pom.xml, but that would be a security issue.

In case there are present it could also possibly be that you just don't have the right permissions onto the repository "thirdparty" of your nexus server. I would recommend to validate this with your administrator.

To give you a sample of what you should be looking for:

<servers>
    <server>
        <id>internal-company-repository</id>
        <username>demo-user</username>
        <password>dummy-password</password>
        <privateKey>${user.home}/.ssh/bael_key</privateKey>
        <passphrase>dummy-passphrase</passphrase>
        <filePermissions>664</filePermissions>
        <directoryPermissions>775</directoryPermissions>
        <configuration></configuration>
    </server>
</servers>

Note that the id here needs to match the id of the <repository> attribute in your pom.xml
