A required class was missing while executing org.apache.maven.plugins:maven-jar-plugin:3.2.0:jar

Question

When I run mvn clean install on my maven project, It is giving me the below error

Answer 1

You can run the maven build command with argument -X to enable debug logging.

Normally the class MavenArchiveConfiguration is loaded from maven-archiver , which is a dependency of the maven-jar-plugin . These dependencies are managed in the plugins' pom file, and loaded by the maven build process from that pom.

When i locally modify the pom file for this plugin (remove all dependencies ) then i can reproduce this error message. This leads me to believe there is something wrong with your downloaded copy.

As a solution you can remove the contents of .m2\repository\org\apache\maven\plugins\ and .m2\repository\org\apache\maven\maven-archiver and try your build again, then all correct plugin files and dependencies should be downloaded again from maven central.

Then you should find the jar+pom files for the plugin + dependency in your local.m2 folder: .m2\repository\org\apache\maven\plugins\maven-jar-plugin\3.2.0 and .m2\repository\org\apache\maven\maven-archiver\3.5.0 . You can also look in those folders for the _remote.repositories file to check for any download issues.

You can also check if you have any custom pluginRepositories configured that may be providing you with corrupt jar/pom files. You can see your entire pom file by running mvn help:effective-pom .

Normally that should include the following from the super pom :

  <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>

More extreme measures could be to download a newer version of maven, or clear your entire local .m2 (create a backup if you have important files in there).

Those would be the places to look to resolve this issue.
