Maven Error cached in Local Repository error

Question

My Maven Clean Install is success but my pom.xml still shows compilation error.

The Error is Failure to transfer org.apache.maven.plugins:maven-resources-plugin:pom:2.5 from http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.apache.maven.plugins:maven-resources-plugin:pom:2.5 from/to central (http://repo.maven.apache.org/maven2): NullPointerException

I have Tried restarting eclipse and Updating the Maven Projects Still the Complation error is not going.

Any Resolution for this?

Answer 1

Please try deleting the artifact from your local maven repository and running the maven build again. It should try downloading the latest updated artifact. Generally the caching issue happens because of the .lastUpdated file created in your artifact's directory in local repo.

Answer 2

1. Run maven with enforce an update:

   mvn -U clean install or mvn -U verify

2. If that doesn't work, delete the artifact from your local maven repo:

   rm -R ~/.m2/repository/org/apache/maven/plugins/maven-resources-plugin/

   and run maven again (mvn clean install or mvn verify).
