Maven not using the local repo

Question

I'm using maven without m2e, my mvn install is failing because a plugin is not available anymore on maven central. I'm working with an old pom.xml dating from 2008 and must uses maven-cdk-plugin version 3.3.3.Final.

Since it was not available anymore I took it on someone else computer and putted it in my .m2 local repo. .m2\org\richfaces\cdk\maven-cdk-plugin\3.3.3.Final

however I'm still getting this error.

[ERROR] Plugin org.richfaces.cdk:maven-cdk-plugin:3.3.3.Final or one of its depe
ndencies could not be resolved: Failed to read artifact descriptor for org.richf
aces.cdk:maven-cdk-plugin:jar:3.3.3.Final: Failure to find org.richfaces.cdk:mav
en-cdk-plugin:pom:3.3.3.Final in http://uk.maven.org/maven2 was cached in the lo
cal repository, resolution will not be reattempted until the update interval of
UK has elapsed or updates are forced -> [Help 1]

Why would he want to check maven2, it's inside my local repo? D:

thanks

Answer 1

You must install that jar with install plugin`.

mvn install:install-file -Dfile=[jar] -DgroupId=org.richfaces.cdk \
-DartifactId=maven-cdk-plugin -Dversion=3.3.3.Final -Dpackaging=jar

Maven will keep the structure and generate the things it needs.

Try mvn clean install -o to not look in internet for dependencies.

Also echo $M2_REPO. it should point to the .m2.

The first thing is that what you mentioned the maven-cdk-plugin has never been on Maven Central cause it's available via richfaces repository so you have to configure to use the richfaces repository as well. This results in using a repository manager like Archiva, Artifactory or Nexus (alphabetical order). So you need to configure to use the richfaces repository.

See here: https://community.jboss.org/wiki/MavenRepository how to do so.

Here you can see that the plugin exists in this repository https://repository.jboss.org/nexus/

One very important thing. Any artifact which is in Maven Central will never be deleted afterwards cause otherwise this would break builds all over the world.
