Maven error - resolving dependencies

I'm not very familiar with maven and I'm struggling with this error message when running a maven compile:

[ERROR] Failed to execute goal on project myProject: Could not resolve dependencies for project myProject:1.0: Failure to find weka:weka:jar:3.7.1-beta in 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 -> [Help 1]

The pom looks like this:

It was Friday... I mixed up two maven projects. Thanks a lot for your help!

If you can upgrade, later versions of weka are in maven central.

Alternatively, as a last resort if you can't find the versions you need in a maven repo somewhere, you could download the jars you need from the weka site, and put them in your local repository, something like this:

mvn install:install-file -Dfile=weka-3.7.1-beta.jar -DgroupId=weka -DartifactId=weka -Dversion=3.7.1-beta -DgeneratePom=true

First part of the message means that one of your (transitive) dependency is missing in your accessible repositories.

Second part means that it is not the first time this request has been made, so unless you un-blacklist it (with -U in your command for instance), Maven will not try to find it again on the remote repositories.
