Maven settings: Need an explaination for Beginer MVN User.

[H Paul]

Basically, I used Eclipse Indigo to create a Camel Web using MVN.

I got the error on the pom.xml and not sure what it really meant in terms of setting that I need to do:

Failure to transfer org.apache.maven.plugins:maven-war-plugin:pom:2.1.1 from http://repo1.maven.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-war-plugin:pom:2.1.1 from/to central (http://repo1.maven.org/maven2): null to http://repo1.maven.org/maven2/org/apache/maven/plugins/maven-war-plugin/2.1.1/maven-war-plugin-2.1.1.pom

1M Thanks.

I would ensure something like your firewall is not blocking Maven from downloading jars.

Another thing to try is go to <your_local_maven_repo>\org\apache\maven\plugins\maven-war-plugin\2.1.1 and check for files called *.lastUpdated. If any exist, delete them and try again.

Actually, that message reads like you're attempting to UPLOAD a change to the master Maven repository, not download it like one normally would.

You'd have to be specifically authorized by the Maven people for that, and they'd only do that if you were a maven developer/committer, not an ordinary maven user.

The original message was:

Failure to transfer org.apache.maven.plugins:maven-war-plugin:pom:2.1.1 from http://repo1.maven.org/maven2

It is trying to take the plugin from http://repo1.maven.org/maven2 i.e. the central Maven repository.

I am pretty confident this is related to the lastUpdated files.

Thanks to Tim for promoting to an expert.

Thanks to James for that specific solution. It worked now.

Just a FYI - Instead of manually looking for and deleting those files, you can use the -U option of Maven:

mvn -U clean install

Where there is a will, there is a way.
Where there is a team, there is more than 1 way.

Thanks for your way, Jaikiran: Maven's way.
