Checking for updates of versioned dependencies

[Ext.Manish.Shah]

Hi,

I was hoping someone could help explain this observed behaviour (maven
2.0.4).

We have setup an internal repository (using Codehaus proxy repository).
We have a large number of dependencies in our maven build. However, for
a particular subset of these dependencies, maven performs an update
check once per day on both our internal repository (te-uk) and the maven
central repository. Here is the logging from maven -

[INFO] artifact org.eclipse.ant:org.eclipse.ant.core: checking for
updates from te-uk
[INFO] artifact org.eclipse.ant:org.eclipse.ant.core: checking for
updates from central 

Now, this only happens for this one particular set of jar dependencies.
An exmple of one of the culprits is -

<dependency>
  <groupId>org.eclipse.core</groupId>
  <artifactId>org.eclipse.core.resources</artifactId>
  <version>3.2.0</version>
</dependency>

There are 20 other dependencies that are all from the org.eclipse.core
group. These are fetched from the repository at
http://repo1.maven.org/eclipse. Every one of these gets the update check
once per day. However, they are declared exactly the same way as any of
our other versioned dependencies which never get an update check.

It is a problem because once per day our build takes 5 mins longer than
necessary. I explicitly do not want an update check on any of our
versioned dependencies (if I did, I would use snapshots). Hence, our
repository is configured as follows -

  <repositories>
    <repository>
      <id>te-uk</id>
      <name>TE-UK Repository</name>
      <url>http://us000099.pun.dom:9999/repository</url>
      <releases>
        <enabled>true</enabled>
        <updatePolicy>never</updatePolicy>
        <checksumPolicy>warn</checksumPolicy>
      </releases>
      <snapshots>
        <enabled>false</enabled>
      </snapshots>
    </repository>
  </repositories>
  <pluginRepositories>
    <pluginRepository>
      <id>te-uk</id>
      <name>TE-UK Repository</name>
      <url>http://us000099.pun.dom:9999/repository</url>
      <releases>
        <enabled>true</enabled>
        <updatePolicy>never</updatePolicy>
        <checksumPolicy>warn</checksumPolicy>
      </releases>
      <snapshots>
        <enabled>false</enabled>
      </snapshots>
    </pluginRepository>
  </pluginRepositories>

I've tried playing around with the updatePolicy on the repository, but
it has absolutely no effect whatsoever.

Any help to explain this behaviour would be appreciated.

Thanks,
Manish
