Description

The copy goal seems to ignore the -U command line option. With the configuration below and -U set, the most recent snapshot of an artifact is not fetched if there is a reasonably new (in my case a few hours) snapshot version cached in the local repository. This is not sufficient. Afaik -U is supposed to force the check for new snapshot versions.

When I delete the local snapshot artifact, the MOJO logs the message

[INFO] snapshot example-group:example-artifact:0.1.0-SNAPSHOT: checking for updates from example-nexus

However no such line is printed out when there is an outdated local snapshot artifact and -U is set.

Example configuration:

<build>
  <plugins>
    <plugin>
      <artifactId>maven-dependency-plugin</artifactId>
      <version>2.1</version>
      <executions>
        <execution>
          <id>copy-snapshot</id>
          <phase>compile</phase>
          <goals>
            <goal>copy</goal>
          </goals>
          <configuration>
            <artifactItems>
              <artifactItem>
                <groupId>example-group</groupId>
                <artifactId>example-artifact</artifactId>
                <version>0.1.0-SNAPSHOT</version>
                <overWrite>true</overWrite>
              </artifactItem>
            </artifactItems>
            <stripVersion>true</stripVersion>
          </configuration>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>

Btw. copy-dependencies seems to honour the -U option, but copy-dependencies may not be appropriate for all people's use cases.
