Ivy project can't get the latest Maven snapshot (with assembly plugin)

Question

When a Ivy project depends a maven project (using assembly plugin), there will be problems. For example:

Maven project: Suppose the maven project will deploy 2 snapshot packages: for exmaple, one is my-app-1.0.0-20130504.000602-1.jar and the other is my-app-1.0.0-20130504.001348-1-myzip.zip. The pom.xml is shown below.

<modelVersion>4.0.0</modelVersion>
<groupId>com.mycompany.app</groupId>
<artifactId>my-app</artifactId>
<packaging>jar</packaging>
<version>1.0.0-SNAPSHOT</version>

<... ...>

<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-assembly-plugin</artifactId>
      <version>2.2.1</version>
      <configuration>
        <descriptors>
          <descriptor>src/main/assembly.xml</descriptor>
        </descriptors>
      </configuration>
      <executions>
        <execution>
          <id>make-assembly</id>
          <phase>package</phase>
          <goals>
            <goal>single</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-deploy-plugin</artifactId>
      <version>2.7</version>
      <configuration>
        <groupId>${project.groupId}</groupId>
        <artifactId>${project.artifactId}</artifactId>
        <version>${project.version}</version>
        <packaging>zip</packaging>
        <file>my-app-1.01-myzip.zip</file>
      </configuration>
    </plugin>
  </plugins>
</build>

</project>

The Ivy project

The Ivy project depends on the 2 artifacts published by above maven project. The ivy.xml is shown below:

<configurations>
  <conf name="get-maven" />
</configurations>      
<dependencies>
  <dependency org="com.mycompany.app" name="my-app" rev="1.0.0-SNAPSHOT" changing="true" conf="get-maven->default">
    <artifact  name="my-app" ext="jar" type="jar"></artifact> 
    <artifact  name="my-app" ext="zip" type="zip" m:classifier="myzip"></artifact>  
  </dependency>
</dependencies>

Issues: Each time when the maven project deploy new snapshot to the artifactory server, the ivy project can retrieve the latest my-app-xxx.jar from the artifacory server but it can't retrieve the latest my-app-xxx-myzip.zip (ivy can't get to know that the zip is updated and just retrieve the zip from local cache). What I have to do is to delete the local cache, and run the ivy project again.

I did some investigation, and found the ivy task "convertpom" didn't convert the app-xxx-myzip.zip from pom to ivy, and only 1 artifact (the my-app-xxx.jar) can be found in the converted ivy.xml. Not sure if this is the root cause.

Can anyone help on this? How can I get the lastet snapshots for both artifacts in ivy project?

So to clarify, you're attempting to configure ivy to pull down a snapshot dependency published by a Maven project?

In that case, the following answer will help to explain:

What's wrong with this Ivy changingPattern / SNAPSHOT configuration?
