Harald Soevik commented on MEAR-64:
-----------------------------------

I've got one module that I want to explode: mt-jar.
{noformat}
          <modules>
            <ejbModule>
              <groupId>com.computas.mt</groupId>
              <artifactId>mt-jar</artifactId>
              <unpack>true</unpack>
            </ejbModule>
            <jarModule>
              <groupId>com.computas.mt</groupId>
              <artifactId>mt-xml-schema</artifactId>
            </jarModule>
            ...   
          </modules>
{noformat}

Then, mt-xml-schema has mt-jar as dependency:
{noformat}
  <dependencies>
    <dependency>
      <groupId>com.computas.mt</groupId>
      <artifactId>mt-jar</artifactId>
    </dependency>
    ...
  </dependencies>
{noformat}

Trying to build the EAR results in this output:
{noformat}
[INFO] [ear:ear]
...
[INFO] Copying artifact[ejb:com.computas.mt:mt-jar:1.0.8-SNAPSHOT] 
to[mt-jar-1.0.8-SNAPSHOT.jar] (unpacked)
[INFO] Expanding: 
/home/computas/.m2/repository/com/computas/mt/mt-jar/1.0.8-SNAPSHOT/mt-jar-1.0.8-SNAPSHOT.jar
 into 
/home/computas/matsys/mt-ear-clustered/target/mt-ear-clustered-1.0.8-SNAPSHOT/mt-jar-1.0.8-SNAPSHOT.jar
...
[INFO] Copying artifact[jar:com.computas.mt:mt-jar:1.0.8-SNAPSHOT] 
to[mt-jar-1.0.8-SNAPSHOT.jar]
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] Error copying EAR modules

Embedded error: 
/home/computas/matsys/mt-ear-clustered/target/mt-ear-clustered-1.0.8-SNAPSHOT/mt-jar-1.0.8-SNAPSHOT.jar
 (Is a directory)
{noformat}

Observe that the mt-jar artifact is being copied twice, producing an error 
because it already exists as an exploded artifact.

>            Priority: Minor
>
> I cannot find a way to explode an artifact when a project is directly 
> dependent on artifact B and transitively dependent on A. 
> Either A cannot be exploded because it is not defined as direct dependency, 
> or A cannot be included as transitive dependency because it has already been 
> exploded as a direct dependency. 
> Might be worth a fix ?
