maven Embedded error: No such archiver

Question

I am completely new to maven.

I am trying to do a coverage analysis of the test in robocode. For that I am using clover (trial license) since emma doesn't seem to able to handle multi-module projects very well.

Unfortunately, when it gets to the robocode.test.robots module i get the error:

[ERROR] BUILD ERROR
[INFO] Unknown archiver type

Embedded error: No such archiver: 'api/target/classes'.

I have tried Googling the problem but I haven't found examples using the same tag as the one in the pom file I have.

Here is the pom file (I only added the clover plugin part):

            <artifactId>maven-clover2-plugin</artifactId>
        </plugin>

    </plugins>
</build>
</project>

As far as I understand it the problem lies in the unpack-dependencies part.

Hi danny: I've had problems with unpack-dependencies myself and bet that's the "unknown archiver" type comes out of that direction. Do you give the robocode.version on the command-line? Are the dependencies jars oder zips? Perhaps a change of the output directory could help, too. — Jan, Mar 26 '12 at 09:01

By looking carefully the stacktrace you'll see which line(dependency) is causing the build failure.

As you can see, the last line is where the build failed. So, in this case, some problems with a bouncycastle dependency. To solve the issue i excluded it from the module i was told to use:

         <dependency>
            <groupId>com.worldchecker</groupId>
            <artifactId>mod.basic</artifactId>
            <version>4.0.0-RELEASE</version>
            <exclusions>
                <exclusion>
                    <groupId>org.bouncycastle</groupId>
                    <artifactId>*</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

And then the build succeed.

Looks to me like you hit the following bug: http://jira.codehaus.org/browse/MDEP-194. A solution seems to be to upgrade the dependency-unpack plugin and specify mvn install (instead of mvn test)
