I expected the geronimo-javamail_1.4_spec package to be excluded from the build and, indeed, when I run mvn dependency:tree, it is no longer listed there.
However, when running the resulting jar, the JarClassLoader still complains about javax/mail classes being hidden by the geronimo ones...
Sure enough, when I examine the jar via 7-zip, I see that geronimo-javamail_1.4_spec-1.7.1.jar is still there (comes as part of the org.apache.cxf:cxf-api:jar:2.7.1:compile package).
How do I fully exclude a package? i.e. not only remove it from the dependency tree, but also not include it at all in the resulting jar?
Adding the onejar relevant xml per the comment below:
<plugin>
<groupId>com.jolira</groupId>
<artifactId>onejar-maven-plugin</artifactId>
<version>1.4.4</version>
<executions>
<execution>
<configuration>
<mainClass>com.corp.dept.proj.myclient</mainClass>
<onejarVersion>0.97</onejarVersion>
<attachToBuild>true</attachToBuild>
<!-- Optional, default is "onejar" -->
<classifier>onejar</classifier>
</configuration>
<goals>
<goal>one-jar</goal>
</goals>
</execution>
</executions>
</plugin>
Adding the output of the mvn dependency after the scope & debug options were specified per the answer below:

The onejar plugin adds all artifacts from maven's runtime scope, as it should be.
The command mvn dependency:tree does not seem to list all runtime dependencies properly though. Could be a bug, I don't know why.
Luckily, by adding a few parameters you can have all runtime scope dependencies listed.
mvn dependency:tree -Dscope=runtime -Ddebug=true
This will show that cxf-rt-core also has geronimo-javamail as dependency. So, your solution would be to explicitly add the core jar with an exclusion to your dependencies.
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-core</artifactId>
<version>2.7.1</version>
<exclusions>
<exclusion>
<groupId>org.apache.geronimo.specs</groupId>
<artifactId>geronimo-javamail_1.4_spec</artifactId>
</exclusion>
</exclusions>
</dependency>
