The build action for each one respectively are
⦁ EmbeddedJar
⦁ EmbeddedReferenceJar
⦁ EmbeddedReferenceJar
⦁ EmbeddedReferenceJar

After do this, we have to fix build issues into Metadata.xml file. At this momment, I've got the following metadata

<metadata>  
    <!-- fixup the namespaces, notice that we have to do onw for each namespace. -->
