Class diagram generates duplicate class exporting to image

Question

Hello,

I send you a class diagram example which image generates a duplicate class "Source" in the package A instead of printing a arrow from class "Target" (package B) and existing class "Source" (package A).

If there is some error in my sample code, I would like to know it, please.

Thank you very much.

Best regards,

Alejandro.

package "A" {

    class Source {

        att : string

    }

}

 

package "B" {

    class Target {

        att : string

    }

 

    Target "0..*" --> "0..1" A.Source

}

Short answer:
You should use namespace instead of package:
 
@startuml
namespace A {
    class Source {
        att : string
    }
}
namespace B {
    class Target {
        att : string
    }
    Target "0..*" --> "0..1" A.Source
}

The explanation is here: http://plantuml.sourceforge.net/classes.html#Namespaces

This is due to the fact that "package" in PlantUML does not define a namespace (and this is very different of what's happen in java's packages).

Nevertheless, your example shows a bug in PlantUML, but it's because you mixed up package with namespace (using A.Source).
The situation is not easy to fix, so we are waiting for having a good way of solving thoses package/namespace issues.
