Eu criei minha própria definição de destino. Funcionou perfeitamente até agora. Hoje abri essa definição de meta e recebi o seguinte erro para todos os sites de software que tenho lá:

<code>Unable to locate installable unit <unit name>
</code>

O arquivo de definição de destino é assim:

<code><?xml version="1.0" encoding="UTF-8" standalone="no"?>
