# Abhängigkeiten in Pfadoperation-Dekoratoren { #dependencies-in-path-operation-decorators }

Manchmal benötigen Sie den Rückgabewert einer Abhängigkeit innerhalb Ihrer *Pfadoperation-Funktion* nicht wirklich.

Oder die Abhängigkeit gibt keinen Wert zurück.

Aber Sie müssen sie trotzdem ausführen/auflösen.

  <dependencies>
    <dependency>
      <groupId>test</groupId>
      <artifactId>a</artifactId>
      <version>0.2</version>
      <scope>system</scope>
      <systemPath>should-use-variables-and-not-hard-code-this-path</systemPath>
    </dependency>
    <dependency>
      <groupId>test</groupId>
      <artifactId>b</artifactId>
      <version>0.1</version>
      <scope>system</scope>

# Dependências em decoradores de operações de rota { #dependencies-in-path-operation-decorators }

Em alguns casos você não precisa necessariamente retornar o valor de uma dependência dentro de uma *função de operação de rota*.

Ou a dependência não retorna nenhum valor.

Mas você ainda precisa que ela seja executada/resolvida.

  <artifactId>child-artifact-id</artifactId>
  <version>11-SNAPSHOT</version>
  <name>Model inheritance test parent: module directory != artifactId</name>
  <description>
    artifactId == "child-artifact-id"
    but expect path on SCM and site == "child"
    feature: support "project.directory" property, ressembling future model addition of "directory" element along "artifactId"
