Quale ambito di dipendenza per i driver JDBC Derby nell'interfaccia di integrazione (caienna)

Question

Sto cercando di compilare il mio pom.xml in modo da poter creare automaticamente lo schema del mio database quando si esegue 'mvn install'. Sto usando il "plugin di maven-cayenne" per fare questo. Questo è il plugin che viene chiamato (nella fase di test di integrazione), come posso vedere l'output. Ma il mojo fallisce con l'eccezione: (ho usato il flag -e e -X per vedere questo).

java.lang.ClassNotFoundException: org.apache.derby.jdbc.ClientDriver 

(ottengo lo stesso se provo e uso l'EmbeddedDriver e se non includo 'derbyclient' o semplicemente 'derby' come la mia dipendenza).

Ecco un pom.xml che dovrebbe replicare il problema. Sto usando MVN 3 su Windows. [Apache Maven 3.0.4 (r1232337; 2012-01-17 08: 44: 56 + 0000)]

Questo richiede anche un file "datamap.map.xml" cayenne valido (in src/main/risorse), ecco quello che ho fatto in precedenza:

<?xml version="1.0" encoding="utf-8"?> 
<data-map xmlns="http://cayenne.apache.org/schema/3.0/modelMap" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://cayenne.apache.org/schema/3.0/modelMap http://cayenne.apache.org/schema/3.0/modelMap.xsd" 
    project-version="6"> 
    <db-entity name="TEST"> 
     <db-attribute name="ID" type="INTEGER" isPrimaryKey="true" isMandatory="true"/> 
    </db-entity> 
</data-map> 

EDIT:

Aggiunta di ulteriori informazioni.

Il file derbyclient-10.10.1.1.jar contiene la classe 'org.apache.derby.jdbc.ClientDriver' (ha appena espanso il JAR da Netbeans).

La bandiera -X sembra dimostrare che il CLASSPATH sia correttamente riferimento alla JAR:

[DEBUG] (f) classpathElements = [<PROJECT-PATH>\mvn\target\classes, <HOME-DIR>\.m2\repository\org\apache\derby\derbyclient\10.10.1.1\derbyclient-10.10.1.1.jar]

Answer 1

Per assicurare che il driver Derby sia disponibile durante l'esecuzione del plugin (vs durante la compilazione del codice), è necessario aggiungerlo come dipendenza del plugin stesso:

<plugin> 
    <groupId>org.apache.cayenne.plugins</groupId> 
    <artifactId>maven-cayenne-plugin</artifactId> 
    <version>3.2M1</version> 
    <dependencies> 
     <dependency> 
     <groupId>org.apache.derby</groupId> 
     <artifactId>derbyclient</artifactId> 
     <version>10.10.1.1</version> 
     </dependency> 
    </dependencies> 
    .... 
</plugin>
