Build fail - Tests avec super classe dans un autre projet

Bonjour,

Je suis en train de me former (sur le tas) a maven, et il se trouve que j'ai un projet ayant cette structure :

- project 1
-- class Model
-- class TestModel

- project 2 depend de project 1
-- class Example extends Model
-- class TestExample extends TestModel

Comme vous pouvez le voir, je definis un modele et son test dans un projet, puis j'ai un autre projet qui definit une implementation particuliere de ce modele et les tests qui lui sont associes. Pour etre sur de le tester a fond, le test etend celui du modele (c'est fait pour evidemment, j'ai des fonctions a implementer pour pouvoir appliquer les tests du modele sur des instances des exemples). Sous Eclipse ca marche tres bien (run+test). Par contre sous Maven je n'arrive pas a avoir une compilation complete du projet 2.

Voila les poms adaptes (juste les noms de changes) :

Et quand sous Eclipse je lui demande de compiler, lancer les tests et tout par les fonctionnalites de base (sans passer par Maven), tout est bon. Ca compile, ca teste, ca lance. En revanche, quand, toujours sous Eclipse, je lui demande de me faire un Maven install, le projet 1 tout va bien, mais le projet 2 voila ce que ca me fait :

Notez que je n'ai pas d'erreur pour les classes non test (Model + Example ici), seules les classes de test m'embetent ici.

Bonjour,

Pour Maven, un projet Java va se diviser en 2 : d'une part le JAR qui contient le code source de l'application, d'autre part, le JAR contenant le code source des tests.

Pour résoudre ton problème, il faut faire 2 choses :

1. Demander à Maven de créer et déployer / installer le JAR de test de ton premier module. Cela se fait simplement dans le pom.xml comme ceci :
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <executions> <execution> <goals> <goal>test-jar</goal> </goals> </execution> </executions> </plugin>
Grâce à cela, Maven déploiera non seulement ta lib.jar, mais aussi lib-tests.jar.

2. Il faut déclarer dans ton second module, une dépendance au premier module (comme tu l'as fait), mais cette fois ci sur le JAR de test :
Code:

1 2 3 4 5 6 7 <dependency> <groupId>${project.parent.groupId}</groupId> <artifactId>project1</artifactId> <version>LATEST</version> <type>test-jar</type> <scope>test</scope> </dependency>
Là, ça devrait aller mieux !

Je rajoute la dépendance ou je la remplace ?

J'avais déjà rajouté ce style de dépendance (copier-coller de l'autre + changer le scope à test), et ça m'avait surchargé la première dépendance, du coup j'avais plus celle à la compilation des sources. Cela dit je n'avais pas de type spécifique.

Alors j'ai ajouté la génération + la dépendance. Effectivement il me génère le JAR de test et il ne me fait plus d'erreur de compilation... il me dit carrément qu'il est incapable de trouver la dépendance :

Pourtant si je regarde dans le dossier target du projet 1, j'ai bien les "project1-1.0.0.jar" + "project1-1.0.0-tests.jar" (j'ai bien rebuildé le projet 1 avant le 2, avec un clean avant). Si j'ai bien compris, il cherche les infos au mauvais endroit, c'est ça ?

Tu as du faire un "mvn package", c'est ça ?

Il faut faire un "mvn install". En gros, Maven va packager ton application (créer les .jar), puis les installer dans ton repository local. C'est là où Maven va toujours chercher les dépendances.

Génial ça marche, merci {^_^}b.
