Cela fait plusieurs jours que je me casse la tête à ce sujet, mais je ne comprends pas pourquoi cela ne fonctionne pas.

Je l'ai compris. Rest-client-microservice est un projet Spring Boot et utilise le plugin suivant:

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <executions>
        <execution>
            <goals>
                <goal>repackage</goal>
            </goals>
        </execution>
    </executions>
</plugin>

Le fichier jar est reconditionné et tous les packages et les classes sont placés dans le dossier BOOT-INF. C'est la raison pour laquelle Maven est incapable de les trouver. Vous pouvez résoudre ce problème en définissant le plugin comme ceci:

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <executions>
        <execution>
            <goals>
                <goal>repackage</goal>
            </goals>
            <configuration>
                <classifier>exec</classifier>
            </configuration>
        </execution>
    </executions>
</plugin>

Avec cette configuration, le plug-in Spring Boot Maven créera 2 JAR: le principal sera identique à un projet Maven habituel, tandis que le second aura le classificateur ajouté et sera le JAR exécutable.

Pour Spring Boot 2, bootRepackage n'existe plus en tant que tâche. Il est remplacé par la tâche bootJar. Pour construire deux pots en utilisant Gradle, j'ai ajouté ceci à mon module de base:

jar {
    enabled = true
}
