java.lang.ClassNotFoundException zu Maven-Abhängigkeiten

Question

Wir haben eine Reihe von Spring-Boot-Anwendungen, die als Microservices organisiert sind und einige Monate erfolgreich ausgeführt werden. Wir haben Sprig Boot 1.3.3 verwendet.

Jetzt haben wir ein Problem mit Maven Build-Prozess zu Spring Boot 1.4.2 wechseln. Wir entwickeln Microservice-basierte Software-Architektur. Wir haben core.common Dienst, der von anderen Diensten verwiesen wird dependecies wie folgt aus:

<dependencies> 
    <dependency> 
     <groupId>com.group</groupId> 
     <artifactId>core.common</artifactId> 
     <version>0.0.1-SNAPSHOT</version> 
     <scope>compile</scope> 
    </dependency> 
</dependencies> 

Dieser Service ist verantwortlich für die gemeinsame Klassen und zu jeder anderen Diensten benötigt Methoden.

Wir verwenden auch separaten Service (root.service) alle anderen Dienste zu bauen und sie in jar Dateien zu verpacken. Dies ist der Teil von pom.xml von diesem root.service:

<parent> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-parent</artifactId> 
     <version>1.4.2.RELEASE</version> 
     <relativePath /> <!-- lookup parent from repository --> 
    </parent> 

    <modules> 
     <module>../core.adminservice</module> 
     <module>../core.locationservice</module> 
     <module>../core.reportservice</module> 
     <module>../core.userservice</module> 
     <module>../core.notificationservice</module> 
     <module>../core.trackingservice</module> 
     <module>../core.mappingservice</module> 
     <module>../core.common</module> 
    </modules> 

Bis geschaltet Frühling Boot-Version 1.4.2 konnten wir mvn clean install über root.service zu testen und bauen den Rest der tun Dienstleistungen von Module Spezifikation.

Nach Spring-Boot-Version 1.4.2 wechseln, wenn ich versuche, mvn clean install in root.service ich java.lang.ClassNotFoundException bin immer auszuführen. Ausnahmebedingungsnachricht besagt, dass keine der Dienste Module Spezifikation keine Klassen von core.common Service in bestimmten Service von Module finden kann. Wenn ich versuche, mvn compile oder mvn test laufen alles läuft gut und ich bekomme erfolgreiche Builds und Tests. Wenn ich versuche, Dienste von Eclipse zu betreiben, ist auch alles in Ordnung.

Haben Sie irgendwelche Ideen? Bitte helfen Sie.

Answer 1

Ich denke, dass aufgrund der Änderungen ist in strucutre der JAR-Datei von Spring-Boot 1.4 gemacht: Release Notes

Das Layout von ausführbaren Gläser hat sich geändert. Wenn Sie Spring Boot's Maven-, Gradle- oder Ant-Unterstützung verwenden, um Ihre Anwendung zu erstellen, hat diese Änderung keine Auswirkungen auf Sie.Wenn Sie selbst ein ausführbares Archiv erstellen, beachten Sie bitte, dass die Abhängigkeiten einer Anwendung nun in BOOT-INF/lib statt lib enthalten sind und die eigenen Klassen der Anwendung nun in BOOT-INF/classes verpackt sind und nicht im root von das Glas.
