Maven: artefact manquant org.springframework: spring: jar: 4.2.6

Question

J'ai un projet Web dynamique dans SpringToolSuite. Il est converti en un projet Maven. 

Je reçois le problème: 

Mising artefact org.springframework: spring.jar: 4.2.6

J'ai déjà essayé de nettoyer, de reconstruire et d'exécuter le projet. Il donne: 

Erreur de lecture du fichier C:\Utilisateurs\jublikon.m2\référentiel\org\springframework\printemps\4.2.6\spring-4.2.6.jar C:\Utilisateurs\jublikon.m2\repository\org\springframework\spring\4.2.6\spring-4.2.6.jar (Le système ne peut pas trouver le fichier spécifié)

Je ne comprends pas pourquoi il demande des fichiers jar alors que j'utilise Maven?

J'ai déjà vu ce post mais de toute façon je ne suis pas capable de résoudre mon problème. 

 

Quand j'exécute 

mVN propre installer

dans le répertoire racine du projet, je reçois: 

>mvn clean install

J'ai également vérifié mes paramètres de proxy. Le fournisseur actif dans Eclipse est défini sur 'natif' et je ne suis pas connecté via un proxy

Dans l'annuaire 

~/.m2/settings.xml

main is org.Apache.maven.cli.MavenCli from plexus.core

set maven.home default ${user.home}/m2

[plexus.core]
optionally ${maven.home}/lib/ext/*.jar
load       ${maven.home}/lib/*.jar
load       ${maven.home}/conf/logging

Answer 1

Je suis à peu près sûr qu'il n'y a pas d'artefact appelé "printemps"

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring</artifactId>           <!-- *** spring doesn't *** exist  -->
    <version>4.2.6</version>
</dependency>

En fonction des composants Spring dont vous avez besoin, vous devez inclure ces dépendances:

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>4.2.6.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>4.2.6.RELEASE</version>
    </dependency>

Dans mon projet Spring, j'inclus les artefacts Spring via une nomenclature:

<properties>
    <spring.version>4.2.6.RELEASE</spring.version>
</properties>

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-framework-bom</artifactId>
            <version>${spring.version}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

<dependencies>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-aspects</artifactId>
    </dependency>
<!-- more -->
</dependencies>

Answer 2

Ce qui a bien fonctionné pour moi, c’est que j’ai téléchargé les fichiers jar de mvnrepository. Je les ai ajoutés à partir du chemin de construction, puis j’ai fait une nouvelle installation compile dans Maven build, puis validé le projet puis mis à jour le projet. 

Answer 3

Maven télécharge par défaut les dépendances requises dans votre référentiel local afin qu'elles puissent être consultées plus rapidement. Peut-être que la dépendance est soit corrompue, soit supprimée de votre disque local? Avez-vous vérifié que C:\Users\jublikon.m2\repository\org\springframework\spring\4.2.6\spring-4.2.6.jar existe réellement et qu'il s'agit d'un fichier jar de printemps valide?
