Maven的依赖版本冲突：应用程序使用Spring数据的Neo4j和Spring数据JPA

Question

下面是我的pom.xml的依赖关系，

<dependency> 
     <groupId>io.spring.platform</groupId> 
     <artifactId>platform-bom</artifactId> 
     <!--<version>1.1.4.RELEASE</version> --> 
     <version>2.0.7.RELEASE</version> 
     <type>pom</type> 
     <scope>import</scope> 
    </dependency> 
    <dependency> 
     <!-- Import dependency management from Spring Boot --> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-dependencies</artifactId> 
     <version>1.4.0.RELEASE</version> 
     <!--<version>1.2.7.RELEASE</version> --> 
     <type>pom</type> 
     <scope>import</scope> 
    </dependency> 

    <dependency> 
     <groupId>org.springframework.data</groupId> 
     <artifactId>spring-data-releasetrain</artifactId> 
     <version>Hopper-SR2</version> 
     <type>pom</type> 
     <scope>import</scope> 
    </dependency> 

    <dependency> 
     <groupId>org.springframework.data</groupId> 
     <artifactId>spring-data-neo4j</artifactId> 
     <version>4.1.0.RC1</version> 
    </dependency> 

    <dependency> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-data-jpa</artifactId> 
    </dependency> 

和许多其他依赖

我的应用程序使用内存用于交易数据存储的-derby（嵌入式配置文件）/ MySQL（远程配置文件）和用于处理分层数据存储的Neo4j图形数据库。我的要求是根据maven配置文件以远程和嵌入模式运行Neo4j。默认情况下，Spring版本管理器使用旧版本的Spring-data-neo4j（3.x.x），但嵌入式Neo4j支持仅在版本4.0.0后可用。当我建立我的如下图所示，上述我得到一个错误显示的配置应用，

我想这个错误是因为该版本冲突Spring的数据公地的。有没有办法解决这个错误？

Answer 1

Hopper-SR2支持Spring-data-neo4j 4.1.2。你为什么要降级到4.1.0.RC1？尝试删除降级或明确将其设置为4.1.2。

如果您仍然认为您获得了3.x版本，请运行下面的代码并查看3.x版本中的内容。

mvn dependency:tree -Dverbose -Dincludes=spring-data-neo4j 

您可以使用相同的过程来查找与spring-data-commons的冲突。只需更改include参数（或者为所有依赖项省略）。如果发现冲突，请在您的pom.xml中明确包含正确的版本。
