Maven dependency version conflict: Application using Spring data Neo4j and Spring data JPA

Question

Here are the dependencies in my pom.xml,

    <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>

and many other dependencies

My application uses in-memory-derby (embedded profile)/MySQL(remote profile) for transactional data storage and Neo4j graph database to handle hierarchical data storage. My requirement is to run Neo4j in both remote and embedded mode based on the maven profile. By default spring version manager uses older version of Spring-data-neo4j (3.x.x) but the embedded Neo4j support is only available after release 4.0.0. When I build my application with the config shown above I am getting an error as shown below,

// ...exception stacktrace

I guess this error is because of the conflicting versions of Spring-data-commons. Is there a way to get around this error?

Hopper-SR2 has support for Spring-data-neo4j 4.1.2. Why are you downgrading to 4.1.0.RC1? Try removing to downgrade or explicitly setting it to 4.1.2.

If you still think you are getting a 3.x version, run the below and look for what is pulling in the 3.x version.

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

You can use the same process to look for conflicts with spring-data-commons. Just change the include parameter (or omit it for all dependencies). If you find a conflict, explicitly include the correct version in your pom.xml.
