Maven spring-data-mongodb showing lower version of mongodb-driver-core - spring

Question

I have a project that uses spring-data-mongodb. I define the following dependency on my pom.xml:
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-mongodb</artifactId>
</dependency>
The version is managed by the parent project and the version I define is 3.3.7.
However when I run mvn dependency:tree on the project I get the following entry:
\- org.springframework.data:spring-data-mongodb:jar:3.3.7:compile
[INFO] +- org.springframework:spring-tx:jar:5.1.10.RELEASE:compile
[INFO] +- org.springframework:spring-context:jar:5.1.10.RELEASE:compile
[INFO] | \- org.springframework:spring-aop:jar:5.1.10.RELEASE:compile
[INFO] +- org.springframework:spring-beans:jar:5.1.10.RELEASE:compile
[INFO] +- org.springframework:spring-expression:jar:5.1.10.RELEASE:compile
[INFO] +- org.springframework.data:spring-data-commons:jar:2.1.11.RELEASE:compile
[INFO] +- org.mongodb:mongodb-driver-core:jar:3.8.2:compile
[INFO] | \- org.mongodb:bson:jar:3.8.2:compile
The problem here is that the version of mongodb-driver-core (one line before the end of the output above) is much lower than the one defined in the specific version of spring-data-mongodb.
I cannot understand why this is happening... I need to use the lates version of mongodb-driver-core but for some reason I am getting a lower version. My projects pom.xml is listed below (only thing missing is a custom dependency which I don't want to disclose)

Any help would be appreciated.

Answer 1

Turns out that the spring-boot version defined in my parent pom.xml is the one that affects the spring-data-mongodb version. By raising the spring-boot version I solved the problem... thank you M. Deinum for the comment.
