Wrong version of JUnit in dependencies - spring

Question

I want to run JUnit 5.4+ tests on my Spring Boot app so that I can use the #Order annotation on my tests. However, Maven resolves my POM to 5.3.2 regardless of what I try.
I've tried including all the dependencies I can think of manually, but then I end up with a mess of mismatched versions. I also tried clearing my entire ~/.m2/repository folder and rebuilding the tree, same results.
Relevant parts of mvn dependency:tree
[INFO] +- org.junit.jupiter:junit-jupiter-api:jar:5.5.0:test
[INFO] | +- org.apiguardian:apiguardian-api:jar:1.1.0:test

Where does the 5.3.2 come from?

Answer 1

Add this line to your the properties in your Maven pom.xml:
<junit-jupiter.version>5.5.0</junit-jupiter.version>
this will control the dependencies defined in dependency management within the spring boot poms (org.springframework.boot:spring-boot-dependencies).
The reason is: that org.springframework.boot:spring-boot-dependencies include junit-bom
<dependency>
<groupId>org.junit</groupId>
<artifactId>junit-bom</artifactId>
<version>${junit-jupiter.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
per default junit-jupiter.version is 5.3.2. So as long as you not change junit-jupiter.version, this bom will define that all not explicit listed dependencies (for example org.junit.jupiter:junit-jupiter-params) are of the version defined in org.junit:junit-bom:5.3.2
