Maven 依赖关系显示在依赖关系树中，但没有导入 jar

Question

The project I am working at has many levels and a parent pom, so, hard to assess the ultimate result of dependencies imported.

However, looking into the dependency:tree and the effective pom, I can see i am correctly importing JUnit-jupiter 5.5.2, but i cannot see the jar on the list of maven dependencies on my project, I actually see JUnit-jupiter 5.2.0.

Already tried mvc clean install -U

Any ideas?

jars and dependecy:tree

effective-pom

Answer 1

The reason for JUnit-jupiter 5.2.0 is still in your project could be due to, it comes as a transitive dependency of some other dependency. What you can do is look for parent dependency of JUnit-jupiter 5.2.0 and exclude transitive dependencies from it.

Use graphical dependency tree of your project and expand all transitive dependencies and search jupiter library. If there is JUnit-jupiter 5.2.0 as a transitive dependency you can exclude it as below.

    <dependency>
        <groupId>it.some.parent</groupId>
        <artifactId>parent-library</artifactId>
        <version>${parent.library.version}</version>
        <scope>provided</scope>
        <exclusions>
            <exclusion>
                <groupId>*</groupId>
                <artifactId>*</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

Answer 2

Managed to import the correct jar by excluding the transitive dependency in dependency management in pom:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <version>${spring-boot.version}</version>
            <scope>test</scope>
            <exclusions>
                <exclusion>
                    <groupId>junit</groupId>
                    <artifactId>junit</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
