Why tests are executed with junit-jupiter (aggregator) but not using separate dependencies?

I'm using Maven to build a Spring boot project.

When I set Junit jupiter dependencies like this 

<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-api</artifactId>
    <version>5.5.1</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-engine</artifactId>
    <version>5.5.1</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-params</artifactId>
    <version>5.5.1</version>
    <scope>test</scope>
</dependency>

I got the error

juil. 23, 2019 10:47:42 PM org.junit.platform.launcher.core.DefaultLauncher handleThrowable AVERTISSEMENT: TestEngine with ID 'junit-jupiter' failed to discover tests java.lang.NoClassDefFoundError: org/junit/platform/engine/support/discovery/SelectorResolver

But when I set dependencies using aggregator, tests are executed normally.

<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter</artifactId>
    <version>5.5.1</version>
    <scope>test</scope>
</dependency>

So what's are the difference between this two ?

You are missing junit-platform-launcher artifact. See official JUnit 5 User Guide:

JUnit 5 = JUnit Platform + JUnit Jupiter + JUnit Vintage

You should add this to your pom.xml:

<dependency>
    <groupId>org.junit.platform</groupId>
    <artifactId>junit-platform-launcher</artifactId>
    <version>1.5.2</version>
    <scope>test</scope>
</dependency>
