Travis CI build failing with JUnit 5

I'm currently working on a Java project using Maven, GitHub, CodeCov and Travis and I have a problem with my tests. I'm using JUnit 5 for the tests and here's the pom.xml fragment of the dependencies:

<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-api</artifactId>
    <version>5.4.2</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-engine</artifactId>
    <version>5.4.2</version>
    <scope>test</scope>
</dependency>

I don't create any tests yet, I only have a empty test class with a method that does nothing but has the @Test tag. Here's the class:

package test.java.test;

import org.junit.jupiter.api.Test;

public class MainTests {

    @Test
    public void sampleTest() {
        // TODO
    }
}

And here's my travis.yml file on my project:

language: java
after_success:
  - bash <(curl -s https://codecov.io/bash)
script: 
  - "mvn test"

Running "mvn test" in my local machine doesn't provide any errors but my Travis build is failing because of this:

[ERROR] COMPILATION ERROR : 
[INFO] -------------------------------------------------------------
[ERROR] /home/travis/build/M1RZ4/TFG/src/test/java/test/MainTests.java:[3,29] package org.junit.jupiter.api does not exist
[ERROR] /home/travis/build/M1RZ4/TFG/src/test/java/test/MainTests.java:[7,10] cannot find symbol
  symbol:   class Test
  location: class test.java.test.MainTests

I'm not used to work with Travis so I don't know what I'm doing wrong.

EDIT: Added full pom.xml file
