public class FooTest extends AbstractMojoTestCase {
           


        

Answer 1

Leaving this here for anyone who runs into this problem in the future:

smoke's answer does work, but make sure the versions of the dependencies included in yegor256's in the original question match. Adding org.apache.maven:maven-compat did not work for me until I had changed those 4 dependencies to also have version 3.0.5.

Answer 2

Recently I faced the same exception. After a bit researching I found that maven-compat plugin solves the problem:

<dependency>
    <groupId>org.apache.maven</groupId>
    <artifactId>maven-compat</artifactId>
    <version>3.0.5</version>
    <scope>test</scope>
</dependency>

Answer 3

Currently, the class org.apache.maven.repository.RepositorySystem is found in the lib maven-resolver-api. If after adding maven-compat, anybody here still gets the error, make sure to add maven-resolver-api artifact as dependency as well.

<dependency>
  <groupId>org.apache.maven.resolver</groupId>
  <artifactId>maven-resolver-api</artifactId>
  <version>1.3.1</version>
</dependency>
