It may be related to this change (?) - #355

...which bumped the maven-surefire-plugin dependency from 2.20.1 to 3.0.0-M3.

This is important to fix because it blocks our release process.

Steps to reproduce:

Run mvn clean test on the command line

Expected behavior:

Tests should execute and pass

Observed behavior:

Tests fail with ClassNotFoundException for JUnit4Provider.

Platform:

Master branch of library as of 8fd8cca

This seems to work fine on Travis with OpenJDK 11:

mvn install -DskipTests=true -Dmaven.javadoc.skip=true -B -V
mvn test -B

...but not on my machine - I get the same error.

This is now blocked by #399 using the most recent version of Maven.

[barbeau]

Using java version "11.0.12" 2021-07-20 LTS and apache-maven-3.8.4 on Windows 10 with:

mvn clean test

...I can no longer reproduce this (project builds successfully), so I'm closing this issue.
