Working with code E015
If you receive the output code E015, this means that an error occurred when Diffblue Cover tried to download the
junit-platform-launcher artifact. This prevents Diffblue Cover from validating the created tests.
If you have a Gradle project, add the JUnit launcher dependency appropriate for your JUnit version. (Please note that this step is not required for Maven projects.)
If you are still experiencing problems, please contact Diffblue Support.
