TestNGListener not found

Hello, I have added GroupDocs Conversion to my pom.xml as described on the website


But when running any test I get the following exception:

java.util.ServiceConfigurationError: org.testng.ITestNGListener: Provider not found

Can you please share a sample application using that issue could be reproduced? Also share your development environment details (e.g. OS and Java version).

Windows 10, Java version 1.8.0_181
It works with GroupDocs.Conversion for Java 17.7.1 but from 17.10 and higher I get this error


Please check/evaluate this open-source application. However, we’d recommend you to use latest API version that is 20.10.2. We’ve logged a ticket to upgrade Java Spring application to latest version. Please keep track of this GitHub issue link. Moreover, take a look at this console application that uses latest API version.
