Could not find or load main class org.apache.jmeter.NewDriver

[g1ps]

Hi,

Our builds are failing since updating to Gradle 6.0.1 with:

    > Task :xxxxxxxxxxx:jmRun FAILED
    Error: Could not find or load main class org.apache.jmeter.NewDriver
    Caused by: java.lang.ClassNotFoundException: org.apache.jmeter.NewDriver

    FAILURE: Build failed with an exception.

No amount of searching for plugin, Gradle, jMeter issues has helped. I've tried upgrading from 1.0.10-3.3 to 1.1.0-4.0. I've tried the dev version. Nothing works. there are no jMeter logs and build scans don't say anything more. Gradle upgrade guides don't mention anything that looks relevant. At present I'm stumped.

Thanks.
