NoClassDefFoundError on junit test execution

[Shashank Arora]

Hi,

I'm trying to run junit tests via taurus and getting "NoClassDefFoundError", See below exception details, and inline yaml file.  I found the following thread & bug with open jdk online but not sure if this is related. Any pointers will be helpful.

Hi,

First, please try to run your configuration without Taurus. If the error persists, it is not a Taurus error.

From the stack trace, I can see that this is a Blazemeter error, not a Taurus one. If it happens again, please contact their support.

BR,
Alla
