Exception in thread "main" java.lang.NoClassDefFoundError: pabeles/concurrency/ConcurrencyOps

[sc3sc3]

Hi,

I'm using boofcv via maven with

  <dependency>
    <groupId>org.boofcv</groupId>
    <artifactId>boofcv-all</artifactId>
    <version>1.1.6</version>
</dependency>

and get the following error:

Thanks
