Sounds like I just need to update the mockito version: mockito/mockito#1243 (comment)

[JeffFaer]

Also, it looks like the mockito team has their own version of this extension (mockito/mockito#1221). Expect me to delete this version in the near future.

[JeffFaer]

I just pushed https://github.com/JeffreyFalgout/junit5-extensions/releases/tag/junit5-extensions-1.0.1 to Maven central. Let me know if that doesn't work for you.

Thats working thanks.
