HuskyLens Package - com.qualcomm.hardware.dfrobot

[pavuluris]

I just downloaded the latest version of the RobotController and when i try build the code, it is failing with the package com.qualcomm.hardware.dfrobot does not exist. It points to the sample file from External folder SensorHuskyLens.java

It also points to several other errors as below.

Is this a clean build, or did you “refresh” or “upgrade” an existing package in the same location? It sounds as if you need to clean your build, clear your cache, and build again (for whatever reason it’s not building the new changes).

Hi Danny, I upgraded the project and performed the clean and build again and it reported the same issue.

[ddiaz]

I’m sorry, did you say this was a perfectly clean 9.0.1 version with no changes, or is this your team’s project you’re updating? It seems like you didn’t integrate changes properly, and the new samples were integrated but the dependencies to the core SDK didn’t come over.

When I pull a completely fresh 9.0.1 with no changes, I don’t see this problem whatsoever.

What does your build.dependencies.gradle file look like?

-Danny

EDIT: Fixed filename, thanks @cmacfarlane

[cmacfarlane]

Along the lines of what ddiaz is saying, I suspect your build.dependencies.gradle file does not contain the v9.0.1 artifacts, which would imply your update process was not complete.

See: https://github.com/FIRST-Tech-Challenge/FtcRobotController/blob/master/build.dependencies.gradle

Thank you @ddiaz and @cmacfarlane for your help and resources. I pulled the project again and just updated my ‘teamcode’. all other issues resolved automatically. I think the problem was that the dependecies were NOT properly integrated in my code base.

Thank you for your timely help, greatly appreciated!
