    Upgrading to SDK 6.2 Causes Build Failure (package not found)

    This morning I tried to upgrade our project to 6.2. I did the upgrade as I usually do (using Android Studio):
    • Download the new code from GitHub (https://github.com/FIRST-Tech-Challe...obotController) to my local computer
    • Created a new Branch for the SDK update
    • Manually copied everything except the TeamCode directory from the download to my new branch (overwriting files/folders as necessary)
    At this point, I tried to build the project and I get errors indicated "package <xyz> does not exist" (see output below).

    I'm sure this is a process problem, but I've done it this way for the past few years. Can anyone point me in the right direction?

    As an interesting side note, when I switch back to the "master" branch, the problems persist. If I delete the folder from disk, then re-clone from github, I'm able to build again.

      Often Android Studio gets confused when you change branches with different gradle files. I suggest forcing a gradle sync.

        alan_16072 Thanks for the suggestion. I tried to force a Gradle sync, but I'm still getting the same issue. I've tried rebuilding the project, I've tried invalidating caches, but I'm still not able to get the project to build after updating to the new SDK.

          There were some gradle file changes in 6.2 that you're probably not picking up with your non-standard update process.

          Generally the two ways to do an update are:
          1) If using git, add the FIRST repo as an upstream remote and pull from it
          2) If not using git, download ZIP of new SDK and copy ONLY the src/main/java folder of the TeamCode module from the previous project into the new one.
