Cannot build Camera2Basic

[stevebroshar]

Please follow the following instructions before filing a bug:

1. Github issues under this project are only for sample-related issues. If you have modified the sample code in any way, then this is probably not the appropriate place to report a bug.
2. If you are trying to report a bug related to the CameraX library then you can do so at the Android Issue Tracker: https://issuetracker.google.com/components/618491.
3. Include the specific sample where you found the issue, in addition to device model and specific Android build number -- which can be found under Settings > About phone.
4. Include error logs from logcat, if there are any.
5. If you can, also attach a bug report-- but please keep in mind that personal information can sometimes be found in those, so double check before attaching.

Summary: I cannot build Camera2Basic. I would hope and assume samples would be easy to build. But I get one error after another. And I find no instructions on how to get it building. Not a very useful sample if I can't build it.

Sample: Camera2Basic Target: Pixel 7 API 34 (also tried API 30) Using latest from https://github.com/android/camera-samples/tree/main/Camera2Basic Open in Android studio 2023.1.1 Fails to build with logged message: Unsupported Java. Your build is currently configured to use Java 17.0.7 and Gradle 6.7.1. Possible solution:

• Upgrade Gradle wrapper to 7.2 version and re-import the project Clicked link to upgrade gradle; seems to have succeeded Build still failing; there is no log output, but almost immediately, I see popup: Unable to find Gradle tasks to build: [:]. Build mode: ASSEMBLE. Tests: All. A few seconds later, clicked build again (no other changes) and then it started building!!! Fails with LOTS OF INFO (too much!). There is a hierarchy of errors logged and two popups! What is the important stuff?????

The longest log message is as follows:

Does compile after upgrading gradle plugin per suggestion in popup. So... it's not really a suggestion. It's a requirement.

Can't the sample be updated so consumers don't have to figure this out? Or at least put a LOUD note in the readme.
