Am I the only one getting this?

Ah, sorry about this - this is a known issue in Studio with our setup in AndroidX. Instead of running / installing the demos from inside studio, you will need to install them from command line:

./gradlew ui:integration-tests:demos:installDebug

Will this apply to any other module(app) I’ll add to the project?

Yup, this is because we disable test coverage when running the gradle build from inside studio, and there is an issue with recent versions of AGP where this causes the exception you listed. Alternatively, you can locally just comment out this line in AndroidXPlugin.kt

buildTypes.getByName("debug").isTestCoverageEnabled =
          !project.hasProperty("android.injected.invoked.from.ide")

Although this may increase build times a bit, not sure

Getting this now 😛

When running from command line? Or inside studio?

command line

Yeah, I think you need to open a new terminal entirely

Just tried, did not solve the problem

😕 that's strange, maybe try nuking the out directory first?

worked 😄

Out of interest, is there anywhere you checked first for this error? I'm wondering where a good place to put this kind of 'known issues' information is - is the README in the compose directory discoverable / an obvious place to check? Maybe a hotlist?

I tried checking in more detail the build log, but no, since I’m in

repo

I knew google wouldn’t help
