Android build fails with “CompileExceptionError: 'arm64-android' could not be built. Log: '<failed reading log>'”

Hello,

On Thursday I successfully built an Android extension for Appodeal SDK version 3.4.2.0 using Defold.
Later, I tried to update the SDK to the latest version 3.10.0.0, but the Android build started failing with the following error:

ERROR: unspecified:-1: 'com.dynamo.bob.CompileExceptionError: 'arm64-android' could not be built.
Log: '<failed reading log>'

After that, even if I revert back to version 3.4.2.0, the same error still appears.
I also tried building the same project on another computer, but the result is identical — the Android build always fails with the same message.

For reference, I tested the build on two different macOS systems:

  • MacBook M1 (Apple Silicon)

  • iMac with Intel processor

Could you please help me understand what’s causing this issue or how to completely reset the Android build environment so I can build again?

First, I’d check the log.txt in the project build folder, what does the log say?

That’s the problem — the log.txt file is not created at all when this error happens. The console log looks fine, it takes a long time to build, but at the end there’s this error—and nothing else

The console log:

AppoDealExt.zip (64.7 KB) I created a test extension project without any extra files, and the error still occurs there as well. Could you check if the same error happens on your machines?
