`transformNativeLibsWithStripDebugSymbol` is not executing

Issue

I have a routine that expects AGP to produce app/build/intermediates/transforms/stripDebugSymbol/debug directory on assembleDebug. Also I have some aars with native code in my dependencies. It works pretty well on my local machine but doesn't work on my CI. I discovered that this folder is produced by task transformNativeLibsWithStripDebugSymbolForDebug. But on my CI it doesn't even have such task.

Task with path 'transformNativeLibsWithStripDebugSymbolForDebug' not found in project ':app'

Unfortunately I cannot tell what is wrong. At least not without AGP source code.

So the questing is: what triggers transformNativeLibsWithStripDebugSymbol to execute during assemble or how do I force it?

I'm using AGP 3.1.3 and gradle wrapper 4.5.

Solution

Eventually I found out that AGP will throw NDK-related tasks only if NDK is configured (duh), i.e. ndk.dir is set in local.properties or ANDROID_NDK_HOME/ANDROID_NDK (I'm not sure which one is mandatory) environmental variable is set.

UPD: According to AGP source code it is ANDROID_NDK_HOME, at least at the moment. https://android.googlesource.com/platform/tools/build/+/refs/heads/master/gradle/src/main/groovy/com/android/build/gradle/internal/Sdk.groovy#205
