Thank you for the report! We have a couple places that check some properties regarding that. Could you run the following command and let us know where the assertion fails? Thanks!

$ JAVA_OPTS="-ea" ./gradlew clean assembleRelease --no-daemon --stacktrace

Just for the record.

Ran that command, looks like the same stacktrace to me but I'l post it below. Let me know if you need any more info.

* Try:
Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Exception is:

Thank you for the trial. I expected to catch this assertion: https://r8.googlesource.com/r8/+/refs/heads/d8-1.5/src/main/java/com/android/tools/r8/ir/conversion/IRConverter.java#1162 but passing that means at least every method with deferred name computation is marked accordingly. Attached r8.jar has some logging that will reveal which method has such unreachable instruction at the end. Just in case, I attached the diff (against R8 1.5.30). Could you edit your top-level build.gradle as follows and see if the logging discovers something? If it's too verbose and contains something that you don't want to share publicly, you can send it to jsjeon@google.com Thanks!

buildscript {

    dependencies {
        classpath files($PATH_TO_R8_JAR)                 // Must be before the Gradle Plugin for Android.
        classpath 'com.android.tools.build:gradle:X.Y.Z' // Your current AGP version.
     }
}

* What went wrong:
Execution failed for task ':app:transformClassesAndResourcesWithR8ForSitAutomation'.
> java.lang.NullPointerException (no error message)

Thank you for your trial. I guessed we missed some places to copy the metadata/optimization info about certain methods, but it seems that methods with those instructions are correctly marked as expected. But, a bit surprised to see those remnants are quite pervasive.

This time, I'm chasing where those instructions are created and what methods we're visiting to remove them. Please use the attached r8.jar to collect logs? Thanks!

Btw, it seems like all those reflective uses come from libraries, e.g.,
* https://github.com/square/retrofit/blob/master/retrofit/src/main/java/retrofit2/Platform.java#L45
* https://github.com/urbanairship/android-library/blob/master/urbanairship-core/src/main/java/com/urbanairship/google/PlayServicesUtils.java#L136
* https://github.com/square/okhttp/blob/master/okhttp/src/main/java/okhttp3/internal/platform/AndroidPlatform.kt#L101

> Task :app:transformClassesAndResourcesWithR8ForSitAutomation FAILED

Don't see any other 'R8 logging' lines, sorry

No worries! Thank you so much for collecting logs so far. The lack of any other logging lines means, we are adding those kinds of instructions, but never revisit methods to remove them.

However, that's quite confusing because, we add those instructions if and only if obfuscation is enabled and we found reflection with constant strings; and also remove them if obfuscation is enabled. Missing the latter step while doing the former step seems quite contradictory. Could you tell me more about the configuration of task ':app:transformClassesAndResourcesWithR8ForSitAutomation'? E.g. do you have `-dontobfuscate` in your proguard rules? I guess minifyEnabled is set to be true?

Okay, I spot one possibility. Could you add `-printconfiguration full-configuration.txt` to your proguard configuration and share the generated `full-configuration.txt` with us?

Reproduced locally, but it'd really appreciated if you can confirm that somewhere in your proguard configuration there is `-addconfigurationdebugging`. Note that this could come from the library, and that's why I asked to use `-printconfiguration` to nail down. (If a library adds that rule and spreads it, we should contact them and ask them to remove that.) If you intentionally added it to debug configurations, I guess removing it would be a workaround.

So yes we do have -addconfigurationdebugging defined, and removing it causes it to build successfully, thanks for the help!

Thank you for the confirmation. That is a newly added, half-baked feature, and thank you for triggering this bug! :) I'm working on the fix, and make it ready to AGP 3.5 final.

Also, lowering the priority as there is a workaround.

This is fixed on master (https://r8-review.googlesource.com/c/r8/+/38601) as well as 1.5. You can use it by editing your top-level `build.gradle` as follows:

buildscript {

    repositories {
        maven {
            url 'http://storage.googleapis.com/r8-releases/raw'
        }
    }

    dependencies {
        classpath 'com.android.tools:r8:1.5.36'          // Must be before the Gradle Plugin for Android.
        classpath 'com.android.tools.build:gradle:X.Y.Z' // Your current AGP version.
     }
}

Hi,

We also have the same error using Android Studio 3.5.3 with gradle plugin 3.5.3. Can confirm that there is no line in proguard '-addconfigurationdebugging'.

> Can confirm that there is no line in proguard '-addconfigurationdebugging'

Note that, even though your proguard configuration doesn't have that directive, it could be the case that some other configurations can come from libraries' configurations. So, if `-printconfiguration` indeed doesn't have that directive, yeah that feature is not triggered. (https://www.guardsquare.com/en/products/proguard/manual/usage#printconfiguration)

However, it's been (believed to be) fixed for a long time, so this might be a different issue. I've filed a separate one: b/148021799
