DESCRIBE THE ISSUE IN DETAIL:

With the following project structure:

A base app module
A plain Kotlin module called library with some classes defined that also uses kapt/dagger2
A dynamic feature module feature which depends on library, and makes use of code from library.

Launching an activity from the feature module causes a NoClassDefFoundError when trying to instantiate the class(es) defined in the library module.

This only seems to happen when Dagger2 is applied to the library module and when code is generated via kapt. If all dagger-related code is removed from the library module then the class loading works fine. When dagger2 is applied it is actually also possible to instantiate the classes that are generated by dagger, despite the manually-defined classes being absent from the dex path.

A project that reproduces this error is available here: https://github.com/dellisd/manifest-boom/tree/dagger-wtf (on that particular branch).

Another behaviour of this issue is that changing the app deploy method from "Default APK" to "APK from app bundle" fixes this issue in that project, however the same problem has been observed in other larger projects when using "APK from app bundle". It's been difficult to reproduce in a smaller project, but presumably it is related to the issue described here.

STEPS TO REPRODUCE:

Clone this branch from this project https://github.com/dellisd/manifest-boom/tree/dagger-wtf
Run the app
Observe the crash in logcat
Change the deploy method to "APK from app bundle" in the run configuration
Launch the app and observe no crash

Thanks for reporting, would you be able to provide a reproducible case for when this incremental error occurs? The task for merging java resources has multiple incremental inputs depending on where the java resource originates - providing a sample project where this issue can be triggered will help the team narrow what task input is impacted. A longer stacktrace of the issue from #1 might also be useful.

Unfortunately I cannot reproduce it consistently. In fact I don't even know what triggers it (it seems to be some combination of changes).

Like I mentioned above, my hunch is that this is due to having several modules with the same name (impl). The resource in question (impl_debug.kotlin_module) contains the name of the Gradle module and it likely means that there will be conflicts since there are several modules with the same name.

The stack trace looks like this:

Thanks for the additional information. I have refactored the Java Resource merging incremental handling to better handle source file path roots - so hopefully this is enough to eliminate the possibility of collisions between java resources. However, it would be great to test these changes resolve your issue. My current assumption is that the issue occurs when there is a library structure where there are two modules of the same name nested within two differently named modules such as:

app
foo_lib
  foo
bar_lib
  foo

Could you confirm that this setup is similar in your project or if not, can you please provide your project structure or even a project if possible?

de...@squareup.com <de...@squareup.com> #5Oct 4, 2022 09:06PM

Yes, our setup looks like this:

:features
  :feature1
    :public
    :impl
  :feature2
    :public
    :impl
...

The modules mentioned in the error would always be one of these impl or public modules.

Unfortunately I cannot share our project and even if I could, I don't know how to replicate the issue.

I will say though that since upgrading to the latest AGP 8.2 alpha I have not seen the issue so it's possible that it's already been fixed as a part of another change.

de...@squareup.com <de...@squareup.com> #6Oct 6, 2022 07:06PM

Oops, spoke too soon. It just happened.

Once it happens ever run will trigger it so if you need me to log or try something let me know. Removing the app level build directory fixes the issue.

BTW, what is the target release for this fix?

de...@squareup.com <de...@squareup.com> #8Oct 31, 2022 01:53PM

For now, we've worked around this by adding this to our Kotlin convention plugin:

tasks.withType<KotlinCompile>().configureEach {
    compilerOptions {
        moduleName.set(path.removePrefix(":").replace(":", "_"))
    }
}

bi...@google.com <bi...@google.com> Oct 31, 2022 11:16PM

Accepted by bi...@google.com.

ga...@google.com <ga...@google.com> #9Nov 7, 2022 11:26AM

Thanks for sharing the workaround. I needed to slightly adapt it to work for us, otherwise kapt and ksp would fail because they'd expect different names for internal symbols.

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompilationTask.class).configureEach {
    if (!name.containsIgnoreCase("ksp") && !name.containsIgnoreCase("kapt")) {
       compilerOptions {
       moduleName.set(path.substring(1).replace(":", "_"))
    }
}

bi...@google.com <bi...@google.com> #10Jan 10, 2023 01:38AM

Actually, I found a better way to solve this. The default module name is based on the base plugin's archivesName property. So you can do this instead:

base {
    archivesName.set(path.removePrefix(":").replace(":", "_"))
}

de...@squareup.com <de...@squareup.com> #11Jan 26, 2023 04:23PM

It seems AGP is not correctly excluding kotlin_module files during java resource merging, so we'd expect a collision - although this error message isn't clear.

Until we release we have a fix for the issue, a workaround may be to add packagingOptions { exclude 'META-INF/*.kotlin_module' } to the build.gradle conflicting libraries, so AGP doesn't attempt to merge them.

ga...@google.com <ga...@google.com> #12Jan 26, 2023 05:11PM

Alternatively you can give them unique names e.g.

kotlin {
    compilerOptions {
        moduleName.set(project.path)
    }
}

applied to all projects

bi...@google.com <bi...@google.com> #13Feb 9, 2023 07:21PM

Marked as fixed.

We set the module to the dashified project gradle path. Kinda feel like this should be the default for the module merging issue in general

hu...@google.com <hu...@google.com> #14Feb 10, 2023 12:40PM

In my case, I had similar errors with MergeJavaResourcesTask
But in my case, errors were against for META-INF metadata from Google AutoService instead of kotlin-module

And I did set same workaround with Comment #8, then errors were gone.
