Hilt, androidTest build failed in versions >= 2.40.4

Last working version is 2.40.3. Every test class generates next error:

> Task :app:hiltJavaCompileDevDebugAndroidTest
app/build/generated/hilt/component_sources/devDebugAndroidTest/.../..._TestComponentDataSupplier.java:8: error: cannot find symbol
import dagger.hilt.android.internal.testing.root.DaggerDefault_HiltComponents_SingletonC;
                                                ^
  symbol:   class DaggerDefault_HiltComponents_SingletonC
  location: package dagger.hilt.android.internal.testing.root

With final error:

error: dagger.internal.codegen.ComponentProcessor was unable to process 'dagger.hilt.android.internal.testing.root.Default_HiltComponents.SingletonC' because not all of its dependencies could be resolved. Check for compilation errors or a circular dependency with generated code.

I don’t see any errors which may hint why Default_HiltComponents.SingletonC is not generated.

Any more information I can provide?

After updating to the 2.42 version the initial problem happens again.

@mik9 thanks for the error report!

I don’t see any errors which may hint why Default_HiltComponents.SingletonC is not generated.

That error message indicates that Default_HiltComponents.SingletonC is already generated but it cannot be processed because one of its dependencies cannot be found on the classpath. I’m currently working on improving the error message to include more information about which exact type could not be found.

I should hopefully have something by next week that you can try out using the HEAD-SNAPSHOT artifacts. The better error message should allow you to pinpoint what’s going wrong. I’ll update this thread once that’s ready.
