This is a follow-up to my question about Play Services Cast Framework, where the solution seems to be updating from v17.0.0 to v18.0.0. The new version unfortunately has a dependency on Dagger 2, whilst the (large & complex) project is Dagger 1.
We are currently using:
api "com.google.android.gms:play-services-cast:17.0.0"
api "com.google.android.gms:play-services-cast-framework:17.0.0"
Updating these to 18.0.0 results in:

Ideally I'd be able to let the new version of the library use Dagger 2 whilst the rest of the app uses Dagger 1. Reworking the project to use Dagger 2 is a multi-week undertaking.
Any ideas?
What I've tried already:
Excluding Dagger 2 from the cast framework via:
api("com.google.android.gms:play-services-cast:18.0.0") {
exclude group:'com.google.dagger', module:'dagger'
}
api("com.google.android.gms:play-services-cast-framework:18.0.0") {
exclude group:'com.google.dagger', module:'dagger'
}
unsurprisingly resulted in:
java.lang.NoClassDefFoundError: Failed resolution of: Ldagger/internal/Preconditions;
at com.google.android.datatransport.runtime.DaggerTransportRuntimeComponent$Builder.setApplicationContext(com.google.android.datatransport:transport-runtime@@2.1.0:150)
Forcing the cast framework to use an older version via the following also resulted in duplicate classes:
configurations.all {
resolutionStrategy {
preferProjectModules()
dependencySubstitution {
substitute(module("com.google.dagger:dagger:2.22")).with(module("com.squareup.dagger:dagger:1.2.2"))
}
}
}
Potentially related questions that didn't help:
- Dagger 2 application using library that uses dagger 1 - No answers / comments.
- Dagger 1 and Dagger 2 package names conflict - Seems to be a different issue further down the line.
- How do I make Dagger 1 and Dagger 2 coexist together in one Android project? To do with migration, not resolving dependency in third party library.
