Intermittent NoSuchMethodError during ComponentProcessingStep

[kevinguitar]

Hello 👋

We are getting a NoSuchMethodError intermittently in the KAPT task after updating to Dagger 2.56. Please let me know if you need any further information 🙏

Caused by: java.lang.NoSuchMethodError: 'com.google.common.collect.ImmutableSet com.google.common.graph.Graphs.reachableNodes(com.google.common.graph.Graph, java.lang.Object)'

Hmm, NoSuchMethodError typically means that the method existed in the version of Guava that was used to compile Dagger but does not exist during compilation of your library. However, this usually shouldn't happen because we list the required version of Guava (v33.3.1) in Dagger's pom file (shown below) and Gradle's default resolution strategy should ensure that you have that version (or higher) of the dependency:

https://repo1.maven.org/maven2/com/google/dagger/dagger-compiler/2.56/dagger-compiler-2.56.pom

It's also weird because this particular source file hasn't changed in a very long time (since Dagger 2.25 released in 2019)

https://github.com/google/dagger/blob/dagger-2.25/java/dagger/internal/codegen/extension/DaggerGraphs.java#L94

I guess the best place to start is:

1. Which version of Dagger are you upgrading from?
2. Which version of Guava is Gradle resolving (There's some Gradle command to list the dependencies it resolves)

[kevinguitar]

Yeah, it's very weird that it happened some some of our devs only, one of them could only reproduce it by hitting the run button in Android Studio, but it's fine by assembling the app from terminal.

Which version of Dagger are you upgrading from?

From 2.55

Which version of Guava is Gradle resolving

These are the dependencies I got from dagger compiler, it seems correct according to the bom file, but the thing is we cannot reproduce it by assembling the app from command line

Fails 100% for me with the same error when upgrading 2.55 -> 2.56.1.

The method was added in 33.1.0 (link) and I'm using Gradle 8.13 + kapt.

Kapt isolates in a Gradle worker process, I wonder if that somehow ends up using the wrong guava version, as the one bundled with Gradle (and on the worker classpath) is 32.1.2.

[madisp]

Looks like an issue in how kapt does classloader isolation when using worker processes, I reported it to JB:

• KT-76388 kapt worker process isolation uses wrong classes for processor

As a workaround these things in tandem worked for me:

• kapt.workers.isolation=none in the gradle.properties file
• the Gradle module that has kapt+dagger in it cannot use a separate JVM toolchain for compilation - this always forces a separate worker process for invoking kapt

[kevinguitar]

@madisp oh thanks, this is very useful!

[bcorso]

The method was added in 33.1.0 (link) and I'm using Gradle 8.13 + kapt.

Note that the method return type was changed to ImmutableSet in v33.1.0, but it's been available with return type Set since v20.0 (and Dagger only needs the latter).

Thus, we could try downgrading Guava on our side to < 33.1.0 if you think that would fix the issue.

Though, it sounds like this is a Gradle bug and the real fix should be on their side (e.g. maybe they need to shade their version of Guava to avoid conflicts), so if you have a workaround I'm leaning towards just leaving it as is.

[jokellyfenton]

I am also experiencing this issue but my package does not use Gradle. It looks like this is the same as @BenSlabbert above. When I check my Maven dependency tree I see that there are multiple different versions of Guava that are being resolved to v33.3.1. For example:

Is it a requirement that every dependency be compiled with Guava 33.3.1 for the maven component to compile successfully with dagger v2.56?

Is it a requirement that every dependency be compiled with Guava 33.3.1

I don't think it's currently a requirement, but we do need to be able to update Guava at some point.

OTOH, it looks like Dagger currently declares a dep on Guava 33.0.0, but some other dependency must be bumping the version to 33.3.1 via rules_jvm_external conflict resolution strategy.

While, I don't even see a good way (from rules_jvm_external's documentation) to determine why the version is being bumped, I think we can at least force the declared version (Guava 33.0.0) to take precedent using a the force_version = True conflict resolution strategy for this dependency for now.

I'll try to get a 2.56.2 patch with this fix sometime this week.
