Hi @Chaitanya-970, thanks for your interest in helping with this.
We don’t auto-assign issues based on a “please assign me” request alone.
Please first take a look at our contribution guidelines. Then briefly explain how you’d like to approach the issue. Once that’s clear, and an implementation has been agreed upon, a maintainer can assign it to you.

Hey, I checked out contributing.md sorry for not doing it before
I think i found the problem the Gradle plugin depends on the preprocessor module, which depends on app/utils.
If you look at the other modules like core or preprocessor, they all have a mavenPublishing { } block in their build.gradle.kts that configures them to publish to Maven Central.
But app/utils/build.gradle.kts is missing that block entirely. it has the mavenPublish plugin applied but no actual publishing configuration. So when the plugin tries to pull org.processing:utils:4.5.6 from Maven Central it's just not there.
I'd like to try fixing this.
The change would be just adding the mavenPublishing config to app/utils/build.gradle.kts, matching what the other modules already do (license info, developer info, scm).
Happy to put up a PR if this sounds like the right approach.

@catilac How does @Chaitanya-970's plan sound?
Chaitanya-970 commentedon Sep 8, 2026
@catilac @SableRaf
I've already implemented the solution
Should i raise a PR or is there a need to change anything from my approach?

@catilac @SableRaf
I've submitted the PR here: #1572.
I tested it locally with
./gradlew :app:utils:testandpublishToMavenLocaland the artifacts are generating as expected.Thanks.
