Is there a way to suppress Opt-in requirement marker XXX is unresolved warnings? You apparently can't add opt-in args after dependency resolution because freeCompilerArgs is frozen so it makes convention plugins quite annoying because you have to either @OptIn everywhere in source, or deal with hundreds of useless build warnings if you opt in with your conventions plugins.

Not sure workaround is possible if you try to modify this argument based on the resolved dependencies

the comments indicate this is not possible anymore 😕

hmm this seems to work, but it really sucks since the dependency has to be explicit as this no longer relies on resolution, its just watching things get added to DependencyHandler

configurations.configureEach { c ->
      if (c.isCanBeResolved) {
        c.dependencies.whenObjectAdded {
          if (it is ExternalDependency) {
            if (it.group == "androidx.compose.animation") {
              tasks.withType(KotlinCompilationTask::class.java).configureEach { task ->
                // We only want to apply this compiler arg for modules that use compose
                with(task.compilerOptions.freeCompilerArgs) {
                  add("-opt-in=androidx.compose.animation.ExperimentalAnimationApi")
                  add("-opt-in=androidx.compose.animation.ExperimentalSharedTransitionApi")
                }
              }
            }
            if (it.group == "kotlinx.coroutines") {
              tasks.withType(KotlinCompilationTask::class.java).configureEach { task ->
                // We only want to apply this compiler arg for modules that use compose
                with(task.compilerOptions.freeCompilerArgs) {
                  add("-opt-in=kotlinx.coroutines.ExperimentalCoroutinesApi")
                  add("-opt-in=kotlinx.coroutines.FlowPreview")
                }
              }
            }
          }
        }
      }
    }

compiler team said that they are working on the solution via https://youtrack.jetbrains.com/issue/KT-78277

Hopefully that will also work for deprecation warnings, i'd like to try suppressing those globally but -Xsuppress-warning=DEPRECATION does nothing
