Expected and Results

See open-telemetry/opentelemetry-java-instrumentation#14388 It seems like when dependency is added with xxx(project(":foo")) it resolves to shadowjar output not the output of the regular jar task, so xxx(project(":foo")) behaves like xxx(project(":foo", configuration = "shadow")).
We bisected the shadow plugin and found that removing

fixes the issue. With that line removed the build will still fail because mergeServiceFiles() appears to work only with duplicatesStrategy = DuplicatesStrategy.INCLUDE. Not sure whether that is intentional or a bug.

Related environment and versions

shadow plugin 9.0.1
gradle 8.14.3

Reproduction steps

clone the branch used in open-telemetry/opentelemetry-java-instrumentation#14388 and run ./gradlew assemble or ./gradlew build -PskipTests=true

Anything else?
