Updating from 9.2.0 to 9.6.1 broke service file merging in composite build

[Privatech38]

Expected and Results

Project A depending on project B should not attempt to merge service files of project B.

Related environment and versions

Gradle version 9.6.1, plugin version 9.6.1, Windows.

Reproduction steps

Step 1:
Create a composite build/project where the project being included has dependencies requiring merging of service files like Flyway:

dependencies {
    implementation("org.flywaydb:flyway-core:13.1.0")
    implementation("org.flywaydb:flyway-mysql:13.1.0")
}

and set the strategy as:

    shadowJar {
        duplicatesStrategy = DuplicatesStrategy.EXCLUDE
        mergeServiceFiles()
        filesMatching("META-INF/services/**") {
            duplicatesStrategy = DuplicatesStrategy.INCLUDE
        }
    }

Step 2:
Build the first project which shades the included project, therefore both projects run the shadowJar task.

Step 3:
Analyze both archives. Included project's archive has correctly merged service files when the main project's service files are replaced by one of the two.

Anything else?

Setting the same strategy on main project fixes this.

Any reproducer?

Can't reproduce in #2145.

Can't reproduce in #2145.

Any difference if you set the java plugin to java-library?

[Goooler]

Nothing has changed. Both java and java-library are working.

The problem was my build script where I removed the shadowJar task actually running on the included project.
I apologise.
