        ktlint()
    }
    java {
        target("**/*.java")
        googleJavaFormat()
            .reflowLongStrings()

            .reorderImports(false)
    }
    yaml {

}

tasks.named<ShadowJar>("shadowJar") {
    archiveBaseName.set("connector-shadow")
    archiveVersion.set("1.0")
    archiveClassifier.set("")
    manifest {

}

./gradlew shadowJar

list your project’s dependencies in tree view

see how to configuration

you need moidfy your build.gradle.kts

configurations {
    compileClasspath
}

./gradlew dependencies --configuration compileClasspath
