BOM

Sandwich publishes several artifacts that must move together. The Bill of Materials pins them all from one place, so only the BOM version has to be updated on a release.

dependencies {
    implementation(platform("com.github.skydoves:sandwich-bom:$version"))

    implementation("com.github.skydoves:sandwich")
    implementation("com.github.skydoves:sandwich-retrofit")
    testImplementation("com.github.skydoves:sandwich-test")
}

For Kotlin Multiplatform:

sourceSets {
    val commonMain by getting {
        dependencies {
            implementation(project.dependencies.platform("com.github.skydoves:sandwich-bom:$version"))

            implementation("com.github.skydoves:sandwich")
            implementation("com.github.skydoves:sandwich-ktor")
            implementation("com.github.skydoves:sandwich-ktor-serialization")
        }
    }
}

The BOM constrains every published artifact:

• sandwich
• sandwich-ktor
• sandwich-ktor-serialization
• sandwich-ktorfit
• sandwich-retrofit
• sandwich-retrofit-datasource
• sandwich-retrofit-serialization
• sandwich-test

A BOM only supplies versions. It does not add any dependency on its own, so each artifact still has to be declared.
