Easily read a property from gradle.properties and local.properties

GradleReadProperty.kts

// From my Codeberg page: https://codeberg.org/FlyingDutchman/GradleReadProperty/src/branch/main/getSetting

// Simply copy following code in your gradle.build.kts file
// Also use the following imports: java.io.File and import java.util.*
fun getSetting(key: String) = project.getSetting(key)
fun Project.getSetting(key: String): String {

    // Check if local properties
    val localProperty = rootProject.file("local.properties")
    if (localProperty.isFile) {
        val props = Properties().apply { load(localProperty.inputStream())}
        if (props.containsKey(key))
            return props[key].toString()
    }

    // Not in local, check gradle properties
    if (!project.properties.containsKey(key))
        throw Exception("Key $key not found in gradle.properties")
    return project.properties[key].toString()
}
