Load `.env` into gradle run

build.gradle

def static getenv(path = ".env") {
    def env = [:]

    def file = new File(path)
    if (file.exists()) {
        file.eachLine { line ->
            line = line.trim()
            if (line != "" && !line.startsWith("#")) {
                def pair = line.split("=", 2)
                env[pair[0].trim()] = pair.length == 2 ? pair[1].trim() : ""
            }
        }
    }

    return env
}

run {
    getenv().each { name, value -> environment name, value }
}
