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 }
}

As I stumbled upon this gist from search, I put my improved version here. I fixed some issues, such as:

• tokenize splits line not into two substrings but into as many as '=' chars it have. Needs to be replaced with split('=', 2)
• empty lines are not ignored. Added if for that

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

    def file = new File(path)
    if (file.exists()) {
        file.eachLine { line ->
            def pair = line.split("=", 2)
            if (pair.length == 2) {
                def (name, value) = pair
                env[name.trim()] = value.trim()
            }
        }
    }

    return env
}

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

It's still not perfect as any comments in .env file would break everything, but it's a bit better already

@mitasov-ra Cool, updated original to include your fix and basic comment filtering.
