How do you setup variables in build.gradle.kts-CodePudding

In build.gradle I Know you can do this

ext {
    dbUsername = System.getenv("DB_USER").toString()
    dbPassword = System.getenv("DB_PASS").toString()
    libsUserNameNew = System.getenv("LIBS_USERNAME_NEW").toString()
    libsPassNew = System.getenv("LIBS_PASS_NEW").toString()
    gitShortTag = System.getenv("SHORT_SHA").toString()
    repoName = System.getenv("REPO_NAME").toString()
    group = "app.test.customerservicepoc"
    mainClass = "app.test.customerservicepoc.CustomerServicePOC"
}

How can I achieve the same using build.gradle.kts This is what I have tried

var dbUsername =""
var dbPassword =""
var LibsUserNameNew = ""
var LibsPassNew = ""
var gitShortTag  = ""
var repoName = ""

and then

ext {
    dbUsername = System.getenv("DB_USER").toString()
    dbPassword = System.getenv("DB_PASS").toString()
    kyoskLibsUserNameNew = System.getenv("LIBS_USERNAME_NEW").toString()
    LibsPassNew = System.getenv("LIBS_PASS_NEW").toString()
    gitShortTag = System.getenv("SHORT_SHA").toString()
    repoName = System.getenv("REPO_NAME").toString()
    group = "app.test.mms"
}

during build I end up getting errors

What went wrong: 945 Cannot invoke "String.toString()" because the return value of "org.gradle.internal.classpath.Instrumented.getenv(String, String)" is null

I am migrating the project to kotlin gradle, how can I define the variables in kotlin gradle?

CodePudding user response：

Well, the issue is shown in

It compiled no problem. (And I'd assume it would work if the environment variables were set).

BUILD SUCCESSFUL in 25s

Update 2 a real test

I've actually done this

lateinit var something1: String
var something2: String? = null

ext {
    something1 = System.getenv("SHELL") ?: ""
    something2 = System.getenv("SHELL") ?: ""
}

tasks.register("printSomething") {
    println("Something 1 is $something1")
    println("Something 2 is $something2")
}

Then I ran ./gradle printSomething

And here's the result:
