[Khurram Malik]

Hi everybody, i have a micronaut application with kotlin and gradle kotlin dsl. I want to pass env variables, such as DB_PASS=“XXX” DB_NAME=“XXX”, such that i can access them in main function. What is the best way to do it? My initial thought was to use gradle properties (-P) but i can’t seem to get them working. Any expert who knows what to do here?

plugins {
    id("org.jetbrains.kotlin.jvm") version "1.8.20"
    id("org.jetbrains.kotlin.plugin.allopen") version "1.8.20"
    id("com.google.devtools.ksp") version "1.8.20-1.0.10"
    id("com.github.johnrengelman.shadow") version "8.1.1"
    id("io.micronaut.application") version "4.0.0-M2"
}

version = project.properties["version"] as String? ?: "0.0.1"
group = "dk.****"

val kotlinVersion = project.properties["kotlinVersion"]
repositories {
    mavenCentral()
}

dependencies {
    implementation("io.micronaut:micronaut-jackson-databind")
    implementation("io.micronaut.kotlin:micronaut-kotlin-runtime")
    implementation("io.micronaut:micronaut-management")
    implementation("org.jetbrains.kotlin:kotlin-reflect:${kotlinVersion}")
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8:${kotlinVersion}")
    runtimeOnly("ch.qos.logback:logback-classic")
    runtimeOnly("com.fasterxml.jackson.module:jackson-module-kotlin")
    testImplementation("io.micronaut:micronaut-http-client")
}

application {
    mainClass.set("dk.***.ApplicationKt")
}
java {
    sourceCompatibility = JavaVersion.toVersion("17")
}

tasks {
    compileKotlin {
        compilerOptions {
            jvmTarget.set(org.jetbrains.kotlin.gradle.dsl.JvmTarget.JVM_17)
        }
    }
    compileTestKotlin {
        compilerOptions {
            jvmTarget.set(org.jetbrains.kotlin.gradle.dsl.JvmTarget.JVM_17)
        }
    }
}
graalvmNative.toolchainDetection.set(false)
micronaut {
    runtime("netty")
    testRuntime("kotest5")
    processing {
        incremental(true)
        annotations("dk.***.*")
    }
}
