Gradle run failed on multi module micronaut project

Question

I have a below project structure

Project product and API gateway share the common project as common. Since in the settings.gradle I have include the project as below

rootProject.name = 'src'
include 'common', 'fetebird-apigateway', 'fete-bird-product'

In the API gateway build.gradle I have include the below dependency

dependencies {
    implementation project(':common')
    }

In the product build.gradle I have include the below dependency\\

    plugins {
    id "com.github.johnrengelman.shadow" version "6.0.0"
    id "io.micronaut.application" version '1.0.3'
}

version "0.1"
group "fete.bird"

repositories {
    mavenCentral()
    jcenter()
}

micronaut {
    runtime "netty"
    testRuntime "junit5"
    processing {
        incremental true
        annotations "fete.bird.*"
    }
}

dependencies {
    annotationProcessor("io.micronaut.openapi:micronaut-openapi")
    annotationProcessor("io.micronaut.data:micronaut-data-processor")
    implementation("io.micronaut:micronaut-validation")
    implementation("io.micronaut:micronaut-runtime")
    implementation("javax.annotation:javax.annotation-api")
    implementation("io.micronaut:micronaut-http-client")
    implementation("io.swagger.core.v3:swagger-annotations")
    implementation("io.micronaut:micronaut-discovery-client")
    implementation("io.micronaut.rxjava3:micronaut-rxjava3")
    implementation("io.micronaut.kafka:micronaut-kafka")
    implementation("io.micronaut.data:micronaut-data-hibernate-jpa")
    implementation("io.micronaut.mongodb:micronaut-mongo-reactive")
    testImplementation("de.flapdoodle.embed:de.flapdoodle.embed.mongo:2.0.1")
    implementation project(':common')
    runtimeOnly("ch.qos.logback:logback-classic")
}

mainClassName = "fete.bird.ProductApplication"
java {
    sourceCompatibility = JavaVersion.toVersion('15')
    targetCompatibility = JavaVersion.toVersion('15')
}
tasks.withType(JavaCompile) {
    options.fork = true
    options.forkOptions.jvmArgs << '-Dmicronaut.openapi.views.spec=rapidoc.enabled=true,swagger-ui.enabled=true,swagger-ui.theme=flattop'
}

common.buid.gradle

plugins {
    id 'java'
}

group 'fete.bird'
version '1.0-SNAPSHOT'

repositories {
    mavenCentral()
}

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.12'
}

Product main class

public class ProductApplication {

    public static void main(String[] args) {
        Micronaut.run(ProductApplication.class, args);
    }
}

when I run the individual project with command line or intellj idea

$ gradle build

or

$ gradle run

Exception

The issue is with Project with path ':common' could not be found in root project 'fete-bird-product'.

Answer 1

I believe that your project structure is slightly incorrect. The root build.gradle should be in the root of the project, not in src .

I have created this repo some time ago, which leverages a multi-module setup. You can ignore the BuildSrc module if you want.
