多模块micronaut项目的分级运行失败

Question

我有一个下面的项目结构

​

​

项目产品和API网关共享公共项目。因为在settings.gradle中，我将项目包括在下面

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

在API网关build.gradle中，我包含以下依赖项

dependencies {
    implementation project(':common')
    }

在产品build.gradle中，我包含了下面的依赖项\

    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'
}

产品主级

public class ProductApplication {

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

当我使用命令行或智能概念运行单个项目时

$ gradle build

或

$ gradle run

异常

FAILURE: Build completed with 2 failures.

1: Task failed with an exception.
-----------
* Where:
Build file '/Users/macbook/Projects/FeteBird-Microservice/src/fete-bird-product/build.gradle' line: 37

* What went wrong:
A problem occurred evaluating root project 'fete-bird-product'.
> Project with path ':common' could not be found in root project 'fete-bird-product'.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

2: Task failed with an exception.
-----------
* What went wrong:
A problem occurred configuring root project 'fete-bird-product'.
> Failed to notify project evaluation listener.
   > Cannot query the value of extension 'application' property 'mainClass' because it has no value available.

问题在于Project with path ':common' could not be found in root project 'fete-bird-product'.

我相信你的项目结构有点不正确。根build.gradle应该位于项目的根中，而不是在src中。

不久前，我已经创建了这个存储库，它利用了多模块设置。如果需要，可以忽略BuildSrc模块。
