gradle+springboot实现多项目分环境打包

父项目的build.gradle

// 统一配置版本号
buildscript {
    ext {
        springBootVersion='2.3.11.RELEASE'
        springCloudVersion='Hoxton.SR8'

    }
    // 脚本自身的插件仓库
    repositories {
        mavenLocal()
        maven{ url 'https://maven.aliyun.com/nexus/content/groups/public/'}
        mavenCentral()
    }
    dependencies {

// 全局配置
allprojects{

    targetCompatibility = 1.8

    tasks.withType(JavaCompile){
        options.encoding='UTF-8'

    }
    //gradle构建过程中的默认任务processResources，重写
    processResources {
        filesMatching('bootstrap.yml') {
            expand(project.properties)
        }
    }
    dependencyManagement {
        dependencies {

    }
}
wrapper {
    gradleVersion = '7.0.2'
    archivePath = 'wrapper/dists'
    distributionPath = 'wrapper/dists'
    distributionUrl = 'https://services.gradle.org/distributions/gradle-7.0.2-bin.zip'
}

上面的文件中，控制环境变量的代码块是

子项目的build.gradle

dependencies {
    implementation fileTree(dir:'libs',includes: ['*.jar'])
    implementation 'org.springframework.cloud:spring-cloud-dependencies'
    implementation 'com.alibaba.cloud:spring-cloud-alibaba-dependencies'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.springframework.boot:spring-boot-starter-parent'
    implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
    implementation 'com.alibaba.cloud:spring-cloud-starter-alibaba-nacos-discovery'
    implementation 'com.alibaba.cloud:spring-cloud-starter-alibaba-nacos-config'
    implementation 'org.springframework.cloud:spring-cloud-starter-openfeign'
    implementation 'com.alibaba:druid-spring-boot-starter'
    implementation 'mysql:mysql-connector-java'
    implementation 'com.github.pagehelper:pagehelper'
    implementation 'com.github.pagehelper:pagehelper-spring-boot-autoconfigure'
    implementation 'com.github.pagehelper:pagehelper-spring-boot-starter'
    implementation 'cn.hutool:hutool-all'
    implementation 'org.springframework.kafka:spring-kafka'

}

环境变量在bootstrap.ym中

#配置环境
spring:
  profiles:
    active: ${profile}

打包命令

gradle build -x test -Pprofile=dev

执行结果截图

-x test 是排除单元测试
-Pprofile=dev是传递环境参数
打包完成后，bootstrap.yml中的变量会替换为dev

打包时，外部依赖的jar，不打进jar包里
