gradle构建springboot项目瘦身,外部依赖jar的终极方法

1.为什么瘦身？

阿里云部署，每次改了代码，上传80多M到服务器，血与泪，如果把jar单独上传的话，那么影响就很小了，只需要传对应的jar上去就可以保证项目正常运行

2.方法build.gradle示例

buildscript {
    dependencies {
        //配置热部署
        classpath 'org.springframework:springloaded:1.2.8.RELEASE'
    }
}
//
plugins {
    id 'org.springframework.boot' version '2.0.5.RELEASE'
}

apply plugin: 'java'
apply plugin: 'io.spring.dependency-management'

dependencies {
    compile project(':cyjz-pojo')
    compile project(':cyjz-common')
    compile project(':cyjz-interface-auth')
    compile project(':cyjz-controller-fileUploadDownload')
    //如果要做jar包分离，此处必须要使用compile,不然系统启动失败，血的教训
    compile 'org.springframework.boot:spring-boot-starter-amqp'
    compile 'org.springframework.boot:spring-boot-starter-data-redis'
    compile 'org.springframework.boot:spring-boot-starter-jdbc'
    compile 'org.springframework.boot:spring-boot-starter-web'
    compile 'org.mybatis.spring.boot:mybatis-spring-boot-starter:1.3.2'
    testCompile 'org.springframework.boot:spring-boot-starter-test'
    compile 'com.alibaba.boot:dubbo-spring-boot-starter:0.2.0'
    compile 'org.springframework.session:spring-session-data-redis:2.0.6.RELEASE'
    compile 'mysql:mysql-connector-java:5.1.47'

}

//清除lib的jar
task clearJar(type: Delete) {
    delete "$buildDir/libs/lib"
}
//复制jar到lib里面去
task copyJar(type: Copy) {
    from configurations.runtime
    into "$buildDir/libs/lib"
}


bootJar {
    // 例外所有的jar
    excludes = ["*.jar"]
    // lib目录的清除和复制任务
    dependsOn clearJar
    dependsOn copyJar

   //  指定依赖包的路径
    manifest {
        attributes "Manifest-Version": 1.0,
                'Class-Path': configurations.runtime.files.collect { "lib/$it.name" }.join(' ')

    }
}

3.调用bootJar

4.直接java -jar xxx.jar即可运行项目
