android单个library module时，上传aar到私有maven仓库

一.gradle新建uploadArchives task

1.添加upload-aar.gradle的文件

apply plugin: 'maven'

def POM_NAME = 'pomName'// pomName

def POM_VERSION = '1.0.0.0'// 版本号(com/demo/MavenDemo/1.0.0.0/MavenDemo-1.0.0.0.aar)

def POM_ARTIFACTID = "MavenDemo"// aar包名(com/demo/MavenDemo/1.0.0.0/MavenDemo-1.0.0.0.aar)

def POM_GROUPID = 'com.demo'  // 组名 (com/demo/MavenDemo/1.0.0.0/MavenDemo-1.0.0.0.aar)

def POM_PACKAGING = 'aar'// 包类型

def POM_DESCRIPTION = 'lib for android'// 描述

def NEXUS_USERNAME = 'admin' // 用户名

def NEXUS_PASSWORD = 'admin123'// 密码

def NEXUS_REPOSITORY_URL = 'http://localhost:8081/repository/maven-releases/' //仓库地址

uploadArchives {
    repositories {
        mavenDeployer {
            repository(url: NEXUS_REPOSITORY_URL) {
                authentication(userName: NEXUS_USERNAME, password: NEXUS_PASSWORD)
            }
            pom.project {
                name POM_NAME
                version POM_VERSION
                artifactId POM_ARTIFACTID
                groupId POM_GROUPID
                packaging POM_PACKAGING
                description POM_DESCRIPTION
            }
        }
    }
}

2.build.gradle添加apply from

apply from: 'upload-aar.gradle'

二.上传aar

1.如图点击uploadArchives上传

2.在studio控制台，执行命令

gradlew uploadArchives

三.引用aar

1.声明maven服务器

maven {
    url "http://localhost:8081/repository/maven-releases/"
    credentials {
         username = "admin"
         password = "admin123"
     }
}

2.引用aar

 implementation 'com.demo:MavenDemo:1.0.0.0'

四.问题记录

1.引用aar报401错误

Could not resolve com.demo:MavenDemo:1.0.0.0

Could not GET 'http://localhost:8081/repository/maven-releases/com/demo/MavenDemo/1.0.0.1/MavenDemo-1.0.0.1.pom'. Received status code 401 from server: Unauthorized

原因：没有配置账号密码

解决办法：

添加如下代码

credentials {
         username = "admin"
         password = "admin123"

}

2.有多个library module串联时，无法正确引用aar

提示Error:Failed to resolve: MavenDemo:mylibrary2:unspecified

原因： implementation project(':mylibrary2') 这样引用lib工程，生成的pom文件有问题

      MavenDemo
      mylibrary2
      unspecified
      compile
