android單個library module時，上傳aar到私有maven倉庫

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'// 版本號(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'  // 組名 (com/demo/MavenDemo/1.0.0.0/MavenDemo-1.0.0.0.aar)

def POM_PACKAGING = 'aar'// 包類型

def POM_DESCRIPTION = 'lib for android'// 描述

def NEXUS_USERNAME = 'admin' // 用戶名

def NEXUS_PASSWORD = 'admin123'// 密碼

def NEXUS_REPOSITORY_URL = 'http://localhost:8081/repository/maven-releases/' //倉庫地址

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.上傳aar

1.如圖點擊uploadArchives上傳

2.在studio控制檯，執行命令

gradlew uploadArchives

三.引用aar

1.聲明maven服務器

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.問題記錄

1.引用aar報401錯誤

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：沒有配置賬號密碼

解決辦法：

添加如下代碼

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

}

2.有多個library module串聯時，無法正確引用aar

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

原因： implementation project(':mylibrary2') 這樣引用lib工程，生成的pom文件有問題

<dependency>
      <groupId>MavenDemo</groupId>
      <artifactId>mylibrary2</artifactId>
      <version>unspecified</version>
      <scope>compile</scope>
 </dependency>
