• 关于com.android.tools.build:gradle:3.4.2的构建与apply plugin: 'com.novoda.bintray-release'之间的问题


    前言:

      当您在阅读这篇记录时,说明您也正在处理关于lib库上传到Bintray,并可能add to jcenter中去,那么就会遇到如下警告

    Android Studio Version:3.4.2

    Android Gradle Plugin Version:3.4.2

    Gradle Version:5.1.1

    Novoda Bintray:0.9

    根据以上IDE工具以及对应的插件版本,搭建了一个Android 项目,并配置好发布到Bintray,配置内容如下

    app的build.gradle:

    // Top-level build file where you can add configuration options common to all sub-projects/modules.

    buildscript {
    repositories {
    google()
    jcenter()

    }
    dependencies {
    classpath 'com.android.tools.build:gradle:3.4.2'
    classpath 'com.novoda:bintray-release:0.9'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
    }
    }

    allprojects {
    repositories {
    google()
    jcenter()

    }
    }

    task clean(type: Delete) {
    delete rootProject.buildDir
    }

    Module的build.gradle:

    apply plugin: 'com.android.library'
    apply plugin: 'com.novoda.bintray-release'
    
    android {
        compileSdkVersion 29
        buildToolsVersion "29.0.2"
    
    
        defaultConfig {
            minSdkVersion 19
            targetSdkVersion 29
            versionCode 1
            versionName "1.0"
    
            testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    
        }
    
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            }
        }
    
    }
    
    dependencies {
        implementation fileTree(dir: 'libs', include: ['*.jar'])
    
        implementation 'androidx.appcompat:appcompat:1.1.0'
        testImplementation 'junit:junit:4.12'
        androidTestImplementation 'androidx.test:runner:1.2.0'
        androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    }
    
    publish {
        userOrg = 'itsdf07'//bintray.com用户名
        groupId = 'com.itsdf07'//jcenter上的路径
        artifactId = 'lib-alog'//项目名称
        publishVersion = '1.0.0'//版本号
        desc = 'An ALog Util library'//描述,不重要
        website = 'https://github.com/itsdf07/UtilsALog'//网站,最好有,不重要
    }
    

      

    当搭建完项目之后进行构建,会发现AS报了如下警告:

    WARNING: API 'variantOutput.getPackageLibrary()' is obsolete and has been replaced with 'variant.getPackageLibraryProvider()'.
    It will be removed at the end of 2019.
    For more information, see https://d.android.com/r/tools/task-configuration-avoidance.
    To determine what is calling variantOutput.getPackageLibrary(), use -Pandroid.debug.obsoleteApi=true on the command line to display more information.
    Affected Modules: *****

    看到以上信息,我们都能看懂这个警告的原因是在当前的Android Gradle Plugin Version中,API->variantOutput.getPackageLibrary()已经过时了,替代它的是variant.getPackageLibraryProvider()

    那么我们会发现,搭建的项目,我们并没有使用到这些API接口,为什么会报出这个警告呢?

    经过跟踪与验证发现,这个是谷歌在做相应版本升级时遗留下来的问题,它并不是bug,只是会影响到同您一样,看到这个警告浑身不舒服的同类人!

    解决方案:

    1、等待升级,看是否能去掉这个警告

    2、降低版本,退回会出现这个警告之前的版本

    我的解决方案是:降低版本

    classpath 'com.android.tools.build:gradle:3.4.2'
