前言:
當您在閱讀這篇記錄時,說明您也正在處理關於lib庫上傳到Bintray,並可能add to jcenter中去,那么就會遇到如下警告
Android Studio Version:3.4.2
Android Gradle Plugin Version:3.4.2
Gradle Version:5.1.1
Novoda Bintray:0.9
根據以上IDE工具以及對應的插件版本,搭建了一個Android 項目,並配置好發布到Bintray,配置內容如下
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用戶名 groupId = 'com.itsdf07'//jcenter上的路徑 artifactId = 'lib-alog'//項目名稱 publishVersion = '1.0.0'//版本號 desc = 'An ALog Util library'//描述,不重要 website = 'https://github.com/itsdf07/UtilsALog'//網站,最好有,不重要 }
當搭建完項目之后進行構建,會發現AS報了如下警告:

WARNING: API 'variantOutput.getPackageLibrary()' is obsolete and has been replaced with 'variant.getPackageLibraryProvider()'.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,我們都能看懂這個警告的原因是在當前的Android Gradle Plugin Version中,API->variantOutput.getPackageLibrary()已經過時了,替代它的是variant.getPackageLibraryProvider()
那么我們會發現,搭建的項目,我們並沒有使用到這些API接口,為什么會報出這個警告呢?
經過跟蹤與驗證發現,這個是谷歌在做相應版本升級時遺留下來的問題,它並不是bug,只是會影響到同您一樣,看到這個警告渾身不舒服的同類人!
解決方案:
1、等待升級,看是否能去掉這個警告
2、降低版本,退回會出現這個警告之前的版本
我的解決方案是:降低版本
classpath 'com.android.tools.build:gradle:3.4.2'
--->
classpath 'com.android.tools.build:gradle:3.2.1'
