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WARNING: API 'variantOutput.getPackageLibrary()' is obsolete and has been replaced with 'variant.getPackageLibraryProvider()'.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'
--->
classpath 'com.android.tools.build:gradle:3.2.1'
