我正在尝试重建我用kotlin编写的项目，但该项目始终因错误而失败
Program type already present: androidx.annotation.AnimRes
我尝试过
无效的缓存
清洁和重建
使用./gradlew build --stacktrace --info命令
但没有成功。
例外是

经过艰苦奋斗并在各处寻求帮助后，我发现./gradlew app:dependencies命令正在提供重要的输出来解决错误。
首先，错误是Program type already present: androidx.annotation.AnimRes
Program type already present表示存在命名冲突，在本例中为androidx.annotation库，该库由多个库使用。也就是说，其他库包含androidx.annotation library作为传递依赖项。要查看此库，我从项目的根文件夹（我的操作系统是Ubuntu）打开了终端，然后运行./gradlew app:dependencies命令。它产生了一长串的配置及其依赖性。下面是摘录。
debugCompileClasspath - Resolved configuration for compilation for variant: debug
+--- androidx.databinding:databinding-common:3.3.0-alpha07
+--- androidx.databinding:databinding-runtime:3.3.0-alpha07
| +--- androidx.lifecycle:lifecycle-runtime:2.0.0-alpha1 -> 2.0.0-rc01
| | +--- androidx.lifecycle:lifecycle-common:2.0.0-rc01
| | | \--- androidx.annotation:annotation:1.0.0-rc01 -> 1.0.0-rc02
| | +--- androidx.arch.core:core-common:2.0.0-rc01
| | | \--- androidx.annotation:annotation:1.0.0-rc01 -> 1.0.0-rc02
| | \--- androidx.annotation:annotation:1.0.0-rc01 -> 1.0.0-rc02
| +--- androidx.collection:collection:1.0.0-alpha1 -> 1.0.0-rc02
| | \--- androidx.annotation:annotation:1.0.0-rc02
| \--- androidx.databinding:databinding-common:3.3.0-alpha07
+--- androidx.databinding:databinding-adapters:3.3.0-alpha07
| +--- androidx.databinding:databinding-common:3.3.0-alpha07
| \--- androidx.databinding:databinding-runtime:3.3.0-alpha07 (*)
上面的摘录显示了debugCompileClasspath配置的一些依赖关系。我们可以看到androidx.databinding:databinding-runtime:3.3.0-alpha07包含androidx.annotation:annotation:1.0.0-rc02作为传递依赖关系。
它还包含androidx.lifecycle:lifecycle-runtime:2.0.0-alpha1，而后者又包含androidx.annotation:annotation:1.0.0-rc01。
androidx.annotation:annotation:1.0.0-rc01 -> 1.0.0-rc02表示将使用版本1.0.0-rc02代替版本1.0.0-rc01。
下面是./gradlew app:dependencies产生的相同长输出的另一个摘录
kapt
+--- androidx.lifecycle:lifecycle-compiler:2.0.0-alpha1
| +--- androidx.lifecycle:lifecycle-common:2.0.0-alpha1
| | \--- androidx.annotation:annotation:1.0.0-alpha1
| +--- org.jetbrains.kotlin:kotlin-stdlib:1.2.41
| | \--- org.jetbrains:annotations:13.0
| +--- com.google.auto:auto-common:0.6
| | \--- com.google.guava:guava:18.0 -> 23.3-jre
| | +--- com.google.code.findbugs:jsr305:1.3.9
| | +--- com.google.errorprone:error_prone_annotations:2.0.18
| | +--- com.google.j2objc:j2objc-annotations:1.1
| | \--- org.codehaus.mojo:animal-sniffer-annotations:1.14
| \--- com.squareup:javapoet:1.8.0
从上面我们可以看到androidx.lifecycle:lifecycle-compiler:2.0.0-alpha1包含1.0.0-alpha1的{{1}}版本
这意味着最后，我的模块androidx.annotation:annotation将具有两个版本app和1.0.0-alpha1，这会使构建失败。
为解决此错误，我通过在应用程序的build.gradle中添加以下代码块来删除传递依赖项
1.0.0-rc02所以我的应用程序的build.gradle看起来像这样
configurations {
compile.exclude group: 'androidx.annotation', module: 'annotation'
}
在那之后，我刚刚同步，清理并重建了我的项目。
答案 1 :(得分：7)
就我而言，我只是清理项目并重新构建它即可。
答案 2 :(得分：6)
要解决此问题，我在Android Studio终端中写了命令./gradlew clean，然后加油！
答案 3 :(得分：1)
我在CI环境中遇到此错误，因为我使用的是来自码头工人的jdk8-openj9 jdk。
切换到openjdk-8码头工人镜像解决了该问题。
答案 4 :(得分：1)
我遇到了同样的错误，可以通过在Gradle中添加这些行来解决。
repositories {
google()
jcenter()
repositories {
maven {
url "http://storage.googleapis.com/r8-releases/raw/master"
}
}
}
dependencies {
classpath 'com.android.tools:r8:1.6.84' // Must be before the Gradle Plugin for Android.
classpath 'com.android.tools.build:gradle:3.6.3'
}

在应用gradle文件中添加multiDexEnabled true。
