我最近将我的项目更新为从Android Studio 3.3进行构建,其中涉及进行以下更改(在Android Studio启动时提示)
build.gradle依赖项:
classpath 'com.android.tools.build:gradle:3.3.0'
渐变包装:
distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.1-all.zip
当尝试使用Google Maps进行同步时,这在功能模块中产生了许多错误。我使用的是play-services-maps版本16.0.0:
implementation "com.google.android.gms:play-services-maps:16.0.0"
尝试同步gradle时出现的错误是:
ERROR: Unable to resolve dependency for ':featureModule@flavorDebugFeature/compileClasspath': Could not resolve androidx.annotation:annotation:1.0.0.
ERROR: Unable to resolve dependency for ':featureModule@flavorDebugFeature/compileClasspath': Could not resolve androidx.annotation:annotation:1.0.1.
ERROR: Unable to resolve dependency for ':featureModule@flavorDebugFeature/compileClasspath': Could not resolve androidx.core:core:1.0.0.
ERROR: Unable to resolve dependency for ':featureModule@flavorDebugFeature/compileClasspath': Could not resolve androidx.core:core:1.0.1.
此模块中所有可能的风味变体组合都会重复此操作。
值得指出的是,该项目几个月前已迁移到androidX,并且运行良好。
错误的解决方法是将以下内容添加到该失败模块的gradle依赖项中:
implementation "androidx.annotation:annotation:1.0.1"
implementation "androidx.core:core:1.0.1"
然后,该应用可以正常编译并在设备上运行。完善。在我们尝试在项目上发布之前在CI构建中运行lint之前,我们遇到了麻烦,出现了错误消息:

如果我们删除2个新的依赖项(加上Google Maps,这似乎是对核心库和注释库的要求的原因),则此问题将消失。
我已经在此处和通过Google进行了一些搜索,其他人也看到了Expected task 'processFlavorDebugAndroidTestJavaRes' output files to contain exactly one file, however, it contains no files.
异常,他们的解决方案是确保基本的build.gradle文件具有baseFeature true
标志在defaultConfig
中,它已经存在于我的项目中。
在解决这个问题方面,我现在无所适从。
