Android Studio 3.0:无法解析模块依赖性

Question

我有一个主要项目和第二个项目(模块).

在将模块项目作为模块依赖项导入到app项目并尝试同步所有内容后,我收到以下错误:

Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve project :module.
Could not resolve project :module.
Required by: project :app
Unable to find a matching configuration of project :module:

     - Found com.android.build.gradle.internal.dependency.VariantAttr 'release' but wasn't required.

     - Found com.android.build.gradle.internal.dependency.VariantAttr 'release' but wasn't required.
     - Required org.gradle.api.attributes.Usage 'java-api' and found incompatible value 'java-runtime'.

我在主app.gradle中的依赖:

compile project(':module')

我发现如果我将其更改为以下内容:

compile project(path: ':module', configuration:'default')

然后项目同步和构建.

但是在主项目类文件中,我无法从模块项目中导入任何文件.

花了几个小时寻找答案,到目前为止我发现的一切都没有帮助.直到重新安装Android Studio 3.0,但它没有帮助.

Answer 1

解决了我的问题.

我使用apply plugin创建了测试模块:'com.android.application'应该使用apply plugin:'com.android.library'.

虽然项目中可以有多个应用程序模块,但是不能让应用程序模块依赖于其他应用程序模块.
