如何在Android中的主项目中包含库项目中使用的aar文件 [英] How to include aar files used in library projects in main project in Android
问题描述
如果我在app-> lib中保留重复的aar文件并在app-> gradle文件中定义它们的依赖关系，那么就没有问题了。但它不应该是正确的做法。
请在下面找到错误：
配置出现问题project'：app'。
无法解析配置'：app：_qaDebugCompile'的所有依赖关系。找不到：api-release :.在以下位置搜索：
https://jcenter.bintray.com//api-release//api-release-.pom
https://jcenter.bintray.com//api-release //api-release-.aar
file：/ D：/sample/sample-android-app/app/libs/api-release-.aar
file：/ D：/ sample / sample- android-app / app / libs / api-release.aar
必须为：
sample-android-app：app：unspecified> sample-android-app：misnapworkflow：unspecified
请在下面找到项目结构：
sample
| - app
| - misnapworkflow
|
| - lib
| - api-release.aar
应用程序gradle文件已被提及包含该项目
依赖关系{compile project（'：misnapworkflow'） }
请在下面找到misnapworkflow gradle文件：

aar 文件不包含传递依赖项，并且没有描述所使用的依赖项的pom文件这意味着如果你使用 flatDir repo 导入aar文件，必须在您的项目中指定依赖关系。
您应该使用 maven存储库私有或公共Maven回购），你不会有同样的问题。
在这种情况下，gradle使用包含依赖关系列表的pom文件下载依赖关系。
My project is including some library project. Library is using some aar files and its dependecny is already defined in the module: gradle file. I am facing problem in including this library in my project.
If I keep duplicate aar files in app->lib and define their dependency in app->gradle file then there is no problem. But it shouldn't be the right approach.
Please find below the error:
A problem occurred configuring project ':app'.
Could not resolve all dependencies for configuration ':app:_qaDebugCompile'. Could not find :api-release:. Searched in the following locations:

In app gradle file following has been mentioned to include the project
dependencies { compile project(':misnapworkflow') }
Please find below the misnapworkflow gradle file:

}
tasks.whenTaskAdded { task ->

task.dependsOn grantPermissions
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:appcompat-v7:23.0.1'
// Add dependency for MiSnap external API
compile(name: 'api-release', ext: 'aar')
// Add dependency for MiSnap
compile(name: 'misnap-release', ext: 'aar') {
exclude module: 'appcompat-v7'
}
// Eventbus dependency
compile 'de.greenrobot:eventbus:2.4.0'
// Add OPTIONAL dependency for Manatee
compile(name: 'manatee-release', ext: 'aar')
compile(name: 'cardio-release', ext: 'aar')
}
repositories {
flatDir {
dirs 'libs'
}
}
The aar file doesn't contain the transitive dependencies and doesn't have a pom file which describes the dependencies used by the library.
It means that, if you are importing a aar file using a flatDir repo you have to specify the dependencies also in your project.
You should use a maven repository (you have to publish the library in a private or public maven repo), you will not have the same issue.
In this case, gradle downloads the dependencies using the pom file which will contains the dependencies list.
