我是一个有篮球的新手,我有一个依赖性问题。我有以下项目结构:
-MyApp
-MyAppLibrary
-MyAppPro
-MyAppFree
-ThirdPartyLibraryWrapper
--libs\ThirdPartyLibrary.aar
MyAppPro
和MyAppFree
都取决于MyAppLibrary
,这取决于ThirdPartyLibraryWrapper
。顾名思义,ThirdPartyLibraryWrapper
是外部库的包装器,即ThirdPartyLibrary.aar
。
这是我的配置:
build.gradle MyAppPro
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
applicationId "com.example"
minSdkVersion 8
targetSdkVersion 22
}
buildTypes {
release {
minifyEnabled true
proguardFiles 'proguard.cfg'
}
}
}
dependencies {
compile project(':MyAppLibrary')
}
build.gradle MyAppLibrary
apply plugin: 'com.android.library'
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
minSdkVersion 8
targetSdkVersion 22
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_7
targetCompatibility JavaVersion.VERSION_1_7
}
}
buildTypes {
release {
minifyEnabled true
proguardFiles 'proguard.cfg'
}
}
}
dependencies {
compile project(':ThirdPartyLibraryWrapper')
compile 'com.squareup.picasso:picasso:2.5.2'
}
build.gradle ThirdPartyLibraryWrapper
apply plugin: 'com.android.library'
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
minSdkVersion 8
targetSdkVersion 22
}
buildTypes {
release {
minifyEnabled true
proguardFiles 'proguard.cfg'
}
}
}
repositories {
flatDir {
dirs 'libs'
}
}
dependencies {
compile(name: 'ThirdPartyLibrary-0.1.0', ext: 'aar')
compile "com.android.support:support-v4:22.0.0"
compile fileTree(dir: 'libs', include: 'volley.jar')
compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.3'
}
当gradle sync完成后,我遇到了这个错误:
MyApp/MyAppFre/ build.gradle: failed to resolve ThirdPartyLibrary-0.1.0
MyApp/MyAppLibrary/ build.gradle: failed to resolve ThirdPartyLibrary-0.1.0
MyApp/MyAppPro/ build.gradle: failed to resolve ThirdPartyLibrary-0.1.0
有人可以帮我找出问题所在吗?
答案 0 :(得分:31)
其他项目发现:ThirdPartyLibraryWrapper
项目依赖于名为ThirdPartyLibrary-0.1.0:aar
的工件。 Java(和Android)库不会将它们自己的依赖项捆绑在一起 - 相反,它们只是发布它们的依赖项列表。然后,耗费项目不仅负责加载它直接依赖的库,而且还负责加载库所依赖的所有库。
这样做的最终结果是:MyAppFree
加载了:ThirdPartyLibraryWrapper
,然后看到:ThirdPartyLibraryWrapper
取决于ThirdPartyLibrary-0.1.0:aar
,因此也尝试将其加载到:MyAppFree
中。但是,ThirdPartyLibrary-0.1.0:aar
并不知道repositories
的生活地点......所以它失败了。
解决方案是在所有其他项目中放置类似的repositories {
flatDir {
dirs project(':ThirdPartyLibraryWrapper').file('libs')
}
}
块。试试这个:
project(...).file(...)
使用background-
方法将使您无需硬编码路径,而是使用Gradle DSL通过查找项目并让它动态地执行分辨率来解析文件系统路径。
