Android Gradle将外部库和嵌套外部库添加到项目中

Question

如何将外部库和嵌套外部库添加到android项目中？

---

我的项目结构（不允许更改）

• 应用程序/
  • App1的/
    • 的build.gradle
    • settings.gradle
  • 库/
    • LIBRARY1 /
      • build.grade
      • settings.gradle
    • library2 /
      • build.grade
      • settings.gradle
    • library3 /
      • build.grade
      • settings.gradle
    • library4 /
      • build.grade
      • settings.gradle

App1的

App1的/的build.gradle

buildscript {
    ...
}

apply plugin: 'android'

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile project(':..:libraries:library1')
    compile project(':..:libraries:library2')
    compile project(':..:libraries:library3')
    compile project(':..:libraries:library4')
}

android {
    ...
}

App1并不直接依赖library3或library4，但如果我不将它们包含在build.gradle文件和{{1}的依赖项中，它会抱怨文件。所以，我把它们包括在内只是为了阻止它抱怨。

App1的/ settings.gradle

settings.gradle

---

LIBRARY1

LIBRARY1 /的build.gradle

include ':'
include '..:libraries:library1'
include '..:libraries:library2'
include '..:libraries:library3'
include '..:libraries:library4'

LIBRARY1 / settings.gradle

buildscript {
    ...
}

apply plugin: 'android-library'

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile project(':..:library3')
    compile project(':..:library4')
}

android {
    ...
}

---

library2..4

library2..4 /的build.gradle

include ':'
include '..:library3'
include '..:library4'

library2..4 / settings.gradle

buildscript {
    ...
}

apply plugin: 'android-library'

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
}

android {
    ...
}

在include ':' 上尝试gradlew clean build时，我收到以下错误：

App1

第15行是FAILURE: Build failed with an exception. * Where: Build file '/home/user/projects/branches/branch1/Apps/libraries/library1/build.gradle' line: 15 * What went wrong: A problem occurred evaluating project ':..:library:library1'. > Project with path ':..:library3' could not be found in project ':..:library:library1'. 文件中的compile project(':..:library3')。

如何将外部库和嵌套外部库添加到android项目中？

Answer 1

在顶级settings.gradle（App1 / settings.gradle）文件中为每个库执行类似的操作

include ':library1'   
include ':library2'   
include ':library3'   
include ':library4'   

project(':library1').projectDir = new File(rootProject.projectDir, '../libraries/library1')
project(':library2').projectDir = new File(rootProject.projectDir, '../libraries/library2')
project(':library3').projectDir = new File(rootProject.projectDir, '../libraries/library3')
project(':library4').projectDir = new File(rootProject.projectDir, '../libraries/library4')

删除其他settings.gradle文件，您不需要它们

然后在每个构建脚本中，您只需要使用

compile project (':library1')
compile project (':library2')
etc....

如上所述，只需在根项目（App1）中使用一个settings.gradle文件。

然后从App1文件夹运行gradlew clean :library1:build以验证library1是否正确构建。

关于App1抱怨丢失库3＆amp; 4，您确定应用程序中没有直接引用这些库的代码，或者在编译library1时找不到库。单独构建每个库以验证它们都构建正常。

Answer 2

一个问题。 你需要这个依赖树吗？

--- App
   |--- Library 2
   |--- Library 1
       |--- Library 3
       |--- Library 4

如果是，您的应用程序不需要导入库3和4.这些依赖项可通过库1获得。

关于settings.gradle文件。为什么每个模块中有一个？此文件仅用于根项目（如Eclipse工作区）以引用您的模块（App，Library 1，Library 2等）

这对你有帮助吗？

我正在为相对路径做这件事：

include '..:ambilWarna'
include '..:excel'
include '..:pdfjet'
include '..:commons'
include '..:volley'


include  ':odb2'
include  ':azure'

include ':carBase'
include ':fuelTrackerLib'
include ':comsourcecastlelogbook'
