Android Gradle将外部库和嵌套外部库添加到项目中

如何将外部库和嵌套外部库添加到android项目？

我的项目结构(不允许更改)

应用/

应用1 /

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

应用1 /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并不直接依赖于library3或library4,但是,它会抱怨,如果我不包括他们在在依赖build.gradle文件和settings.gradle文件.所以,我把它们包括在内只是为了阻止它抱怨.

应用1/settings.gradle

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

LIBRARY1

LIBRARY1 /的build.gradle

buildscript {
    ...
}

apply plugin: 'android-library'

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

android {
    ...
}

LIBRARY1/settings.gradle

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

library2..4

library2..4 /的build.gradle

buildscript {
    ...
}

apply plugin: 'android-library'

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

android {
    ...
}

library2..4/settings.gradle

include ':'

尝试时gradlew clean build,App1我收到以下错误:

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'.

15号线compile project(':..:library3')中library1/build.gradle的文件.
