android - Gradle 模块和 git 子模块

Question

我有一个名为 toolkit 的库项目，它有两个模块 core 和 database，配置如下:

设置.gradle

include ':core'
include ':database' 

核心build.gradle

dependencies {
    compile 'com.android.support:support-v4:20.+'
    compile 'com.jakewharton:butterknife:5.1.+'
    compile 'com.google.code.gson:gson:2.2.+'
    compile 'uk.co.chrisjenx:calligraphy:0.7.+'
    compile files('libs/flurry-3.4.0.jar')
}

数据库build.gradle

dependencies {
    compile project(':core')
}

在这个库项目上运行我的测试没问题，但我想将这个库添加为其他项目的 git 子模块，这个项目有以下配置:

设置.gradle

include ':app-tablet'
include 'libraries:float-hint'
include 'libraries:toolkit:core'
include 'libraries:toolkit:database'
include 'libraries:twoway-view:TwoWayView'

应用构建.gradle

dependencies {
    compile 'com.astuetz:pagerslidingtabstrip:1.0.1'
    compile 'com.google.android.gms:play-services:+'
    compile 'com.j256.ormlite:ormlite-android:4.48'
    compile 'com.jayway.android.robotium:robotium-solo:5.2.1@jar'
    compile 'com.squareup.dagger:dagger:1.2.+'
    compile 'com.squareup.picasso:picasso:2.1.1@jar'
    compile files('libs/YouTubeAndroidPlayerApi.jar')
    compile project(':libraries:float-hint')
    compile project(':libraries:porquenao-toolkit:core')
    compile project(':libraries:porquenao-toolkit:database')
    compile project(':libraries:twoway-view:TwoWayView')
}

当我尝试编译时，我得到以下信息:

$  gradlew assembleDebug -d

我知道问题出在路径 :core 和 libraries:toolkit:core 但如何适本地解决这个问题？

Answer 1

您的应用程序 gradle 文件存在命名问题。

settings.gradle 有:

包含'libraries:toolkit:core'

build.gradle 有:

compile project(':libraries:porquenao-toolkit:core')

假设您修复了这个问题，您仍然会遇到错误。

数据库模块将尝试编译 ":core"，但在应用程序中使用时，核心模块具有不同的路径:":libraries:porquenao-toolkit:core "

解决此问题的一种方法是将核心库作为“:core”包含在两个项目中，但为其提供不同的项目路径。

您的 settings.gradle 文件看起来像:

工具包:

include ':core'
project(':core').projectDir = new File(rootDir, 'core')

应用:

include ':core'
project(':core').projectDir = new File(rootDir, 'libraries/porquenao-toolkit/core')
