Gradle自定义存储库和依赖项解析

Question

我正在开发的一个项目需要scribe-java和crashlytics库。这两个库都可以从自定义存储库中获得。

build.gradle看起来像这样：

buildscript {
    repositories {
        maven { url 'http://download.crashlytics.com/maven' }
    }

    dependencies {
        classpath 'com.crashlytics.tools.gradle:crashlytics-gradle:1.+'
    }
}
apply plugin: 'android'
apply plugin: 'crashlytics'
repositories {
    // is required by Crashlytics library
    maven { url 'http://download.crashlytics.com/maven' }
    // is required by Scribe library
    maven { url 'https://raw.github.com/fernandezpablo85/scribe-java/mvn-repo/' }
}

....

dependencies {

    compile 'com.android.support:support-v4:+'

    compile 'com.crashlytics.android:crashlytics:1.+'
    ...
    // OAuth/OAuth2
    compile 'org.scribe:scribe:1.3.6'
    ...
}

有了这样的设置，存储库解析在构建过程中变得混乱，这样gradle就会尝试从不合适的存储库中解析工件：

它尝试从脚本存储库中检索crashlytics文件。

Answer 1

将按其声明的顺序搜索存储库，直到找到依赖项为止。如果在脚本存储库中搜索crashlytics库，则意味着在crashlytics存储库中找不到它。
