Gradle 找不到 org.apache.commons :commons-imaging

Question

Gradle 无法解析 org.apache.commons:commons-imaging ，但它在提供的所有 3 个存储库中都可用:

http://jump-pilot.sourceforge.net/repository

https://repo.adobe.com/nexus/content/repositories/public/

https://repository.apache.org/content/repositories/snapshots/

这部分日志很有趣，Gradle 只在 jcenter 中查找和本地文件系统:

https://jcenter.bintray.com/org/apache/commons/commons-imaging/1.0-SNAPSHOT/maven-metadata.xml https://jcenter.bintray.com/org/apache/commons/commons-imaging/1.0-SNAPSHOT/commons-imaging-1.0-SNAPSHOT.pom https://jcenter.bintray.com/org/apache/commons/commons-imaging/1.0-SNAPSHOT/commons-imaging-1.0-SNAPSHOT.jar file:/Users/user/Library/Android/sdk/extras/android/m2repository/org/apache/commons/commons-imaging/1.0-SNAPSHOT/maven-metadata.xml file:/Users/user/Library/Android/sdk/extras/android/m2repository/org/apache/commons/commons-imaging/1.0-SNAPSHOT/commons-imaging-1.0-SNAPSHOT.pom file:/Users/user/Library/Android/sdk/extras/android/m2repository/org/apache/commons/commons-imaging/1.0-SNAPSHOT/commons-imaging-1.0-SNAPSHOT.jar file:/Users/user/Library/Android/sdk/extras/google/m2repository/org/apache/commons/commons-imaging/1.0-SNAPSHOT/maven-metadata.xml file:/Users/user/Library/Android/sdk/extras/google/m2repository/org/apache/commons/commons-imaging/1.0-SNAPSHOT/commons-imaging-1.0-SNAPSHOT.pom file:/Users/user/Library/Android/sdk/extras/google/m2repository/org/apache/commons/commons-imaging/1.0-SNAPSHOT/commons-imaging-1.0-SNAPSHOT.jar

Answer 1

android 项目中有 2 个 build.gradle 文件:一个在主项目文件夹中，一个在 app 文件夹中。存储库应在项目文件夹内的 allprojects 块下定义。在这里，我的 build.gradle 示例成功构建了 apache commons 镜像。

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

}

allprojects {
    repositories {
        jcenter()
        maven { url "http://jump-pilot.sourceforge.net/repository" }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
