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

Question

Gradle无法解析org.apache.commons:commons-imaging，但在所有提供的三个存储库中都可用：

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

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

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

日志的这一部分很有趣，Gradle仅查找jcenter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 文件：/Users/user/Library/Android/sdk/extras/android/m2repository/org/apache/commons/commons-imaging/1.0-SNAPSHOT/maven-metadata.xml文件：/ Users / user / Library / Android / sdk /extras/android/m2repository/org/apache/commons/commons-imaging/1.0-SNAPSHOT/commons-imaging-1.0-SNAPSHOT.pom文件：/ Users / user / Library / Android / sdk / extras / android / m2repository / org /apache/commons/commons-imaging/1.0-SNAPSHOT/commons-imaging-1.0-SNAPSHOT.jar文件：/ Users / user / Library / Android / sdk / extras / google / m2repository / org / apache / commons / commons-imaging /1.0-SNAPSHOT/maven-metadata.xml文件：/Users/user/Library/Android/sdk/extras/google/m2repository/org/apache/commons/commons-imaging/1.0-SNAPSHOT/commons-imaging-1.0-SNAPSHOT .pom文件：/Users/user/Library/Android/sdk/extras/google/m2repository/org/apache/commons/commons-imaging/1.0-SNAPSHOT/commons-imaging-1.0-SNAPSHOT.jar

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。这里是我的 build.gradle 的示例，它成功构建了 apache commons 映像。

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
}
