如何指定“pig-0.13.0-h2.jar"build.gradle 中的依赖? [英] How to specify "pig-0.13.0-h2.jar" dependency in build.gradle?

问题描述

为了在我的项目中指定一个 Maven 依赖项，我提供了一个 name、一个 group id 和一个 version.这对于我项目中的每个依赖项来说已经足够了，保存一个.Pig 在同一个工件中有多个 jar(不确定我是否有正确的命名法；我对 Maven 还是比较陌生)，但我只需要一个.

To specify a Maven dependency in my project, I provide a name, a group id, and a version. This has been enough for every dependency in my project, save one. Pig has multiple jars in the same artifact (not sure if I have the proper nomenclature; I'm still rather new to Maven), but I only need one.

具体来说，我需要pig-0.13.0-h2.jar.但是，当我提供依赖项

Specifically, I need pig-0.13.0-h2.jar. However, when I provide the dependency

compile "org.apache.pig:pig:0.13.0"

在我的 build.gradle 中，只有 pig-0.13.0.jar、pig-0.13.0-sources.jar 和pig-0.13.0.pom 已下载.我需要*-h2.jar"，因为这是与我的 Hadoop 版本一起使用的正确方法.

in my build.gradle, only pig-0.13.0.jar, pig-0.13.0-sources.jar, and pig-0.13.0.pom are downloaded. I need the "*-h2.jar", because that's the correct one to work with my version of Hadoop.

有没有办法告诉 Gradle(通常还有 Maven 或其他任何东西)我的编译依赖项需要这个确切的 jar，并且只有这个应该包含在类路径中?

Is there a way to tell Gradle (and, generally, Maven or whatever) that my compile dependency requires this exact jar, and that only this one should be included in the classpath?

推荐答案

你需要的是指定分类器.以下脚本将完成这项工作:

What you need is to specify the classifier. The following script will do the job:

apply plugin: 'java'

repositories {
   mavenCentral()
}

dependencies {
   compile "org.apache.pig:pig:0.13.0:h2"
}

task copyDeps(type: Copy) {
   from configurations.compile
   into 'deps'
}
