如何在Gradle生成的POM中声明存储库

问题描述

我正在GitHub上的一个自我维护的maven仓库发布一个工件A.该项目具有几个传递依赖关系B，C，D，托管在不同的存储库中。依赖项B，C，D在生成p的pom.xml（uploadArchives）的渐变中指定，但不指定到存储库的路径。因此，当将A指定为另一个项目中的依赖关系时，传递依赖关系B，C，D不被下载。

是否可以告诉毕业者将A的pom.xml中的B，C，D的maven存储库。

解决方案

这样做的方法是定制生成的POM。这是一个例子，假设 maven 插件用于发布：

  uploadArchives {
 repositories {
 mavenDeployer {
 //将更多信息添加到生成的POM 
 //语法映射1：1到POM语法
 pom.project {
 //还可以以编程方式生成
 //，基于build 
资源库中声明的repos {
 repository {
 id'myrepo'
 url'http // my.repo.com'
} 
} 
} 
} 
} 
} 
  

新的孵化 maven-publish 插件提供了一个类似的钩子。

请注意，Gradle本身不符合在解析依赖关系时在POM中声明的存储库，而只是声明为b的存储库你的建设。另请查看。

I am publishing an artifact A to a self maintained maven repository on GitHub. The project has several transitive dependencies B, C, D which are hosted in different repositories. The dependencies B, C, D are specified in the gradle generated pom.xml (uploadArchives) of A but not the paths to the repositories. Therefore, the transitive dependencies B, C, D are not downloaded when A is specified as a dependency in another project.

Is it possible to tell gradle to include the urls of the maven repositories of B, C, D in the pom.xml of A?

解决方案

The way to do this is to customize the generated POM. Here is an example, assuming that the maven plugin is used for publishing:

uploadArchives {
    repositories {
        mavenDeployer {
            // add further information to the generated POM
            // syntax maps 1:1 to POM syntax
            pom.project {
                // could also generate this programmatically
                // based on the repos declared in the build
                repositories {
                    repository {
                        id 'myrepo'
                        url 'http//my.repo.com'
                    }
                }
            }
        }
    }
}

The new, incubating maven-publish plugin offers a similar hook.

Note that Gradle itself doesn't honor repositories declared in POMs when resolving dependencies, but only repositories declared by your build. Also check out http://www.sonatype.com/people/2009/02/why-putting-repositories-in-your-poms-is-a-bad-idea/.
