android - 在 gradle 中重构 Maven block

Question

我正在开发一个 android 项目，并且有许多使用相同凭据的自定义存储库:

repositories {
  maven {
    url "<url1>"
    credentials {
      username = "<username>"
      password = "<password>"
    }
  }

  maven {
    url "<url2>"
    credentials {
      username = "<username>"
      password = "<password>"
    }
  }

}

有没有办法定义一个方法( block ？)，这样我就可以定义一次用户名和密码，而不必每次都重复？我希望能够做到:

repositories {
  customMaven { url "<url1>"}
  customMaven { url "<url2>"}
}

如果我在这里使用的术语不正确，我深表歉意 - gradle 语法对我来说有点神秘。

@ToYonos 提供的第一个答案可以正常工作，但如果您正在寻找基于配置 block 的解决方案，您可以使用方法 MavenArtifactRepository maven(Action<? super MavenArtifactRepository> action)来自 RepositoryHandler类(see here)，如下:

// a Closure that builds an Action for configuring a MavenArtifactRepository instance
def customMavenRepo = { url ->
    return new Action<MavenArtifactRepository>() {
        void execute(MavenArtifactRepository repo) {
            repo.setUrl(url)
            repo.credentials(new Action<PasswordCredentials>() {
                void execute(PasswordCredentials credentials) {
                    credentials.setUsername("<username>")
                    credentials.setPassword("<password>")
                }
            });
        }
    };
}

// usage
repositories {
    jcenter()
    maven customMavenRepo("http://company.com/repo1")
    maven customMavenRepo("http://company.com/repo2")
    maven customMavenRepo("http://company.com/repo3")
}

EDIT 来自以下评论:Closure 的解决方案如下所示。我认为使用 curry这里需要方法(参见 Currying closure )，但也许还有其他方法可以简化...

// one closure with URL as parameter
ext.myCustomMavenClosure = { pUrl ->
    url pUrl
    credentials {
        username = "<username>"
        password = "<password>"
    }
}
// helper function to return a "curried" closure
Closure myCustomMaven (url){
    return myCustomMavenClosure.curry(url)
}

repositories {
    // use closure directly
    maven myCustomMavenClosure.curry ("http://mycompany.com/repo1")
    // or use helper method
    maven myCustomMaven("http://mycompany.com/repo2")
}
