关于android：gradlew更改React Native构建的jcenter()URL


gradlew change jcenter() URL for React Native build

我试图为Android构建React Native应用程序，但是在我的企业中，外部存储库被阻止(不允许外部网络)。

因此，我们使用内部Maven存储库来获取工件。
但是我在构建React Native应用程序时遇到了一些问题，因为具有节点模块依赖项的项目具有要引用jcenter()存储库的本机Android代码(我不想覆盖node_modules / react * / android / build.gradle手动)。

因此有一种方法可以用gradle覆盖jcenter URL？

我已经在我的用户主目录中尝试过init脚本init.gradle(从doc中得到启发)：

apply plugin:EnterpriseRepositoryPlugin

class EnterpriseRepositoryPlugin implements Plugin<Gradle> {

    private static String ENTERPRISE_REPOSITORY_URL ="https://my.enterprise.repo"

    void apply(Gradle gradle) {
        // ONLY USE ENTERPRISE REPO FOR DEPENDENCIES
        gradle.allprojects{ project ->
            project.repositories {

                // Remove all repositories not pointing to the enterprise repository url
                all { ArtifactRepository repo ->
                    project.logger.lifecycle"DEBUG : Repository ${repo.url}"
                    if (!(repo instanceof MavenArtifactRepository) ||
                          repo.url.toString() != ENTERPRISE_REPOSITORY_URL) {
                        project.logger.lifecycle"Repository ${repo.url} removed. Only $ENTERPRISE_REPOSITORY_URL is allowed"
                        remove repo
                    }
                }

                // add the enterprise repository
                jcenter {
                    name"BintrayJCenter"
                    url ENTERPRISE_REPOSITORY_URL
                }
            }
        }
    }
}

但是当我开始gradlew时，我得到的输出是：

插件似乎没有拦截jcenter存储库...

在初始化脚本中，您正在项目的存储库上设置约束。但是，正如您在错误消息中看到的那样，Gradle仍在尝试从" https：//repo1.maven.org / ..."而不是从您的企业仓库下载某些依赖项：我想这些是您所用插件的依赖项正在应用于您的构建脚本。
因此，除了项目的依赖项存储库之外，还必须配置项目的buildscript存储库。
以下代码应该可以工作(但是我无法测试)：
