gradlew change jcenter() URL 用于 React Native 构建

Question

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

所以我们使用内部 Maven 存储库来获取工件。但是我在构建本机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本机 android 代码来构建，该代码引用 jcenter() 存储库（我不想覆盖 node_modules/react*/android/build.gradle 手动).

所以有一种方法可以用 gradle 覆盖 jcenter URL ?

我已经在我的用户主页中尝试 init script init.gradle（灵感来自文档）：

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，我得到了这个输出：

DEBUG : Repository https://my.enterprise.repo
DEBUG : Repository https://my.enterprise.repo
DEBUG : Repository https://my.enterprise.repo
DEBUG : Repository https://my.enterprise.repo
DEBUG : Repository https://my.enterprise.repo

插件似乎没有拦截 jcenter 存储库...

在您的初始化脚本中，您正在对项目的存储库设置约束。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/...”而不是从您的企业存储库下载一些依赖项：我猜这些是您使用的插件的依赖项适用于您的构建脚本。因此，除了项目的依赖项存储库之外，您还必须配置项目的构建脚本存储库。以下代码应该可以工作（但我无法测试）：

apply plugin: EnterpriseRepositoryPlugin

class EnterpriseRepositoryPlugin implements Plugin<Gradle> {

    private static String ENTERPRISE_REPOSITORY_URL = "https://repo.gradle.org/gradle/repo"

    def configRepositories = { ->
        // Remove all repositories not pointing to the enterprise repository url
        all { ArtifactRepository repo ->
            if (!(repo instanceof MavenArtifactRepository) ||
                    repo.url.toString() != ENTERPRISE_REPOSITORY_URL) {
                println "Repository ${repo.name} removed. Only $ENTERPRISE_REPOSITORY_URL is allowed"
                remove repo
            }
        }
        // add the enterprise repository
        jcenter {
            name "BintrayJCenter"
            url ENTERPRISE_REPOSITORY_URL
        }
    }

    void apply(Gradle gradle) {    

        gradle.allprojects { project ->
            // ONLY USE ENTERPRISE REPO FOR DEPENDENCIES
            project.repositories(configRepositories)
            // Only use enterprise repo for plugins classpath as well.
            project.buildscript.repositories(configRepositories)
        }
    }

}
