Maven API 搜索未检索 Google 依赖项

Question

当我使用 Maven API 搜索功能时，它可以很好地处理 Central repo 中的依赖项（例如 retrofit），但是，它不会从 Google repo 中检索依赖项（例如 play-services-加）。尽管它们都可以在网络搜索中找到 https://mvnrepository.com.

网络搜索结果：
https://mvnrepository.com/artifact/com.squareup.retrofit2/retrofit/2.8.2
API URL:
API Link
API 结果：
{"responseHeader":{"status":0,"QTime":0,"params":{"q":"g:\"com.squareup.retrofit2\" AND a:\"retrofit\" AND v:\"2.8.2\"","core":"","indent":"off","fl":"id,g,a,v,p,ec,timestamp,tags","start":"","sort":"score desc,timestamp desc,g asc,a asc,v desc","rows":"20","wt":"json","version":"2.2"}},"response":{"numFound":1,"start":0,"docs":[{"id":"com.squareup.retrofit2:retrofit:2.8.2","g":"com.squareup.retrofit2","a":"retrofit","v":"2.8.2","p":"jar","timestamp":1589829834000,"ec":["-sources.jar","-javadoc.jar",".jar",".pom"],"tags":["safe","client","android","http","java","type"]}]}}

网络搜索结果：
https://mvnrepository.com/artifact/com.google.android.gms/play-services-plus/16.0.0
API URL:
API Link For Google Services
API 结果：
{"responseHeader":{"status":0,"QTime":0,"params":{"q":"g:\"com.google.android.gms\" AND a:\"play-services-plus\" AND v:\"16.0.0\"","core":"","indent":"off","fl":"id,g,a,v,p,ec,timestamp,tags","start":"","sort":"score desc,timestamp desc,g asc,a asc,v desc","rows":"20","wt":"json","version":"2.2"}},"response":{"numFound":0,"start":0,"docs":[]}}

如何在 Central repo 之外检索依赖项，我需要以编程方式进行，例如API?

Answer 1

您需要添加 Google maven 存储库，更新您的 settings.xml 文件以将其包含为：

        <repository>
            <id>google</id>
            <url>https://maven.google.com/</url>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>

或您的 build.gradle 文件：

repositories {
    google()
}

mvnrepository.com 详细说明了依赖项可用的位置，如果您重新访问 url，它会在 'Compile Dependencies' 部分的上方详细说明

要以编程方式搜索'Google's Maven Repository'，您可以搜索组-index.xml 通过 https://maven.google.com/group_path/group-index.xml

寻找您要寻找的神器

所以在你的情况下你会搜索：

https://maven.google.com/com/google/android/gms/group-index.xml

要获取您选择的 artifact/version 的发布数据（pom 或 aar），您可以使用以下语法执行 GET：https://maven.google.com/group_path/library/version/library-version.ext（其中 ext 是 pom 或 aar）

因此，在您的情况下，您将为以下对象执行 GET：

https://maven.google.com/com/google/android/gms/play-services-plus/16.0.0/play-services-plus-16.0.0.pom

or

https://maven.google.com/com/google/android/gms/play-services-plus/16.0.0/play-services-plus-16.0.0.aar
