从 Nexus3 下载 single/latest 资产 (JAR)

Question

我正在尝试从本地 Nexus 存储库下载 latest/newest 资产 (JAR)。我正在使用 Nexus Swagger UI。它有一个 GET 方法可以下载，

GET /beta/search/assets/download

问题是..我在回购协议中有很多资产，它给出了一个错误，

Search returned multiple assets, please refine search criteria to find a single asset

如何优化我的搜索并获得 latest/newest JAR？

仅供参考.. 目前，我在回购协议中有 20 多个资产，下面我展示了其中两个..

Answer 1

不使用搜索，您可以使用工件重定向（curl -L 能够跟随重定向）：/artifact/maven/redirect

curl -L "http://repository.sonatype.org/service/local/artifact/maven/redirect?r=central-proxy&g=log4j&a=log4j&v=LATEST" -o log4j.jar

但是，might not be available for Nexus 3 yet。

在那种情况下，您需要download and parse first the maven-metadata.xml。
您可以从那里提取最新的标签。

2018 年 2 月，NEXUS-12469 asks the same question, and references NEXUS-14407：'Latest' 的 REST 搜索和下载，2019 年第 4 季度 3.16 发布。

Extend the search & download service so that users can sort the search results by 'latest version'.

Examples:

http://localhost:8081/service/rest/v1/search/assets/download?repository=maven-central&group=junit&name=junit&sort=version&prerelease=false

curl -L -o myartifact.tar.gz -u xxx:xxx "http://localhost:8080/service/rest/v1/search/assets/download?sort=version&direction=desc&repository=maven-snapshots&maven.groupId=bla.bla.bla&maven.artifactId=bla-bla&maven.extension=tar.gz

所以组合：

API 端点 assets/download
sort=version修饰符

Answer 2

使用 v3 中的 REST API（确切地说是 3.17.0），以下应该可以获取任何库的最新版本：

/service/rest/v1/search/assets/download?sort=version&maven.artifactId=artifactId&maven.groupId=groupId&maven.extension=jar
