从Nexus3下载单个/最新资产（JAR）

Question

我正在尝试从我当地的Nexus repo下载最新/最新资产（JAR）。我正在使用Nexus Swagger UI。它有一个GET方法可供下载，

GET /beta/search/assets/download

问题是..我在repo中有很多资产，它会出错，

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

如何优化我的搜索＆amp;获取最新/最新的JAR？

仅供参考。目前，我在回购中拥有20多个资产，下面我展示其中两个......

Answer 1

您可以使用工件redirtect（curl -L能够遵循重定向）而不是使用搜索：/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。

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

Answer 2

在v3（确切地说是3.17.0）中使用REST API，以下方法应该可以获取任何lib的最新版本：

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