我正在尝试使用 Maven 通过命令行下载一些工件。我只知道工件的基本版本,但它们在 nexus 存储库中有一个单独的时间戳。

例如:

该工件在 nexus 存储库中com.mycompany.subject:any-artifact:3.0.0-SNAPSHOT:war:plugins具有以下坐标。com.mycompany.subject:any-artifact:3.0.0-20161212.140040-1:war:plugins

我想像这样下载工件:

 mvn org.apache.maven.plugins:maven-dependency-plugin:2.10:copy -Dartifact=com.mycompany.subject:any-artifact:3.0.0-SNAPSHOT:war:plugins -DoutputDirectory=./my-tmp 

我在文档中找到了该-Dmdep.useBaseVersion选项,但这只会将下载的工件与基本版本一起保存。

编辑:

问题是,我只知道工件的基本版本,例如 3.0.0-SNAPSHOT,当我尝试像上面那样从 nexus 下载它时,它失败了,因为 nexus 中的版本带有时间戳。

maven-metadata.xml:

<metadata>
  <groupId>com.mycompany.subject</groupId>
  <artifactId>any-artifact</artifactId>
  <versioning>
    <versions>
        <version>3.0.0-SNAPSHOT</version>
    </versions>
    <lastUpdated>20161214160043</lastUpdated>
  </versioning>
</metadata>

问题是该项目在存储库中没有 pom.xml,因此 maven 可能需要带有时间戳等的确切版本号。

现在,我使用该选项部署工件,-DgeneratePom=true并且我只能使用基本版本号从存储库下载最新的工件。
