Maven依赖:使用基本版本

标签: maven maven-dependency-plugin maven-metadata

我正在尝试通过maven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:

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

我想下载这样的工件:

 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-Dmdep.useBaseVersion选项,但这只保存了下载的工件和基本版本。

编辑:

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

行家-metadata.xml中:

<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-DgeneratePom=true选项部署工件,我只能使用基本版本号从存储库下载最新工件。
