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>

答案 0 :(得分:0)
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。
