我的java / maven项目“ testproject”与我的jenkins和nexus回购挂钩：

我的pom.xml看起来像：

....    
<distributionManagement>
    <!-- use the following if you're not using a snapshot version. -->
    <repository>
        <id>nexus</id>
        <name>RepositoryProxy</name>
        <url>http://nexus:8080/nexus/content/repositories/releases</url>
    </repository>
    <!-- use the following if you ARE using a snapshot version. -->
    <snapshotRepository>
        <id>nexus</id>
        <name>RepositoryProxy</name>
        <url>http://nexus:8080/nexus/content/repositories/snapshots</url>
    </snapshotRepository>
</distributionManagement>
......

在我的詹金斯设置中，我有：

Build - maven3 - clean deploy

正如预期的那样，jenkins将工件上传到Nexus。查看jenkins build的控制台输出，如下所示：

问题是 ：

鉴于我在pom.xml中指定的版本是

<version>0.1-SNAPSHOT</version>

1. jenkins为何将testproject- 0.1-20120509.161644-74 .jar 上传到Nexus？20120509.161644-74产品从哪里来？

2. 如果时间戳 20120509.161644-74 是jenkins在上传之前生成的，我可以配置它的格式吗？我想要类似testproject-01-$ {timestamp}-$ {reversionId} .jar的文件
