如何向 Maven 工件添加时间戳信息? [英] How do I add time-stamp information to Maven artifacts?

问题描述

我正在升级一个大型构建系统以使用 Maven2 而不是 Ant，我们有两个相关的要求，我坚持:

1. 我们需要生成一个带时间戳的工件，所以是包的一部分阶段(或任何地方)，而不是构建

   project-1.0-SNAPSHOT.jar

   我们应该建设

   project-1.0-20090803125803.jar

   (其中20090803125803 只是 jar 的 YYYYMMDDHHMMSS 时间戳建).

   唯一真正的要求是时间戳是生成文件的文件名.

2. 相同的时间戳必须包含在 version.properties 文件中在生成的 jar 中.

此信息包含在您运行时生成的 pom.properties 中，例如，mvn package 但被注释掉了:

#由Maven生成#Mon August 03 12:57:17 PDT 2009

任何关于从哪里开始的想法都会有所帮助！谢谢！

解决方案

Maven 2.1.0-M1 或更新版本已经内置了特殊变量 maven.build.timestamp.

<finalName>${project.artifactId}-${project.version}-${maven.build.timestamp}</finalName></build>

有关详细信息，请参阅 Maven 文档.

<小时>

对于较旧的 Maven 版本，请查看 maven-timestamp-plugin 或buildnumber-maven-plugin.

如果您使用 maven-timestamp-plugin，您可以使用类似这样的东西来操作生成的工件名称.

<finalName>${project.artifactId}-${project.version}-${timestamp}</finalName></build>

这个 buildnumber-maven-plugin 的配置应该创建一个包含时间戳值的 ${timestamp} 属性.似乎没有办法直接使用此插件创建 version.properties 文件.

<预><代码><配置><format>{0,date,yyyyMMddHHmmss}</format><物品><item>时间戳</item></物品></配置>

这些三个 网站也值得一试.

I am upgrading a large build-system to use Maven2 instead of Ant, and we have two related requirements that I'm stuck on:

1. We need to generate a time-stamped artifact, so a part of the package phase (or wherever), instead of building

   project-1.0-SNAPSHOT.jar
   

   we should be building

   project-1.0-20090803125803.jar
   

   (where the 20090803125803 is just a YYYYMMDDHHMMSS time-stamp of when the jar is built).

   The only real requirement is that the time-stamp be a part of the generated file's filename.

2. The same time-stamp has to be included within a version.properties file inside the generated jar.

This information is included in the generated pom.properties when you run, e.g., mvn package but is commented out:

#Generated by Maven
#Mon Aug 03 12:57:17 PDT 2009

Any ideas on where to start would be helpful! Thanks!

解决方案

Maven versions 2.1.0-M1 or newer have built in special variable maven.build.timestamp.

<build>
  <finalName>${project.artifactId}-${project.version}-${maven.build.timestamp}</finalName>
</build>

See Maven documentation for more details.

For older Maven versions a look at maven-timestamp-plugin or buildnumber-maven-plugin.

If you use maven-timestamp-plugin, you can use something like this to manipulate resulting artifact name.

<build>
   <finalName>${project.artifactId}-${project.version}-${timestamp}</finalName>
</build>

And this configuration for buildnumber-maven-plugin should create a ${timestamp} property which contains the timestamp value. There doesn't seem to be a way to create the version.properties file directly with this plugin.

<configuration>
   <format>{0,date,yyyyMMddHHmmss}</format>
   <items>
      <item>timestamp</item>
   </items>

</configuration>
