我和maven有一个奇怪的问题。我正在使用过滤选项将一些版本信息放入属性文件中。然后我将其包含在jar文件中，以便“帮助/关于”可以告诉我一些有用的东西。我遇到的问题是jar文件中的版本是之前的版本。因此，如果我在0930运行构建，而在0940运行另一个构建，那么在0940生成的jar中的属性文件的版本将具有0930的构建时间。我也使用buildNumber插件，但是这样无论我是否启用它都会出现问题。
更奇怪的是，当我在eclipse中运行我的构建并运行程序时，“旧”文件显示在help / about上，但是当我“刷新”（F5）eclipse项目并重新启动时运行程序，我得到正确的版本。那么maven是否会以某种方式采用eclipse版本？为什么你需要在eclipse中“刷新”才能让它拥有最新的版本。
无论如何，我的pom.xml是

首先要激活对资源的过滤，如下所示：
<build>
<resources>
<resource>
<directory>src/main/resources/</directory>
<filtering>true</filtering>
</resource>
</resources>
...
</build>
这将激活对src/main/resources文件夹（和子文件夹）中所有文件的过滤。有时您只需要过滤有限数量的文件。在这样的sutuations中只需将这些文件放入子文件夹并适当地更改上述配置。
接下来是定义一个属性文件（在src/main/resources文件夹中），其中包含您需要的所有信息，如下所示：
版本= $ {project.version} buildNumber = $ {} buildNumber 构建时= $ {maven.build.timestamp}
此外，buildnumber-maven-plugin的配置如下：
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>buildnumber-maven-plugin</artifactId>
<version>1.2</version>
<executions>
<execution>
<phase>validate</phase>
<goals>
<goal>create</goal>
</goals>
</execution>
</executions>
<configuration>
<doCheck>false</doCheck>
<doUpdate>false</doUpdate>
<revisionOnScmFailure>UNKNOWN</revisionOnScmFailure>
<format>{0,date,yyyy-MM-dd_HH-mm}_{1}</format>
<items>
<item>timestamp</item>
<item>${user.name}</item>
</items>
</configuration>
</plugin>
之后，您可以简单地删除maven-replacer-plugin的用法，这些插件在这种简单的场景中是不需要的。
