Maven在jar中過濾的文件已過期

Question

我有一個Maven的奇怪問題。我正在使用過濾選項將某些版本信息放入屬性文件中。然後我將它包含在jar文件中，以便「Help/About」可以告訴我一些有用的信息。我遇到的問題是jar文件中的版本是以前的版本。因此，例如，如果我在0930運行構建，而在0940運行另一個構建，那麼在0940生成的jar中的屬性文件版本將具有0930的構建時間。我也使用buildNumber插件，但是此問題是否存在，無論我是否啓用它。

更奇怪的是，當我從eclipse中運行我的構建並運行程序時，「舊」文件顯示在幫助/ about上，但是當我「刷新」（F5）eclipse項目並重新運行程序，我會得到正確的版本。那麼maven是否會以某種方式取得日食版呢？爲什麼你需要在eclipse中「刷新」以獲得最新的版本。

不管怎樣，我的pom.xml是

Answer 1

的第一件事就是激活您的資源，像這樣的過濾：

<build> 
    <resources> 
     <resource> 
     <directory>src/main/resources/</directory> 
     <filtering>true</filtering> 
     </resource> 

    </resources> 
    ... 
    </build> 

這將激活濾波這是在所有文件文件夾（和子文件夾）src/main/resources。有時您只需要對有限數量的文件進行過濾。在這樣的解決方案中，只需將這些文件放入一個子文件夾並適當地更改上述配置即可。 下一步是定義一個屬性文件（文件夾src/main/resources），其中包括你需要這樣的所有信息：

版本= $ {} project.version buildNumber = $ {} buildNumber 構建時= $ {maven.build。時間戳}

而且做的buildnumber-maven-plugin這樣的結構：

<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> 

之後，你可以簡單的刪除Maven的替代品 - 插件，你不這樣簡單的場景需要的usuage。
