无法在jsp中显示maven项目版本信息

Question

我试图在我的JSP页面上显示maven版本信息。我GOOGLE了这一点，并找到了许多不同的解决方案，有些在博客文章和一些在stackoverflow其中大部分是非常老的历史可以追溯到2009年。我选择了一个在stackoverflow（How can I in a jsp page get maven project version number?），并试图通过放入下面的代码片段在我的pom中，并在我的JSP中调用$ {project.version}但它不起作用。

我错过了什么吗？

<plugin> 
     <groupId>org.apache.maven.plugins</groupId> 
     <artifactId>maven-war-plugin</artifactId> 
     <version>2.3</version> 
     <configuration> 
      <failOnMissingWebXml>true</failOnMissingWebXml> 
      <webResources> 
       <resource> 
        <directory>src/main/webapp</directory> 
        <filtering>true</filtering> 
       </resource> 
      </webResources> 
     </configuration> 
    </plugin> 

但是，我没有看到显示的版本。不知道我错过了什么。

你尝试这个解决方案？

Mayber你可以在代码中检索它，并在你的jsp上获取它。
