jsp中无法显示maven项目版本信息

Question

我正在尝试在我的 JSP 页面上显示 maven 版本信息。我对此进行了谷歌搜索，并找到了许多不同的解决方案，一些在博客文章中，一些在 stackoverflow 上，其中大多数都可以追溯到 2009 年。我在 stackoverflow (How can I in a jsp page get maven project version number?) 上选择了一个并尝试通过在我的 pom 中放入以下代码 sn-p 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。

您尝试过这个解决方案吗？

也许您可以在代码中检索它并在您的 jsp 上获取它。

Retrieve version from maven pom.xml in code
