Maven project.version - 使用子pom版本

Question

我需要在jsp上获取项目版本和构建日期。

以下是我需要使用该版本的pom：

   <parent>
        <groupId>a.b</groupId>
        <artifactId>c</artifactId>
        <version>0.1-SNAPSHOT</version>
    </parent>

    <modelVersion>4.0.0</modelVersion>
    <groupId>a.b.c</groupId>
    <artifactId>c-uiWeb</artifactId>
    <version>1.2-SNAPSHOT</version>

JSP：

<br/><div align="right" style="display:none">Project Version:${project.version} - ${timestamp} </div><br/>

现在版本显示为＆＃34; 0.1-SNAPHOT＆＃34;。我需要它来显示＆＃34; 1.2-SNAPSHOT＆＃34;。我错过了什么？请帮忙

修改

项目结构：c-uiWeb

src -> main -> java

src --> main -> resources

src -> main -> webapp -> WEB-INF -> jsp

全程：
