Replace task in Maven Antrun Plugin

I am using antrun plugin in my maven build to replace a token @version@ in some of the JSP files with the application version. This is what I am doing:

<plugin>
    <artifactId>maven-antrun-plugin</artifactId>
    <version>1.6</version>
    <ex开发者_运维技巧ecutions>
        <execution>
            <phase>compile</phase>
            <configuration>
                 <target>
                      <echo>${displayVersion}</echo>
                      <replace file="src/main/webapp/admin/decorators/default.jsp" token="@version@" value="${displayVersion}"/>
                 </target>
            </configuration>
            <goals>
                <goal>run</goal>
            </goals>
        </execution>
    </executions>
</plugin>

I am passing displayVersion as a parameter to maven

mvn clean install -DdisplayVersion="Version-1.1"

And this is the console output for Antrun Plugin

[INFO] [antrun:run {execution: default}]
[INFO] [antrun:run {execution: default}]  
[INFO] Executing tasks  
main:  
[echo] 9.4_70  
[INFO] Executed tasks

Although the property is being echoed properly, it's not substituted in my JSP. The @version@ token is replaced by {displayVersion} and not it's actual value.

Use Maven Resources Filtering as Aaron suggested and set the delimiters in the Maven Resource Plugin:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>2.5</version>
    <configuration>
      <delimiters>
        <!-- enable maven's standard delimiters -->
        <delimiter>${*}</delimiter>
        <!-- enable your @delimiters@ -->
        <delimiter>@</delimiter>
      </delimiters>
    </configuration>
</plugin>

The Maven resources plugin can replace variables in resources; so if you deliver the JSP (instead of compiling it with the jspc plugin), you can simply let the resource plugin do the work while it copies resources by enabling filtering.
