[mojo-user] Dynamic substitution of variable inherited from parent pom.xml while executing a shell command using mvn:exec plugin

[Anurag Kumar Nilesh]

Hi,

I have defined a parent pom.xml (as shown below) in which I give values to some 
variables which are accessed in the children pom.xml

<properties>
<PeblVersion>2.0.0</PeblVersion>
 </properties>

Then, in the children pom.xml I have written these lines.
<project>
      <parent>
                     <groupId>yahoo.yinst.tetris</groupId>
                    <artifactId>tetris-pebls-root</artifactId>
                    <version>1.1</version>
                   <relativePath>../root/pom.xml</relativePath>
     </parent>
     ...
    <version>${PeblVersion}</version>
...
            <phase>deploy</phase>
            <goals>
              <goal>exec</goal>
            </goals>
            <configuration>
              <executable>find</executable>
              <commandlineArgs>pkg -name "*.yicf" -exec yinst_create -r -c 
-target_dir target {} ;</commandlineArgs>
            </configuration>
...

So, when I run mvn deploy it finds a .yicf file in pkg folder and tries to 
execute the commands written in it.
The .yicf file contains this line
POMVERSION = `xpath pom.xml //project/version 2>/dev/null | awk -F'[<>]' 
'{print $3}'`

The output I expect is "2.0.0" but instead I am getting "${PeblVersion}" which 
means the value didn't get replaced yet in the children pom.xml.

How can I resolve this issue?
