Maven - dynamic pom file?

I'm using the Maven plugin was6-maven-plugin to deploy to websphere. When installing an application, there's a configuration value named "updateExisting" that should be false if I am installing a new application, and true if I am updating an existing application. I don't like having to manually toggle this value if I am fresh-installing/updating the application.

The way I see it, I can either add an uninstallApp goal to always uninstall the application before installing it, but this seems a rather silly way to do it.

I've noticed that this plugin also has a goal wsListApps that outputs all applications installed on the server. The output looks like this:

[INFO]   [wsadmin] WASX7209I: Connected to process "server1" on node 1234Node02 using SOAP connector;  The type of process is: UnManagedProcess
[INFO]   [wsadmin] DefaultApplication
[INFO]   [wsadmin] IBMUTC
[INFO]   [wsadmin] MyApplicationEAR
[INFO]   [wsadmin] ivtApp
[INFO]   [wsadmin] query

Is it possible for Maven to scan this output for the string "MyApplicationEAR" and set "updateExisting" to "true" if it is found, and leave it "false" otherwise?

What you need is to be able to update a maven property during the life-cycle, before the phase binded with your was6-maven-plugin. (and using this property as a value for <updateExisting>)

Unfortunately, maven properties are static and cannot be changed at runtime. So at first sight it's impossible to do.

But, there is a plugin : properties-maven-plugin you can use to define new properties at runtime. The value of the property can be defined by a groovy script. Now the question is more about how can you write a groovy script telling if your app is already there or not.

Honestly, I don't know if it's a good idea to use it. I think running the uninstall goal everytime with failOnError set to false is probably the simplest way (and so probably the best, but maybe I am missing something ?)
