Re: Can we write a custom webapp plugin that uses the war plugin and its configruation?
Hi Jörg, never thought of that, thanks.

Re: Can we write a custom webapp plugin that uses the war plugin and its configruation?
You might want to take a look at the maven-inherit-plugin: http://www.ops4j.org/projects/pax/construct/maven-inherit-plugin/ -Sven 2009/8/25 Anil-C achalamalase...@gmail.com I am trying to create a new plugin webapp with two goals clean and refresh to extend the functionality of the maven-war-plugin. webapp:clean would clean the webappDirectory and webapp:refresh would refresh the warSourceDirectory and apply modifications to the webappDirectory (similar to war:exploded but doesn't proces the source directory) skipping the web.xml (guessed it right, hotdeploy for jsp's, tags, images alone) and ofcourse use the configuration defined in maven-war-plugin as it is like any filtering, blah blah, without . The way i am hoping to achieve this is,get hold of the maven-war-plugin instance based on the project pom somehow and invoke custom methods with in that Mojo. I don't know if there is a way to do the first part? I have digged through the users forum and the tutorials/blogs available on maven plugin development. However, i couldn't find a good example that i can refer to in my situation. I am not experience plugin writer (infact this is the first onmy own, apart from the standard hello world examples). Any suggesstions that can help me getting through my first plugin is greatly appreciated.

Re: Can we write a custom webapp plugin that uses the war plugin and its configruation?
Thanks for the quick reply. I have tried this plugin earlier thats not what i
wanted. This plugin reads the metadata information of the plugin at compile
time. I need something that can read the configuration of from the pom for
maven-war-plugin (if no configuration specified, take defaults), and provide
them to my custom plugin. To give an example, below is the current
configuration we have in our web application.
pom.xml
...
...
plugins
plugin
groupIdorg.apache.maven.plugins/groupId
artifactIdmaven-war-plugin/artifactId
configuration
warSourceDirectorysrc/webapp/warSourceDirectory
webappDirectory${jboss.expldoed}/webappDirectory
filters
filtersrc/main/filters/${filter}.properties/filter
/filters
webResources
resource
directorysrc/webapp/WEB-INF/directory
filteringtrue/filtering
includes
includetabconfig.xml/include
/includes
/resource
/webResources
/configuration
/plugin
...
...
/pom
When i use my custom goal webapp:refresh - i would like to refresh the
webapp directory alone using the above configuration. I would really not
like to redefined this configuration again for my custom plugin of the pom.
