[jira] Commented: (MWAR-218) Missed XSD Schema for the file webapp-cache.xml

["Stephane Nicoll (JIRA)" <ji...@codehaus.org>]

Stephane Nicoll commented on MWAR-218:
--------------------------------------

Not sure I understand what you mean with warnings. This file is purely internal to the plugin and is not packaged in any way in your final artifact.

Validation here would be necessary if a 3rd party was creating this file. But this just won't happen the way the plugin is designed today.

>                 URL: http://jira.codehaus.org/browse/MWAR-218
>             Project: Maven 2.x WAR Plugin
>          Issue Type: Improvement
>    Affects Versions: 2.1-beta-1
>            Reporter: Felipe Gaúcho

> When packaging a web-application, maven-war-plugin generates a cache file, as described here: http://maven.apache.org/plugins/maven-war-plugin/exploded-mojo.html#cacheFile
> This cache file is an XML file but the generated file doesn't contains an Schema or DTD declaration on its header. This makes impossible to validate such file, generating warnings in the most common Java IDEs. Since it is a mandatory XML file I believe it should has a model specification somewhere (a XSD Schema I hope), eventually just not released for public usage.
> The steps I expect to make Maven 2 WAR plugin better:
> - to modify the generator of the webapp-cache.xml file to include the proper XML header (with namespace and schema location)
> - to make the schema of such file publicly available, in order to give the developers and automatic tools a chance to validate any error in a deployable artifact.
> This will give us a chance to detect potential bugs before to deploy a web-application.
> ----------- The expected header is something like:
> <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
> <webapp-structure xmlns="http://maven.apache.org/plugins/maven-war-plugin" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
> 	xsi:schemaLocation="http://maven.apache.org/plugins/maven-war-plugin
> http://maven.apache.org/???/???.xsd">
> ...
> </webapp-structure>
