Petr Matousek commented on MWAR-229:
------------------------------------
I have encoutered exactly the same issue as the original submitter. I have
solved it by using <excludes> within the <overlay> but I strongly prefer the
behavior described in the manual. I have also experimented with various order
of an empty <overlay> that has to represent the current project but with no
effect.
> war:inplace overwrite files of current project by those coming from overlay
> war

> Key: MWAR-229
> URL: https://jira.codehaus.org/browse/MWAR-229
> Project: Maven 2.x WAR Plugin
> Issue Type: Bug
> Components: overlay
> Affects Versions: 2.1-beta-1
> Reporter: Julien HENRY
> Attachments: MWAR-229-it.patch
>
>
> I have a web application that depends on another WAR (overlay). According to
> m-war-p documentation [1], when a file is present in both the application and
> the dependent war, the current application is the priority. My understanding
> is that when there are two files with same path
> in both current application and dependent war, this is the file in current
> application that should ultimately be taken to produce the final war.
> Example:
> current application contains the file src/main/webapp/WEB-INF/web.xml
> dependent war contain a nearly empty file dependentWar.war!WEB-INF/web.xml
> When I run mvn war:inplace I can read in the log:
> [INFO] --- maven-war-plugin:2.1-beta-1:inplace (default-cli) @ myWebApp ---
> ...
> [INFO] Processing war project
> [INFO] Processing overlay[ id com.mycompany:dependentWar]
> ...
> [INFO] File[WEB-INF/web.xml] belonged to overlay[currentBuild] so it will be
> overwritten.
> As a result the src/main/webapp/WEB-INF/web.xml file was overwritten in the
> current application by the file coming from the dependent WAR.
> If I run mvn war:exploded the result is correct and the file in
> target/myCurrentWebApp-XX-SNAPSHOT/WEB-INF/web.xml is the one coming from the
> current web app.
