Re: [m2e-users] webby: Could not locate configuration for maven-war-plug

[Rafał Krzewski <Rafal.Krzewski@xxxxxxxxx>]

I've switched my projects to war packaging with attached jars and now I'm getting the following two errors for each project:

Utility Module and Dynamic Web Module 2.5 cannot both be selected.
One or more constraints have not been satisfied.

This makes sense, as much as I understand how WTP works. It seems that to get around this, I would need to get rid of the attached jars and package the classes in WEB-INF/classes. Then again I need those classes as compile time dependencies for other modules, and while I suspect it might work under Eclipse/WTP, putting a war on compile classpath under standalone Maven probable would not work...

My previous setup using jars with attached wars was admittedly a bit convoluted, but war overlays contributing both classes and webResources seems pretty much standard usage. Am I missing something here?

cheers,
Rafał

Hi,

I've just tried running a web application with webby 0.1.0.201106240305 and it failed to start with message "Could not locate configuration for maven-war-plugin".

Here's POM for the war project I was trying to launch: http://objectledge.org/fisheye/browse/cyklotron/trunk/cyklotron-webapp/pom.xml?hb=true#to105

As you can see maven-war-plugin configuration definitely is in there :). I looked at the target directory and I've noticed that m2e-webby directory was created and some of the application contents were unpacked into it. Judging from what has been unpacked and what hasn't I'm guessing that overlays coming from projects that have war packaging were processed correctly. There are however overlays coming from wars generated as attached artifacts. See http://objectledge.org/fisheye/browse/cyklotron/trunk/cyklotron-ui/pom.xml?r=9827#to77 and http://objectledge.org/fisheye/browse/ledge/trunk/ledge-maven-assemblies/src/main/resources/assemblies/content-war.xml?hb=true. This works with standalone maven build. I haven't checked yet if current m2e-wtp can handle it. 0.12.x and lower definitely could not. I don't know if it's supposed to be in webby. Even if not, more informative error message would be nice.

As I think about it, I could flip things over and change the packaging of these non-standard projects to war and generate jars with classes as attached artifacts instead. War plugin has a configuration option for this if I remember correctly. That would actually make things less complicated. I'll try that and let you know if it fixes webby problem I've run into.

cheers,
Rafał
