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

[Rafał Krzewski <Rafal.Krzewski@xxxxxxxxx>]

Now that I changed my project to use war packaging for the modules that 
contribute both webResources and classes to the application, I've run 
into a strange problem:

When I tried running my application I got the follwing error message: 
"Specified working directory does not exist or is not a directory: 
/home/rafal/workspaces/cyklotron-indigo/cyklotron-webapp/target/m2e-webby" 
which is quite correct, because I've blown away the target directory 
more than a few times while tweaking module packaging. I'd expect to 
Webby to re-create this directory behind the scenes and not bail out 
like this. I created the requested directory by hand and tried again. 
This time Jetty was launched but I got an exception in the console:

2011-07-05 19:05:09.696:WARN::Web application not found 
/home/rafal/workspaces/cyklotron-indigo/cyklotron-webapp/target/m2e-webby/war
2011-07-05 19:05:09.697:WARN::Failed startup of context 
o.e.j.w.WebAppContext{/cyklotron,null},/home/rafal/workspaces/cyklotron-indigo/cyklotron-webapp/target/m2e-webby/war
java.io.FileNotFoundException: 
/home/rafal/workspaces/cyklotron-indigo/cyklotron-webapp/target/m2e-webby/war
    at 
org.eclipse.jetty.webapp.WebInfConfiguration.unpack(WebInfConfiguration.java:471)

Which is also correct, because target/m2e-webby/war is missing - it was 
not created & populated by Webby plugin.

Then I've tried to start from scratch - I've deleted the 
'cyklotron-webapp' run configuration. I tried launching again and I got 
the same stacktrace to the console as above.
Then I've restarted eclipse. Same exception.
Then I've tried searching for anything webby related in my workspace 
configuration (cyklotron-webapp/.settings, .metadata/.plugins) but I 
didn't find anything.
Finally I've created a new workspace, imported the web application 
project and tried running it and I got the "Specified working directory 
does not exist..." error message.

Which leaves me very confused, because this morning Webby unpacked my 
application partially into target/m2e-webby/war directory, before 
getting derailed by non-standard overlays...

cheers,
Rafał

Any pointers will be appreciated.
