Re: [m2e-users] Dependent projects missing from .war when project is ope

[Fred Bricon <fbricon@xxxxxxxxx>]

m2e doesn't support workspace projects generating more than one artifact (see 
http://dev.eclipse.org/mhonarc/lists/m2e-users/msg02514.html )

More specifically, your war project declaring <archiveClasses>true doesn't produce a jar with  <classifier>classes</classifier> inside the workspace. In the future, we *may* be able to generate that extra jar at deployment time in m2e-wtp, but we're not there yet.

In your case, your best chance is to move those classes to an actual jar module.

Fred Bricon

Hi again,

what can I do to increase the probability that my question below is answered? The problem I described is real and can be reproduced always with the setup I describe below. I read a lot on forums and tried googling for problems like this but did not find any hints as to what I can try to fix or work around the problem.

Hi everyone,

I have the problem that dependent projects are not included in the JAR deployed to Tomcat 6 when the dependent project is open.

My project has the following structure:

customer-project depends on
  productioncontrol_server depends on
     common_common and
     common_database and
     common_geometry and
     ... some other projects and ...
     ... libraries ...

You find below the pom.xml files of the "customer-project", the "productioncontrol_server" and "common_common".

When I have a workspace with, say, "customer-project" and "productioncontrol_server" open and all other projects closed, the "customer-project" is built successfully and can be deployed to the Eclipse-internal Tomcat 6 without problems. The dependent projects like "common_common", "common_database" etc. are added to the "productioncontrol_server" project as individual .jar file and then deployed using the overlay.

However, when I open a dependent project like "common_common", the project "common_common" is added as a dependency to the "productioncontrol_server" project in Eclipse settings (which is good) and the "common-....jar" file disappears from the .war file deployed to the eclipse-internal Tomcat 6 server (which is bad). I can check this when using Export->Jar File in Eclipse that the file "common-...jar" is not there anymore in the .war as soon as I open the project.

My environment:

Eclipse Indigo Release Build ID 20110615-0604
Eclipse EGit
m2e 1.0.100.20110804-1717
Maven Integration for WTP 0.14.0.20110928-2045

These are my pom.xml files:
