Re: [m2e-users] Dependent projects missing from .war when project is open in Eclipse
Ok I reproduced the bug. For some reason, workspace dependencies of project overlays are not packaged by WTP. It's either a bug in m2e-wtp or upstream WTP. I created  https://issues.sonatype.org/browse/MECLIPSEWTP-245 to follow up on that issue.

So, until this is fixed, that means you need to explicitely add those common project dependencies to your customer project. You can do that in a m2e specific profile : 


 <profile>
      <id>m2e</id>

      <!-- this profile is only activated within eclipse/m2e -->
      <activation>
        <property>
          <name>m2e.version</name>
        </property>
      </activation>
      <dependencies>

        <!-- add project dependencies from overlaid project-->

      </dependencies>
 </profile>

Fred,


thanks for your explanation. You write:

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

I am not sure this is the problem. The classes created by the productioncontrol_server .war project are found just fine (may be that at some point I manually added a dependency to the Eclipse project for those classes but anyway, it works). What is not found are the classes in e.g. the project common_common. But common_common IS a regular .jar project. To me it seems that when common_common is closed or not in the workspace, the .jar from the server is used. But when common_common is open, Eclipse does not use the .jar from the server but the actual project. This compiles fine, but the classes defined in common_common are not added to the exported .war, neither within WEB-INF/classes, nor as a separate .jar file.

Best regards,
Markus

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.

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:
