I have a web application which is structured in this way:
A.jar -> B.war -> C.war
I'm using Eclipse Juno and the WTP version is 1.1. The A.jar is a workspace utility project which is being included by B.war. B.war is a war project that is included by C.war as an overlay. That's the way I'm doing that:
<dependency>
<groupId>com.projects</groupId>
<artifactId>B</artifactId>
<version>1.0-SNAPSHOT</version>
<type>war</type>
<scope>runtime</scope>
</dependency>
After that, I deploy the C project to the Tomcat server. That works like a charm if I manually deploy the Maven generated war to the Tomcat, because A.jar is included in WEB-INF/lib. However my problem comes when I let m2e-wtp do the deploy, because it's doing the overlay properly but not including the A transitive dependency. I tried including it as a pom, as I read somewhere around here, but I have the same result.
<dependency>
<groupId>com.projects</groupId>
<artifactId>B</artifactId>
<version>1.0-SNAPSHOT</version>
<type>war</type>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>com.projects</groupId>
<artifactId>B</artifactId>
<version>1.0-SNAPSHOT</version>
<type>pom</type>
</dependency>
I'm using the newest versions of m2e (1.2) and m2e-wtp (0.16) and have my projects updated with the Maven configuration.
Is it an m2e-wtp issue or simply do I have to organize my project in other way?
EDITED
I noticed m2e-wtp configuration is stored into Eclipse's project./settings/org.eclipse.wst.common.component file. That's how it looks for my war:
<dependent-module deploy-path="/"
handle="module:/overlay/prj/B?includes=**/**&excludes=META-INF/MANIFEST.MF">
<dependency-type>consumes</dependency-type>
</dependent-module>
<dependent-module deploy-path="/"
handle="module:/overlay/slf/?includes=**/**&excludes=META-INF/MANIFEST.MF">
<dependency-type>consumes</dependency-type>
</dependent-module>
As I can see the war dependency is set for consume while the jar dependencies are set for use.
Released m2e-wtp version 0.17 doesn't seem to fix it.
EDITED (2013-08-30)
Today I was back to the same problem. Even I have Eclipse kepler installed with the latest stable release of WTP out of the box, this problem seems to persist. I thought it was solved, but I apparently mischeck it...
I also have this problem. I have an ugly workaround:
Put all the original war's dependencies in a separate project (type jar) and make both original war and overlay war depend on that. So for the example:
A.jar -> B.war -> C.war
becomes
A.jar -> B-dependencies.jar (new module called B-dependencies created)
B-dependencies.jar -> B.war
B-dependencies.jar -> C.war
Note that it's not specific to Tomcat; I'm using JBoss.
I think it is not a problem of your project organization. Your issue is very similar to this m2e-wtp bug report.
It seems to be a Eclipse Juno and WTP Plugin problem.
I had the same problem and i solved in this way:
Hope this helps.
