a war can't use classes from another war

[Julien Graglia]

Hi,

I have a war named "WarA" with a class a.b.c.Parent.
And another war named "WarB" with a class Child
Child depends on Parent

with Q4Eclipse, the project WarB compile fine.

from console, it fails : mvn clean compile :
[ERROR] BUILD FAILURE
[INFO]
------------------------------------------------------------------------
[INFO] Compilation failure

could not parse error message: [parsing started

import a.b.c.Parent;

(Note : The "clean" phase is important because maven use incremental
compilation and will not try to recompile classes.)

I have already successfully used a war dependancy to add some .css or
.xml. Here I try to use a class from another war.

Here are the poms:

War A :
<project xmlns="http://maven.apache.org/POM/4.0.0";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/maven-v4_0_0.xsd";>
  <modelVersion>4.0.0</modelVersion>
  <groupId>warA</groupId>
  <artifactId>warA</artifactId>
  <packaging>war</packaging>
  <version>1.0-SNAPSHOT</version>
  <name>warA Maven Webapp</name>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.4</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
  <build>
    <finalName>warA</finalName>
  </build>
</project>

War B :
<?xml version="1.0" encoding="UTF-8"?>
<project>
    <modelVersion>4.0.0</modelVersion>
    <groupId>warB</groupId>
    <artifactId>warB</artifactId>

    <name>warB Maven Webapp</name>
    <version>1.0-SNAPSHOT</version>
    <url>http://maven.apache.org</url>
    <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.4</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>warA</groupId>
            <artifactId>warA</artifactId>
            <version>1.0-SNAPSHOT</version>
            <type>war</type>
        </dependency>
    </dependencies>
    <build>
        <finalName>warB</finalName>
    </build>
</project>

Quite simple, no? 
            the "<type>war</type>" in WarB doesn't seems to work..

Do you have an idea?

Thx!
