OK, when I do this I get a cyclic reference and it does not work.
I have:
<project_root>/pom.xml <= this is referred to as my "parent
pom"
and I have a sub-module for logging (has only the
/src/main/resources/log4j.xml
<project_root>/utils/logging/pom.xml
<project_root>/utils/logging/src/main/resources/log4j.xml
In the utils/logging/pom.xml I have this included
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.15</version>
<scope>compile</scope>
</dependency>
so to use in every other project, I put in the top level (parent pom)
this
dependency on
the logging sub-module:
<dependencies>
<dependency>
<groupId>com.acme<groupId>
<artifactId>logging</artifactId>
<version>1.0</version>
<scope>compile</scope>
</dependency>
</dependencies>
and I do not touch any other module anywhere because in every pom
everywhere I have
the following reference to the parent pom:
<parent>
<groupId>com.acme</groupId>
<artifactId>acme.parent-pom</artifactId>
<version>1.0</version>
</parent>
so the parent pom dependency is logging-1.0.jar but the first thing it tries
to compile also has
that dependency.
