Brett Porter updated MNG-3146:
------------------------------
Fix Version/s: 2.0.x
> POM properties overriden by POM of dependend artifact
> -----------------------------------------------------
>
> Key: MNG-3146
> URL: http://jira.codehaus.org/browse/MNG-3146
> Project: Maven 2
> Issue Type: Bug
> Affects Versions: 2.0.6
> Reporter: Jörg Hohwiller
> Fix For: 2.0.x
>
>
> In my project I use properties (in pom.xml: properties tag, profiles,
> filters) to avoid redundancies (e.g. versions of artifacts used in various
> modules) or to make decisions that depended on the environment (e.g. platform
> specific artifacts). This worked fine for me and I was happy until now,
> because I found a bug in maven:
> If an artifact is referenced as dependency that defines the same property, it
> overwrites the property. This behavior is IMHO inacceptable.
> To avoid missunderstandings I try to say the same again with other words as
> example:
> I have my root pom.xml that says:
> <properties>
> <org.apache.commons.dbcp.version>1.2.1</org.apache.commons.dbcp.version>
> </properties>
> Now one of my modules that inherits from this pom says:
> <dependency>
> <groupId>commons-dbcp</groupId>
> <artifactId>commons-dbcp</artifactId>
> <version>${org.apache.commons.dbcp.version}</version>
> </dependency>
> So far it works fine. But If I also have a dependency on "foo" in the same
> module
> and the POM of foo says
> <properties>
> <org.apache.commons.dbcp.version>1.1</org.apache.commons.dbcp.version>
> </properties>
> Then my project ends up with commons-dbcp version 1.1.
> I can even add an exclusions tag to the foo dependency that excludes
> commons-dbcp without help
> because I do not inherit the dependency on commons-dbcp from foo but foo
> overrides my property.
> I hope my information is good enough to understand my problem.
> I would expect that the pom of a dependency does NOT influence the
> environment of my pom at all!
