Parent Dependencies
Hi All
We have a project with multi-level modules.
Main ---- core------dao
+---business
>From what I've read, if I've defined the dependency in the Main
module, I don't need to repeat the defintion the dao module. Is this
correct, because it doesn't seem to work for me?
Regards
Kiren

Sure, the inheritance is transitive. You can have as many levels as you
want:
If you have a hierarchy like this:
* A
o B
+ C
All dependencies declared in A will also be available for B and C and
all dependencies declared in B will also be available for C.

Thanks for the explanation Guillame...this works as you've stated.
However my question is, is the inheritance transitive, i.e, the child
pom would inherit the dependencies of the "grandparent" pom? From what
I'm seeing this is not the case.

I am not sure I understood you correctly but here is what I can tell:
Let's say you have a Main project which contains two modules: dao and
business:
* Main
o dao
o business
If in your Main pom.xml, you have defined the following:
<groupId>a.b.c</groupId>
<artifactId>Main</artifactId>
<version>1.0<version>
<dependencies>
<dependency>
<groupId>x.y.z</groupId>
<artifactId>azerty</artifactId>
<version>1.0</version>
</dependency>
<dependencies>
If in your dao pom.xml, you have defined the following
<parent>
<groupId>a.b.c</groupId>
<artifactId>Main</artifactId>
<version>1.0<version>
</parent>
then yes, you should inherit the dependency provided in you Main
pom.xml, ie, in my example:
<groupId>x.y.z</groupId>
<artifactId>azerty</artifactId>
<version>1.0</version>
Without any more information, it will be hard to help more I think.
Cheers,
Guillaume
