All modules are always rebuilt when using M2 with a hierarchical structure
--------------------------------------------------------------------------
Key: CONTINUUM-1606
URL: http://jira.codehaus.org/browse/CONTINUUM-1606
Project: Continuum
Issue Type: Bug
Components: Integration - Maven 2
Affects Versions: 1.1
Reporter: Julien S
Priority: Critical
Attachments: continuum.patch
When using Maven2, the recommended directory structure for a multi-module build
is hierarchical, e.g.:
- pom.xml (parent pom of all modules)
--- module1
+-- pom.xml
--- module2
+-- pom.xml
etc
When using such a structure with continuum, if a change is committed in
module28, then EVERY module will be rebuilt: indeed the parent pom will be
rebuilt because the change is "under" its scm tree, and all the other modules
will therefore we rebuilt because of a "dependencies change" on the parent pom.
This can easily multiply the build time by a factor of 10 or 20.
I have attached a patch. It considers that the parent has "changed" only if its
pom.xml has changed. Not sure it is perfect, but it works for me (the patch has
been tested (against continuum-1.1 and trunk). Feel free to rewrite or modify
it as much as you like.
