First of all, I think that you're addressing the (what I call) developer way by adding properties for many tings. Even if this would work, it makes the poms difficult to read and understand. I believe future tooling support (like m2eclipse) will solve some of this, but I still regard this as the developer's approach.
For example, I would leave the "generic" scm section out of the corporate pom. Or more correctly, the corporate pom will have a scm section specifying (without the usa of properties) the path to the scm where the corporate pom is located. Then for each product, the parent pom would override this by declaring the correct scm path for it. Have a look at how the corporate pom at Apache, Codehaus, etc is made up. Best-practice that works. It will give you some hints of configuration that you corp parent do lack. /Anders On Thu, Apr 7, 2011 at 12:45, Wolf Geldmacher <[email protected]>wrote: > Hello List. > > I'm aiming at introducing maven (mvn 3.0.3 to be precise) in our > company. > > In preparation for the task I've set up a company wide POM (c-p-p) and a > project specific POM (c-p-p-p) plus a sample project for the developers > here to use as a template (sample-project) - all included below. > > The SCM used is Subversion and the structure of the repositories is > historically grown, which requires me to define a <scm-loc> property > which needs to be reset for every project. > > The problem I'm encountering: > > After "mvn install" for the company and project wide parent POMs I run > "mvn help:effective-pom" from within the sample-project with unexpected > results: > > ... > <groupId>com.company</groupId> > <artifactId>sample-project</artifactId> > <version>2012.0.0-SNAPSHOT</version> > <name>A sample project</name> > <description>A very simple example project.</description> > <url>https://doc.company.com/build/trunk/maven/sample-project</url> > <scm> > <connection>scm:svn: > https://svn.company.com/repos/build/trunk/maven/sample-project/c-p-p-p/sample-project</connection> > <developerConnection>scm:svn: > https://svn.company.com/repos/build/trunk/maven/sample-project/c-p-p-p/sample-project > </developerConnection> > <url>scm:svn: > https://svn.company.com/repos/build/trunk/maven/sample-project/c-p-p-p/sample-project > </url> > </scm> > ... > > -> The project URL that I explicitly (re-)defined in the > sample-project's POM is expanded as I would expect. > -> All URLs in the SCM section of the effective POM have a trailing > "c-p-p-p/sample-project" (as does the project URL if it is inherited > and not explicitly set it in the sample-project's POM). > > I understand that maven does "inheritance before interpolation", so as > the <scm-loc> property is set in the sample-project's POM I would expect > all expansions of the property to have the value defined in the POM. > > What am I missing? > Where does the additional suffixing come from? > Is this a bug? > Is there a way to achieve my goal without having to make it explicit in > every single derived POM? > > As side remarks: The effective POM fpr c-p-p-p looks ok - no unexpected > tailing traces of the parent POM there; and mvn 2.2.1 behaves exactly > the same way. > > Cheers, > Wolf > > > POMs used > > c-p-p/pom.xml: > > <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> > > <!-- Artifact coordinates --> > <groupId>com.company</groupId> > <artifactId>c-p-p</artifactId> > <version>2012.0.0-SNAPSHOT</version> > <packaging>pom</packaging> > > <!-- Artifact description --> > <name>Company Parent POM</name> > <description>Central POM for all of Company.
