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.
