Property inheritance

[Alastair Rodgers <al...@phocis.com>]

Hello, 

I've just started using Maven over the last couple of days, and I must say, my first impressions are very positive (I'm used to dealing with lots of nearly-identical Ant scripts!). Thanks. 

I've been trying to use property inheritance, and I gathered from the mailing list archive that project.properties & build.properties aren't inherited. I tried to get round this by creating a global.properties file and manually loading the properties from it in my base maven.xml: 

  <jelly-core:set var="project.root" value="${pom.parentBasedir().getParentFile().getCanonicalFile()}"/>
  <jelly-util:properties file="${project.root}/etc/global.properties"/>

In global.properties I have: 

  maven.repo.local=/usr/local/data/maven/repository

I then have a sub-project which inherits from this base. If I run, say "maven jar" on the sub-project and dump the value of maven.repo.local to the console from the sub-project's maven.xml, I find it has the desired value (from global.properties). However, Maven is still actually using the default repository (/home/<user>/.maven/repository to do the build) - e.g. if I delete this dir, Maven creates it and starts downloading all the jars again. 

Is there a way round this problem? 

Thanks, 
Al.

I've found it easier to simply add in a common bin directory, a modified 
copy of the maven script with the added properties.

set a global
export MAVEN_HOME_LOCAL=/mavenrepository
or some such place.  Put that in your /etc/profile so everybody shares it.
