If we run mvn install target with this POM file, it will still not build completely as we need to locate dependencies that are not found in the parent POM central repositories (modules and plugins): http://repo1.maven.org/maven2^{Image Removed}

Maven 2 profile files

...

<profile>
<id>profile1</id>
[...]
<activation>
<property>
<name>debug</name>
</property>
</activation>
</profile>

This will activate the profile when the system property "debug" is specified with any value.
         3.3 

<profile>
<id>profile1</id>
...
<activation>
<property>
<name>environment</name>
<value>test</value>
</property>
</activation>
</profile>

This last example will activate the profile when the system property "environment" is specified with the value "test".


h3. (e)	profiles.xml  file for org-glast-groupmanager

Based on the general discussion above of profiles, I  have chosen initially the following profiles.xml file. 

Note: settings.xml file in my Maven2 repository directory (~igor/.m2) is just:

{code:title=settings.xml}
<?xml version="1.0" encoding="UTF-8"?>
<settings>
</settings>

The profiles file will initially point to project specific repositories that are needed to complete the dependency resolution. In the transition period, when some of the files are in Maven 1 repositories (both GLAST and developer ) and only some of the files are in GLAST Maven 2 respository:

http://glast-ground.slac.stanford.edu/maven2/^{Image Removed} or
/nfs/slac/g/glast/ground/maven2

we need to establish the set of repositories to follow the following path in the order of precedence:

1.http://repo1.maven.org/maven2/^{Image Removed}
2. any outside repositories not in maven2 repository above (like apache.org, sun.com, freehep.org)
3.http://glast-ground.slac.stanford.edu/maven2/^{Image Removed}
4.http://glast-ground-slac.stanford.edu/maven1/^{Image Removed}
5. and only than developer specific repositories:
6. ~developer/.m2/repository
7. ~developer/.maven/repository

...

They can be viewed through the web interface

Using ssh at SLAC is nicely described in:
http://glast-ground.slac.stanford.edu/workbook/^{Image Removed} (Under Getting Conntected, Secure Shell).

To learn about ssh and different authentication strategies http://www.linux.com/articles/34958?tid=78&tid=82^{Image Removed}

Basic requirement is that you need to be able to do scp without password authentication.

...

Most of the time there is no configuration for repositories in the pom.xml configuration file
because there is a built-in default repository (pointing to http://repo1.maven.org/maven2^{Image Removed}).
Most of the time, open source projects will publish artifacts to the central repository, but they
can also host their own repositories and not made them available.

To integrate Hibernate into the web application, two different types of dependencies are
required: for the Hibernate code itself, and for the JPA and transactional APIs that are implemented.
The JBoss repository contains both of these types, so configuring the pom.xml configuration
file is easy. A new repositories tag is added under the top-level project tag, which in
turn contains a repository tag with an id tag (providing a unique identifier) and a url tag
(that supplies the URL of the repository).
<project>
...
<repositories>
<repository>
<id>jboss</id>
<url>http://repository.jboss.com/maven2^{Image Removed}</url>
</repository>
</repositories>
<project>

...

mvn install:install-file -DgroupId=<groupId>
-DartifactId=<artifactId> 
-Dversion=<version>
-Dpackaging=jar 
-Dfile=</path/to/downloaded/file>

Note Each Hibernate dependency also has its own dependencies, known as transitive dependencies.
When the project you are using is built for Maven2, the transitive dependencies are configured and downloaded
automatically with the dependency that you have configured. But occasionally, you will encounter
a project that has not been built for Maven2. In this case, you need to add each of the transitive dependencies
individually to the pom.xml configuration file manually.

Guide to using Maven 1.x repositories with Maven 2.x

When you are migrating from Maven 1.x to Maven 2.x you will first be trying to convert your build and to make this easier we have provided a way for you to use your existing Maven 1.x repository so that you don't have to convert your repository before trying to migrate your projects. To use a Maven 1.x repository with your Maven 2.x project you need to specify this in your POM as follows:<project>
...
<repositories>
<repository>
<snapshots>
<enabled>true</enabled>
</snapshots>
<id>my-m1-repository</id>
<name>Maven 1.x Repository</name>
<url>http://repostory.mycompany.com/maven1^{Image Added}</url>
<layout>legacy</layout>
</repository>
</repositories>
...

</project>

Enabling the snapshots is important as Maven 2.x makes a distinction between repositories that contain snapshots and those that don't. In Maven 1.x there is no distinction, so setting snapshots to true will give you the Maven 1.x style repository behavior while using Maven 2.x
