A Maven plugin used by the Tuscany SCA project for OSGi JUnit testing. There's some discusssion about it at:
http://apache.markmail.org/message/uxt7afrquwc75qxj

The Tuscany OSGi Junit plugin is derived from maven-surefire-plugin to add the OSGi support. It takes the same set of configurations as maven-surefire-plugin. Here is what it does:

1) Generate two bundles for the main and test classes respectively. The test bundle is a fragment of the main bundle.

For example, the plugin generates the following bundles for sample-calculator-osgi.jar:
* sample-calculator-osgi-osgi.jar
* sample-calculator-osgi-osgi-tests.jar

2) Find the EquinoxHost class from tuscany-node-launcher-equinox and create an instance
3) Start the equinox runtime
4) Set up the classloader for surefire so that it uses OSGi classloading for the test cases with the test bundle.
5) Delegate to surefire to run the unit tests

Future improvement:
As now we use the OSGi framework launch APIs to start an OSGi runtime, it should be ideal to allow either Equinox 
or Apache Felix as the runtime. The only difference would be a list of properties and we can make them configurable 
for the plugin to take a property file.

To build, from the top maven-osgi-junit-plugin run maven:

mvn

or once all the dependencies have been downloaded and a succesful build run use:

mvn clean install -o

So as to avoid the Tuscany SCA project using SNAPSHOT dependencies any changes
to this module should be released and the Tuscany SCA project updated to use 
the newly released version.

To release this module:

mvn release:prepare

followed by: 

mvn release:perform

That will automatically create an SVN tag from the release, update the version 
numbers in the pom.xml files in the trunk and tag, and deploy the artifacts to the
staging repository defined by the <deploy.altRepository> in your Maven settings.xml.
While running it will prompt you for the names for the tag, release version etc.

In your maven settings.xml file you must have a server defined named "apache.releases",
and a profile named "release". For example:

  <servers>
    ...
    <server>
      <id>apache.releases</id>
      <username>antelder</username>
      <privateKey>\ant\id_dsa</privateKey>
      <passphrase>xxx</passphrase>
      <directoryPermissions>775</directoryPermissions>
      <filePermissions>664</filePermissions>
    </server>
  </servers>

  <profiles>
    ...
    <profile>
      <id>release</id>
      <properties>
        <gpg.passphrase>...</gpg.passphrase>
        <deploy.altRepository>apache.releases::default::scp://people.apache.org/home/antelder/public_html/tuscany/maven-osgi-junit-plugin-1.0</deploy.altRepository>
      </properties>
    </profile>
  </profiles>

Call a vote to release the module, eg: http://apache.markmail.org/message/6jnlfxbx7uklt5nv

After a successful vote copy the staging artifacts to the live repository, eg: 

cp -p -v -R  maven-osgi-junit-plugin-1.0/org/apache/tuscany/maven/plugins/ /x1/www/people.apache.org/repo/m2-ibiblio-rsync-repository/org/apache/tuscany/maven/plugins
