Description

After successfully creating an archetype from a project (using archetype:create-from-project), a NullPointerException is encountered when executing the "integration-test" goal of the archetype plugin. The steps to reproduce are:

cd /tmp
svn co https://squirrel-sql.svn.sourceforge.net/svnroot/squirrel-sql/trunk/sql12/plugins/example example
cd example
mvn -X clean install > build.log
mvn -X archetype:create-from-project > archetype-create.log
cd /tmp/example/target/generated-sources/archetype
mvn -X -e archetype:integration-test > archetype-test.log

The NullPointerException is listed at the bottom of /tmp/example/target/generated-sources/archetype/archetype-test.log and appears as follows:

Caused by: java.lang.NullPointerException

        at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:107)

The attached zip file contains all of the logs that were generated. The source is available on the web with the svn checkout listed above for convenience.
