StringIndexOutOfBoundsException when generating archetype for multi-module
project
----------------------------------------------------------------------------------
Key: ARCHETYPE-329
URL: http://jira.codehaus.org/browse/ARCHETYPE-329
Project: Maven Archetype
Issue Type: Bug
Components: Archetypes
Affects Versions: 2.0-alpha-5
Reporter: Petter Måhlén
Given an archetype setup with the following multi-module archetype resources
structure:
ROOT - pom.xml
- container-test - pom.xml (this should be a sub-module in the resulting
project)
- container (a directory)
The archetype:generate goal fails in the getOutputFile method, with the
following exception:
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal
org.apache.maven.plugins:maven-archetype-plugin:2.0-alpha-5:generate

The CreateProjectFromArchetypeMojo hides the stack trace of the underlying
exception (this should be fixed, too, I think), but by adding debug information
to the mojo in a couple of places, and enabling debug logging, I was able to
get the following trace:

The cause of the problem seems to be that the directory name ('container') is a
substring of the moduleOffset parameter, which eventually causes the following
call to be illegal:
+ templateName.substring( moduleOffset.length() );
I would have included a fix, but I don't understand what this code is doing, so
I can't really do that. Hopefully this should be enough information to solve
the problem, though. Also, it would be great to give some better error
reporting by not catching Exception and swallowing it, I think.
