Path normalization during inheritance prohibits usage of properties
-------------------------------------------------------------------
Key: MNG-3315
URL: http://jira.codehaus.org/browse/MNG-3315
Project: Maven 2
Issue Type: Bug
Components: Inheritance and Interpolation
Affects Versions: 2.0.8
Reporter: Benjamin Bentmann
Assume a multi-module scenario with the following (non-standard) directory
layout:
project/
project-parent/
project-module-1/
project-module-2/
That is, the parent POM is placed in a sibling directory rather than the parent
directory of the module projects such that the "module path adjustment" is
"../" when inheriting paths/URLs from the project-parent.
Now, consider the following POM snippet for the site distribution (or any other
element where Maven adjusts paths for sub modules):
{code:xml}
<site>
<id>website</id>
<url>dav:http://www.company.org/project</url>
</site>
{code}
All fine so far, but this slightly modified snippet does not work any more:
{code:xml}
<properties>
<site.url>dav:http://www.company.org/project</site.url>
</properties>
...
<site>
<id>website</id>
<url>${site.url}</url>
</site>
{code}
Just replacing the string by a property produces a bad URL for any sub project.
This problems originates from DefaultModelInheritanceAssembler.resolvePath()
that "normalizes" a string like "${site.url}/../project-module-1" to
"project-module-1".
While the usage of the property is not mandatory, I nevertheless think the
moral from this subtle issue should be not to do any path normalization until
all properties have been interpolated, i.e.:
- inheritance ( URL = "${site.url}/../project-module-1" )
- interpolation ( URL =
"dav:http://www.company.org/project/../project-module-1"; )
- path/URL normalization ( URL = "dav:http://www.company.org/project-module-1"; )
Otherwise, Maven calls another weird pitfall its own.
