Laurent Malvert commented on MRESOURCES-160:
--------------------------------------------
Hmmm, I just realized these aren't exactly the same. I followed the goal's
documentation, which then documented the {{<resources>}} by saying to look it
up in the Maven Model documentation, and I ended up there, and somehow got
mixed up between the {{<outputdirectory>}} and {{<directory>}}.
Nonetheless, the NPE seems like a pretty harsh default behavior and should
provide additional information (missing required path).
Sorry for the confusion (would be worth testing if {{<targetPath>}} suffers
from the same issue.

> h2. Context and Issue
> When using the {{maven-resources-plugin}} to copy a resource to a custom
> directory using the {{copy-resources}} goal, it triggers an NPE without any
> additional information when the {{<outputDirectory>}} element is not
> specified:
> {noformat}
> [ERROR] Failed to execute goal
> org.apache.maven.plugins:maven-resources-plugin:2.5:copy-resources
> (copy-resources) on project NPEResourcesBug: Execution copy-resources of goal
> org.apache.maven.plugins:maven-resources-plugin:2.5:copy-resources failed.
> NullPointerException -> [Help 1]
> {noformat}
> However, the documentation at: http://maven.apache.org/pom.html#Resources
> clearly states:
> {quote}
> directory: This element's value defines where the resources are to be found.
> The default directory for a build is ${basedir}/src/main/resources.
> {quote}
> Specifying it explictly with this value works as intended.
> _(Not sure if relevant to maven-resources-plugin or the MSHARED resources
> component?)_
> h2. Test Case
> Or at leat a project to reproduce.
> See the attached project for a working test case, which uses this
> configuration:
> {code}

> <groupId>org.apache.maven.plugins</groupId>
> <artifactId>maven-resources-plugin</artifactId>
> <version>2.5</version>

> <configuration>
> <outputDirectory>
> ${basedir}/resources

> <resource>
> <!--
> works when included explictly set,
> NPE otherwise, though documentation

> "directory: This element's
