>             Project: Maven 2.x Checkstyle Plugin
>          Issue Type: Bug
>    Affects Versions: 2.7
>            Reporter: Chris Whelan

> When includeTestSourceDirectory=true is set for maven-checkstyle-plugin, the full test
classpath should be made available to checkstyle.  Patch included to resolve issue by setting
@requiresDependencyResolution to test.
> In DefaultCheckstyleExecutor.java the checker.setClassLoader() is configured using the
classpath string from request.getProject().getTestClasspathElements() (see DefaultCheckstyleExecutor
line 114).
> However, the CheckstyleViolationCheckMojo only has @requiresDependencyResolution compile
which means that pom dependencies which have been declared as <scope>test</scope>
are not returned by project.getTestClasspathElements().
> This is a particular issue for the checkstyle RedundantThrows check (http://checkstyle.sourceforge.net/config_coding.html#RedundantThrows)
as it requires all Exceptions to be available on it's classpath.
> If code throws an Exception which has been imported from a maven <scope>test</scope>
dependency, the exception will not be available on the classpath and this checkstyle check
will fail.
> Example:
> Include junit as a test scope dependency in the project POM:
> <dependency>
>   <groupId>junit</groupId>
>   <artifactId>junit</artifactId>
>   <version>${junit.version}</version>
>   <scope>test</scope>
> </dependency>
> Throw any junit exception within project test code, e.g.:
> public class MyCustomTestRunner extends BlockJUnit4ClassRunner {
> 	public MyCustomTestRunner(final Class<?> klass) throws InitializationError {
> If RedundantThrows check is enabled, the following error will be thrown:
> [INFO] --- maven-checkstyle-plugin:2.7-SNAPSHOT:check (checkstyle-verify) @ sample-project
---
> [INFO] Starting audit...
> C:\Working\hg\sample-project\src\test\java\com\sample\support\junit\MyCustomTestRunner.java:28:72:
warning: Unable to get class information for InitializationError.
> Audit done.
> [ERROR] MyCustomTestRunner.java[28:72] Unable to get class information for InitializationError.
