-------------------------------------------
RedundantThrows rule seems buggy and is removed in recent Checkstyle versions
> Test classpath resolution fails in mvn check:check when
> includeTestSourceDirectory = true

> Key: MCHECKSTYLE-163
> URL: https://jira.codehaus.org/browse/MCHECKSTYLE-163
> Project: Maven Checkstyle Plugin
> Issue Type: Bug
> Affects Versions: 2.6
> Reporter: Chris Whelan
> Assignee: Olivier Lamy
> Fix For: 2.7
>
> Attachments: MCHECKSTYLE-163.zip, resolveTestClasspath.patch

> 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:
> {code:xml}<dependency>
> <groupId>junit</groupId>
> <artifactId>junit</artifactId>
> <version>${junit.version}</version>
> <scope>test</scope>
> </dependency>{code}
> Throw any junit exception within project test code, e.g.:
> {code:java}public class MyCustomTestRunner extends BlockJUnit4ClassRunner {
> public MyCustomTestRunner(final Class<?> klass) throws
> InitializationError {
> {code}
> If RedundantThrows check is enabled, the following error will be thrown:
> {noformat}[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.{noformat}
