---------------------------------------

I have got this problem. I used the ant to call checkstyle, then I got the problem:Got an exception - java.lang.RuntimeException: Unable to get class information for @throws tag 'ServletException'.

The cause is that checkstyle can't find out the exception class in classpath. So It only needs to add the jar of the exception class to the classpath. For example:

<checkstyle config="${tools.checkstyle.ruleset}" failOnViolation="false" failureProperty="checkstyle.failure">
<classpath>
	<path refid="classpath.project.lib" />
	<path refid="classpath.tools.libs" />
	<path refid="classpath.catalina" />
</classpath>
<formatter type="xml" tofile="${report.checkstyleReport.xml}" />
<fileset dir="${project.src}" includes="**/*.java" />
</checkstyle>

I add the <path> in classpath, it will run successfully.

> checkstyle reports an error "Unable to get class information" for custom exceptions within the same project.  it is able to load exceptions that are listed as dependencies for the project, but not for other exceptions.  one workaround is to only use throws Exception in the signiture, but that's really a hack.
