Quote from the dependency plugin documentation:

{quote}
By default, maven-dependency-analyzer is used to perform the analysis, with limitations due to the fact that it works at bytecode level, but any analyzer can be plugged in through analyzer parameter.
{quote}

If you only use constants from {{org.apache.avalon.excalibur.pool.Recyclable}} or if you only extend it, you'll face this limitation. You can use a different analyzer or you can use the parameter {{ignoredUnusedDeclaredDependencies}}:

||Name||Type||Since||Description||
|ignoredUnusedDeclaredDependencies|String[]|2.10|List of dependencies that will be ignored if they are declared but unused. The filter syntax is:
{noformat}[groupId]:[artifactId]:[type]:[version]{noformat}
where each pattern segment is optional and supports full and partial * wildcards. An empty pattern segment is treated as an implicit wildcard. *
For example, org.apache.* will match all artifacts whose group id starts with org.apache., and :::*-SNAPSHOT will match all snapshot artifacts.|

>                 URL: https://issues.apache.org/jira/browse/MDEP-156
>             Project: Maven Dependency Plugin
>          Issue Type: Bug
>          Components: analyze
>    Affects Versions: 2.0
>            Reporter: Elliot Metsger
>
> When executing dependency:analyze on my project, analyze mistakenly identifies a compile time dependency as unused. 
> When I remove the dependency from the POM, the compile fails.  When I add it back in the compile succeeds.
> The POM in question is located at: 
> http://dspace.svn.sourceforge.net/svnroot/dspace/branches/dspace-1_5_x/dspace-xmlui/dspace-xmlui-wing/pom.xml
> The artifact that is mistakenly identified as "declared but unused" is:
> {code:xml}<dependency>
>        <groupId>org.dspace.xmlui.excalibur</groupId>
>        <artifactId>excalibur-pool-api</artifactId>
>        <version>2.1</version>
>  </dependency>{code}
> The compile fails like so:
> /Users/esm/idea/workspace/dspace-1.5.x/dspace-xmlui/dspace-xmlui-wing/src/main/java/org/dspace/app/xmlui/wing/AbstractWingTransformer.java:[68,16] cannot access org.apache.avalon.excalibur.pool.Recyclable
> file org/apache/avalon/excalibur/pool/Recyclable.class not found
> public abstract class AbstractWingTransformer extends AbstractTransformer
> org.apache.avalon.excalibur.pool.Recyclable is an interface implemented by org.dspace.app.xmlui.wing.BitstreamReader and org.dspace.app.xmlui.cocoon.DSpaceFeedGenerator.
