             Summary: API change: let `canGenerateReport` throw an Exception
                 Key: MNG-7393
                 URL: https://issues.apache.org/jira/browse/MNG-7393
             Project: Maven
          Issue Type: Improvement
            Reporter: Benjamin Marwell


Hi everyone,

the `AbstractReportMojo` declares a method `canGenerateReport`.

However, it is unable to throw any exceptions. Not even MojoExecutionEx or MavenReportEx, which is most unfortunate.

It is being used twice:

Once in execute() throws MojoExEx

and in

generate() throws MavenReportEx (and is called by execute()).

This way, there is no way for reporting plugins to scan for files, because FileUtils::getFiles DOES throw a IOException, which then cannot be wrapped. However, the IOException from that method is useless anyway, because it is never declared in any methods it calls.

Therefore please consider:
 * Declaring any Exception on `canGenerateReports`
 * Removing the declared IOException in PlexusUtils ([PR exists|https://github.com/codehaus-plexus/plexus-utils/issues/180]) and Maven-Utils (issue: tbd).

Thanks!
