> Hi everyone,
> the [{{AbstractReportMojo}} in
> reporting-impl|https://maven.apache.org/shared/maven-reporting-impl/apidocs/org/apache/maven/reporting/AbstractMavenReport.html]
> implements a method [{{canGenerateReport()}} from
> reporting-api|https://maven.apache.org/shared/maven-reporting-api/apidocs/org/apache/maven/reporting/MavenReport.html].
> 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 {{canGenerateReport()}}
> * Removing the declared {{IOException}} in PlexusUtils ([PR
> exists|https://github.com/codehaus-plexus/plexus-utils/issues/180]) and
> Maven-Utils (issue: tbd).
> Thanks!
