Michael Osipov commented on MSHARED-1032:
-----------------------------------------
[~bmarwell], you are right. It is indeed called twice for standalone AND Maven
Site Plugin use case in
{{org.apache.maven.reporting.AbstractMavenReport.generate(Sink, SinkFactory,
Locale)}} also both uses cases make sure that {{canGenerateReport()}} is
invoked before {{generate()}} is invoked. This is clearly redudant an can incur
a performance overhead. I will create a new issue and provide a PR.
As for the actual request: There are two spots which are subject to the call, I
think we can add this exception, I have already found a suitable usecase, but
need to check how the system behavior since the signature has changed.

> Project: Maven Shared Components

> 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!
