Abel Salgado Romero commented on MSITE-849:
-------------------------------------------
Adding {{SessionScoped}} causes the following error and component not even
starts.
{code:java}
com.google.inject.ProvisionException: Unable to provision, see the following
errors:
1) Error in custom provider, com.google.inject.OutOfScopeException: Cannot
access Key[type=org.asciidoctor.maven.site.AsciidoctorDoxiaParser,
annotation=[none]] outside of a scoping block
at org.asciidoctor.maven.site.AsciidoctorDoxiaParser.class(Unknown Source)
while locating org.asciidoctor.maven.site.AsciidoctorDoxiaParser
at ClassRealm[plugin>org.apache.maven.plugins:maven-site-plugin:3.8.2,
parent: sun.misc.Launcher$AppClassLoader@18b4aac2] (via modules:
org.eclipse.sisu.wire.WireModule -> org.eclipse.sisu.plexus.PlexusBindingModule)
while locating org.apache.maven.doxia.parser.Parser annotated with
@com.google.inject.name.Named(value=asciidoc)
{code}
And injecting {{MavenSession}} has the same effect as the {{MavenProject}}.
Checking the whole stacktrace I realize that during {{site:run}}, the Doxia
component runs inside a web context. And the call stack is completely different
from the one when building with {{site:site}} (see attachment below), there's
no Mojo involved. That makes me think that no Maven context is created and that
the error does in fact make a lot of sense. I can see how the web context is
created...

> Unable to inject MavenProject when using `mvn site:run`

> Key: MSITE-849
> URL: https://issues.apache.org/jira/browse/MSITE-849
> Project: Maven Site Plugin
> Issue Type: New Feature
> Affects Versions: 3.7.1, 3.8.2
> Reporter: Abel Salgado Romero
> Assignee: Michael Osipov
> Priority: Major
> Attachments: site_site.png
>
>
> In https://github.com/asciidoctor/asciidoctor-maven-plugin we inject a
> MavenProject to obtain addition configurations from the pom.xml
> (https://github.com/asciidoctor/asciidoctor-maven-plugin/blob/a4d86a949643ab68c124fd4c1b9b936412637d93/src/main/java/org/asciidoctor/maven/site/AsciidoctorDoxiaParser.java#L54).
> This works fine with {{site:site}}, but when using {{site:run}} and accessing
> one of the Asciidoc generated pages we get the error below.
> I saw that:
> * The error occurs when trying to retrieve the instance of the MavenProject.
> * Behavior is the same if I directly inject the MavenProject instead of using
> a provider. That is, {{site:site}} works, {{site:run}} fails because it
> cannot find the instance.
