Guillaume Nodet updated MNG-7662:
---------------------------------
Description:
The {{SessionScope}} will now create proxies to wrap beans when there's a need
to inject a bean while the session scope is not yet available. Such proxies
require the use of a {{Typed}} annotation, either the
{{org.eclipse.sisu.Typed}} or {{javax.enterprise.inject.Typed}} annotation, to
be put on the bean that requires to be wrapped by a proxy.
{code:java}
@Named
static class MySingletonBean {
@Inject
BeanItf myBean;
}
interface BeanItf {
Session getSession();
}
@SessionScoped
@Typed
static class MySessionScopedBean implements BeanItf {
@Inject
Session session;
public Session getSession() {
return session;
}
}
{code}
=======
Currently DefaultMaven gets the Graphbuilder injected as a strict requirement
at a very early stage. This leads to the problem, that a GraphBuilder
implementation can not use any SessionScoped Components (because the session
scope is not setup yet).
The error then is
{code:java}
1) Error in custom provider, com.google.inject.OutOfScopeException: Cannot
access Key[type=org.apache.maven.execution.MavenSession, annotation=[none]]
