More details: this debug message appears the first time that something uses the
DefaultRepositoryAssembler from the shared maven-repository-builder component:
http://svn.apache.org/viewvc/maven/shared/tags/maven-repository-builder-1.0-alpha-2/src/main/java/org/apache/maven/shared/repository/DefaultRepositoryAssembler.java?view=markup#l96
http://svn.apache.org/viewvc/maven/shared/tags/maven-repository-builder-1.0-alpha-2/src/main/java/org/apache/maven/shared/repository/DefaultRepositoryAssembler.java?view=markup#l710
The DefaultRepositoryAssembler first looks for the 'project-cache-aware’
ArtifactResolver before falling back to the default - this change was
introduced back in the Maven2 days:
http://svn.apache.org/viewvc?view=revision&revision=564256
but I can’t seem to find out where the 'project-cache-aware’ hinted version of
ArtifactResolver was ever implemented… which is why the first lookup fails and
it goes on to use the default implementation.
Summary: this is a debug log message that is likely unrelated to the actual
issue you’re investigating, it will always happen first time
DefaultRepositoryAssembler is used.
