Steve Cohen created MASSEMBLY-671:
-------------------------------------
Summary: Cryptic debug warning message needs improvement and/or
documentation
Key: MASSEMBLY-671
URL: https://jira.codehaus.org/browse/MASSEMBLY-671
Project: Maven Assembly Plugin
Issue Type: Bug
Components: component descriptor
Affects Versions: 2.4, 2.2.1
Environment: irrelevant
Reporter: Steve Cohen
I have used the assembly plugin both versions 2.4 and 2.2.1. While the plugin
basically works, I have some problems with it, (see MASSEMBLY-670), which I
suspect may be related to the following message that shows up when running
Maven in debug mode (-X):
{noformat}
[DEBUG] All known ContainerDescriptorHandler components: [plexus,
metaInf-spring, metaInf-services, file-aggregator]

This message is singlularly unhelpful. Evidently there is something that the
plugin doesn't like about my deployment descriptor, but this message tells me
nothing that would help me get to the bottom of what that is. And despite this
message, the plugin goes on to give me essentially what I want for an assembly
(with the exception of the problem in MASSEMBLY-670).
Users should have better help here in creating assembly descriptors.
Regardless of what is "wrong" (what unwritten law was violated) with my
assembly descriptor, a more informative error message or at least documentation
should be available.
I am not alone, here. Google "Cannot find ArtifactResolver with hint:
project-cache-aware" and many hits will be found.
