Slawomir Jaranowski commented on MRESOLVER-335:
-----------------------------------------------
This is tricky ....
{code:java}
for (Throwable t : result.getExceptions()) {
if (t instanceof ArtifactNotFoundException) {
if (notFound == null || notFound instanceof
ArtifactFilteredOutException) {
notFound = t;
}
if (offline == null && t.getCause() instanceof
RepositoryOfflineException) {
offline = t;
}
} else {
return t;
}
}
{code}
If first exception on the list is not {{ArtifactNotFoundException}} then will
be returned as a cause.
Each exception can be generated by configured repository in user project and
order depends on project/settings
So when we have an exceptions list as
- {{TransferException}}
- {{ArtifactNotFoundException}},
- {{ArtifactNotFoundException}}.
{{TransferException}} will be returned.
Maybe we need check all items on list ... but question is which
{{ArtifactNotFoundException}} should be returned as cause?

> Key: MRESOLVER-335
> URL: https://issues.apache.org/jira/browse/MRESOLVER-335
> Project: Maven Resolver
> Issue Type: Improvement
> Components: Resolver
> Reporter: Slawomir Jaranowski
> Priority: Major
> Fix For: 1.10.0
>
>
> When we have many remote repositories only first
> {{ArtifactNotFoundException}} is returned, all checks for other repositories
> are hidden.
> When we have errors for many artifacts in one request - list of problematic
> artifacts is present in message and only first exception for one artifact.
> Next case is with remote repository filtering, checks for remote repository
> according to filtering also produce {{ArtifactNotFoundException}}, this is
> done at the beginning so exception is first on list.
> In logs and exception we have:
> {code}
> Downloading from my-mirror:
> https://artifactory.../artifactory/remote-repos/org/apache/commons/commons-lang3/4.4.4/commons-lang3-4.4.4.pom
> [WARNING] The POM for org.apache.commons:commons-lang3:jar:4.4.4 is missing,
> no dependency information available
> Downloading from my-mirror:
> https://artifactory.../artifactory/remote-repos/org/apache/commons/commons-lang3/4.4.4/commons-lang3-4.4.4.jar
> [ERROR] Failed to execute goal on project maven-3.9: Could not resolve
> dependencies for project org.test:maven-3.9:jar:1.0.0-SNAPSHOT: Prefix org
> NOT allowed from mayrepo (https://artifactory.../artifactory/myrepo/,
> default, releases+snapshots)
> {code}
> As we see artefact was not found in {{my-mirror}}, but in error report we
> have information about not allowed prefixes - it can be confusing
