[maven] branch MNG-6638 updated (542a9f9 -> 9a5569a)
This is an automated email from the ASF dual-hosted git repository.
slachiewicz pushed a change to branch MNG-6638
in repository https://gitbox.apache.org/repos/asf/maven.git.
discard 542a9f9 [MNG-6638] - Prevent reparsing POMs in MavenMetadataSource
add 715d90b Update DOAP Information for new release.
new 9a5569a [MNG-6638] - Prevent reparsing POMs in MavenMetadataSource
This update added new revisions after undoing existing revisions.
That is to say, some revisions that were in the old version of the
branch are not in the new version. This situation occurs
when a user --force pushes a change and generates a repository
containing something like this:
* -- * -- B -- O -- O -- O (542a9f9)
\
N -- N -- N refs/heads/MNG-6638 (9a5569a)
You should already have received notification emails for all of the O
revisions, and so the following emails describe only the N revisions
from the common base, B.
Any revisions marked "omit" are not gone; other references still
refer to them. Any revisions marked "discard" are gone forever.
The 1 revisions listed above as "new" are entirely new to this
repository and will be described in separate emails. The revisions
listed as "add" were already present in the repository and have only
been added to this reference.

[MNG-6638] - Prevent reparsing POMs in MavenMetadataSource
If a dependency on another project is found, don't parse its
POM again, but instead use the model we already have in memory.
This saves a large amount of time and memory for builds that have
lots of subprojects and dependencies between them.
The approach was directly copied from DefaultArtifactDescriptorReader,
which does the same optimization.
