[~Chealer] Has been verified by comparing dependency tree output using DF or
BF with thousands of applications in our company before contributing to Maven
community. So far, no downsides found yet. You may try and report if any issues.

Wow. We tried out the BF changes in our full rebuild pipeline, and the download
set was 2.9GB before with DF and only 900MB with BF! I almost don't believe how
much better it is...
If no regressions are found, BF should be the new default!

Really appreciate to release the BF changes to Maven 3.9.0. This ticket is
created to collect feedbacks about BF algorithm, hoping we could collect more
feedback from Maven users all over the world.

Maven 3.9.0 has been released, with maven-resolver 1.9.4. I tested the
performance boost today, running mvn clean package -DskipTests against
spring-petclinic project. Result as below:Results:Maven 3.8.6time: 15:59
minMaven 3.9.0 + -Daether.dependencyCollector.impl=bftime: 04:35 minI'll try
creating a PR bumping maven-runtime to 3.9.0.{noformat}
I think we should not make some tricky changes in m2e, instead we could share
the feedback to Maven team.
