wei cai updated MRESOLVER-324:
------------------------------
    Description: 
This is a WISH type Jira :D. So far, Maven 3.9.0 has released a BF algorithm which includes changes from below JIRAs along with the DF option (default).
 * MRESOLVER-228
 * MRESOLVER-247
 * MRESOLVER-7

The BF algorithm solves:
 * Cache missing issue when comes to resolve heavy dependencies with different exclusions, it can help speed up dependency resolution especially for large scale enterprise level projects.
 * Improve download speed by:
 ** Skip downloading poms for conflict losers.
 ** Download poms in parallel.

Below is the introduction in [https://maven.apache.org/docs/3.9.0/release-notes.html:]
{noformat}
Choice of resolver collectors: a new BF collector (with parallel POM downloads) has been added along the existing DF one.{noformat}
The solution is already widely adopted at eBay. You can simply enable it by putting below config item into file: ${maven.projectBasedir}/.mvn/maven.config
{code:java}
aether.dependencyCollector.impl=bf {code}
More introduction about this option: [https://maven.apache.org/resolver/configuration.html]

Please try and tells us how much it helps by running:
{code:java}
1. mvn clean install -DskipTests -Dmaven.repo.local=bf -Daether.dependencyCollector.impl=bf 

2. mvn clean install -DskipTests -Dmaven.repo.local=df{code}
With more feedback collected, we would be able to propose the changes to Maven team to make BF as the default.
