-----------------------------------

[~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.

> Make the BF algorithm as the default option to speed up maven dependency 
> resolution and downloading

> 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.
