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.

>             Project: Maven Resolver
>          Issue Type: Wish
>          Components: Resolver

> 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:
>  * Solve 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 download 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 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 make 
> BF as the default.
