Description

We do still experience this "supposed to be fixed" Bug in maven resolver in our team. We use maven 3.8.2 and I guess it is packaged with 1.6.3 resolver. It occurs sometimes and never with

-Daether.metadataResolver.threads=1 

 

Apache Maven 3.8.2 (ea98e05a04480131370aa0c110b8c54cf726c06f)
Maven home: /usr/local/Cellar/maven/3.8.2/libexec
Java version: 1.8.0_301, vendor: Oracle Corporation, runtime: /Library/Java/JavaVirtualMachines/jdk1.8.0_301.jdk/Contents/Home/jre
Default locale: en_GB, platform encoding: UTF-8
OS name: "mac os x", version: "10.16", arch: "x86_64", family: "mac" 

 

This is how the maven run with

mvn -X install 

fails
