Unable to run clean command because plugin was not found.

[rhuanpacto]

I ran the command
docker run -it --rm --name my-project -v "$PWD":/data andreptb/maven:3.2.5-jdk6 mvn clean

Plugin org.apache.maven.plugins:maven-clean-plugin:2.5 or one of its dependencies 
could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:
maven-clean-plugin:jar:2.5: Could not transfer artifact org.apache.maven.plugins:
maven-clean-plugin:pom:2.5 from/to central (https://repo.maven.apache.org/maven2):
Received fatal alert: protocol_version -> [Help 1]

What's the problem?

@rhuanpacto ,

I was able to reproduce the problem now. It seems the current SSL version used in maven central repo (TLS 1.2) is not supported by jdk 1.6, hence the failure fetching any dependencies from there.

You don't need to use maven with jdk 1.6 to build your projects. You can use a newer jdk/maven but configure to be compatible with source code for java 6. Check maven-compiler-plugin documentation.

I'm affraid there's nothing more we can do regarding this issue.
