How to publish SNAPSHOT version

Hi
I have a problem to publish snapshot version, I saw in other tickets comments that `java_export` could publish snapshots but when I'm adding `-SNAPSHOT` to maven coordinates I'm getting following error:
`File name specifies \"snapshot\" for version. Non-unique snapshot versions are not supported. Use unique (timestamped) snapshot versions instead"`

I tired to run publish with `--stamp` option but without success and I'm not able to find anything in rules_jvm_external sources.
Could you give me a hint?
thanks

Start by reading the java_export documentation and inspecting the rules_jvm_external sources for Maven coordinate handling and the --stamp option. The issue is resolved when the supported way to publish a timestamped SNAPSHOT, or the reason it is unsupported, is documented and verified.
