scoverage:report cannot run with --offline flag

[zzgzy]

I am using mvn -U dependency:resolve-plugins dependency:go-offline install to pre-download everything and when running mvn --offline scoverage:report, I got the POM for org.scoverage:scalac-scoverage-plugin_2.10:jar:1.3.0 is missing, no dependency information available error.

The POM:

The problem is that It will only download the .jar but not .pom files for me. In the folder, I could only see scalac-scoverage-plugin_2.10-1.3.0.jar and scalac-scoverage-plugin_2.10-1.3.0.jar.sha1 but no pom file. Could anyone help and provide some insights on it? Thank you in advance!

@zzgzy the plugin adds some artifacts dynamically during execution, so only getting dependencies while online won't work. What you can do is execute it once when online and then go offline. I think it should help. Lmk if not.

Please reopen if you think we can do better here.
