Atlassian-public failed: SSL peer shut down incorrectly

Hi! After all steps from https://developer.atlassian.com/server/framework/atlassian-sdk/create-a-helloworld-plugin-project/ I have this error (last command was “atlas-run”):

https://maven.atlassian.com/repository/public is available from browser.
Windows 10, firewall is turned off.

  1. How to fix this?
  2. Why com.atlassian.sal, com.atlassian.plugin are not found in MyPluginComponentImpl
    using latest Intellij Idea? After “mvn install”:
([ERROR]     Unresolveable build extension: Plugin com.atlassian.maven.plugins:maven-jira-plugin:6.3.21 or one of its dependencies could not be resolved: Failure to find com.atlassian.maven.plugins:maven-jira-plugin:jar:6.3.21 in https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced -> [Help 2]
