And i need to copy this comment to project B while this transaction. Use Scrip Runner post function: "Adds a comment to linked issues when this issue is transitioned"  and code:
Last Comment:

%>

Its return null.

Hello,

thank you for your answer, but here is also NULL.

You can try like this

<% out << com.atlassian.jira.component.ComponentAccessor.commentManager.getComments(issue).last().body %>
