How to Set Assignee to a project role member based on if condition

[Vasiliy Zverev · Accepted solution]

Here you are

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.security.roles.ProjectRoleManager

if(true)
 issue.getAssigneeId( ComponentAccessor.getComponent(ProjectRoleManager.class).getProjectRoleActors().getApplicationUsers().iterator().next().getKey())
