Upgraded to 8.18.2 and we have a bunch of scriptrunner scripts broken due to ComponentManager

[Jeremiah Cargill]

How do I convert the Script that was working below?

import com.atlassian.jira.issue.Issue;
import com.atlassian.jira.ComponentManager;
import com.atlassian.jira.issue.CustomFieldManager;
import com.atlassian.jira.issue.fields.CustomField;
import com.atlassian.jira.component.ComponentAccessor;
import org.apache.commons.lang.time.DateUtils;
import java.text.SimpleDateFormat;
import java.util.Date.*;

if (issue.isSubTask()){

SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/YYY");

def cf = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Launch Date Site")
if (cf) {
def result = issue.parentObject.getCustomFieldValue(cf);
if (result){
return sdf.format(result);
} else {
return
}
}
return
}

return
