我正在尝试使用此耙子从 Gmail IMAP 服务器接收电子邮件并在 OpenProject 中创建任务。我已经设置了一个执行这个 rake 的 cron 作业：
rake redmine:email:receive_imap \
host="imap.gmail.com" \
username="username@gmail.com" \
password="pwd" \
ssl=true \
port=992 \
project="bugtest" \
tracker="bug" \
folder="INBOX"
执行后，我的收件箱文件夹中的电子邮件被标记为已读，但我在日志中收到此错误：
rake aborted!
