执行mvn sql:execute时出错

我希望 Maven 执行该 sql 文件，它生成的数据库模式稍后将在我的程序中使用。但它不起作用，可能是由“DELIMITER”引起的。当我执行“mvn sql:execute”时，它会打印出

[ERROR] Failed to execute:  DELIMITER $$

这是我的 pom.xml 的一部分

            </configuration>
        </plugin>

这是我的sql文件的一部分

DELIMITER $$

USE `jellyjolly_schema`$$
DROP TRIGGER IF EXISTS `jellyjolly_schema`.`delete_user` $$
USE `jellyjolly_schema`$$


CREATE TRIGGER delete_user
AFTER DELETE
ON jj_users
FOR EACH ROW
BEGIN
    ## delete the posts that belong to the user
    DELETE FROM jj_blog_posts WHERE author_user_id=OLD.user_id;
END
$$

是否是因为 Maven 调用的 MySQL Java 连接器不支持关键字“DELIMITER”。那么我该如何解决呢？

阅读您的评论后，我相信最好的解决方案是在这里接受 https://stackoverflow.com/questions/13072354/sql-maven-plugin-with-multiple-delimiters。也就是说，仅使用一个分隔符（最好是默认的，;）并使用sql-maven-plugin配置为要求分隔符出现在自己的行上实际上是一个分隔符。

    &ltconfiguration;>
      &ltdelimiterType;&gtrow;</delimiterType>
    </configuration>

（归功于 @Zheka https://stackoverflow.com/users/794494/zheka)

您的触发器将如下所示：

CREATE TRIGGER delete_user
AFTER DELETE
ON jj_users
FOR EACH ROW
BEGIN
    ## delete the posts that belong to the user
    DELETE FROM jj_blog_posts WHERE author_user_id=OLD.user_id; # this delimiter is ignored
END
; # this delimiter is recognized
