我目前正在尝试在 Tomcat 上部署最新的 Sakai 12.1 实例，但是当我运行

mvn clean install sakai:deploy -Dmaven.tomcat.home=$CATALINA_HOME -Dsakai.home=$CATALINA_HOME/sakai -Dsakai.cleanup=true -Djava.net.preferIPv4Stack=true命令，如果在“Sakai Core Kernel Implementation”模块（413 之外）之前执行没有错误，则返回：

...

我已经看到了错误日志，第一个是在 RoleAccessTest 测试中。日志信息：

...
13:29:15,161   INFO PoolBase:505 - sakai - Driver does not support get/set network timeout for connections. (not supported feature)
13:29:15,168  ERROR PoolBase:441 - sakai - Failed to execute connection test query (insufficient user privileges or object not found: DUAL).
13:29:15,169  ERROR HikariPool:541 - sakai - Exception during pool initialization.
java.sql.SQLSyntaxErrorException: insufficient user privileges or object not found: DUAL
        at org.hsqldb.jdbc.JDBCUtil.sqlException(Unknown Source)
        ...

[编辑：查看前面的日志，为什么 HSQLDB 会出现在错误堆栈中？不应该只是 MySQL 吗？] 后来，在另一行：

WARN JdbcServicesImpl:195 - HHH000341: Could not obtain connection metadata

Mysql Driver JAR 已正确复制/opt/tomcat/lib，并且 DB 用户和凭据已正确设置在/opt/tomcat/sakai/local.properties

我不想在没有运行测试的情况下部署 Sakai，因为这是一个全新的安装，不应该有任何错误......

有什么帮助吗？

查看您的sakai.properties或local.properties。它可能有这条线

# validationQuery@javax.sql.BaseDataSource=select 1 from DUAL

这是 Sakai 默认发出的用于检查数据库是否可达的 SQL 查询。看起来您正在使用的数据库系统不支持该查询，因此您需要将该属性设置为其他查询，或者切换您正在使用的数据库系统。MySQL 支持这个查询，所以如果你有

vendor@org.sakaiproject.db.api.SqlService=mysql

我错了，它一定是别的东西。
