无法从命令行生成java：org.jooq.exception.DetachedException：无法执行查询。没有连接配置

Question

我试图从我的数据库生成JOOQ Java代码。

当我执行

java -cp "bla.xml;jooq-3.5.0.jar;jooq-meta-3.5.0.jar;jooq-codegen-3.5.0.jar;jtds.jar" org.jooq.util.GenerationTool bla.xml 

我得到：

org.jooq.exception.DetachedException: Cannot execute query. No Connection configured 
     at org.jooq.impl.AbstractQuery.execute(AbstractQuery.java:303) 

我不知道为什么它不会生成Java代码。 的启动表示：

     <!-- All elements that are generated from your schema (A Java regular expression. 
      Use the pipe to separate several expressions) Watch out for 
      case-sensitivity. Depending on your database, this might be 
      important! 

      You can create case-insensitive regular expressions using this syntax: (?i:expr) 

      Whitespace is ignored and comments are possible. 
      --> 
     <includes>.*</includes> 

     <!-- All elements that are excluded from your schema (A Java regular expression.

您使用JTDS作为驱动程序实现，但是一个SQL Server JDBC驱动程序URL：

jdbc:sqlserver://localhost:1433;databaseName=x 

的jTDS连接URL格式略有不同。从本质上讲，你错过了jtds:前缀和数据库名称是由前缀/：

jdbc:jtds:sqlserver://localhost:1433/x
