我已经下载了几乎所有可以找到的 JDBC 驱动程序版本以及多个版本的 JAVA。

每次我尝试运行 SchemaSpy 时，都会收到以下错误：

@texnoob 我在尝试使用旧数据库类型运行 SchemaSpy 时看到了这一点。尝试使用更高版本的 SQL Server-t mssql08而不是。-t mssql

使用命令行开关运行 SchemaSpy-dbhelp应该返回支持的类型，但它对我不起作用。查找类型的另一种方法是在允许您浏览存档（WinZip、WinRAR 等）的应用程序中打开 SchemaSpy JAR 文件。打开后，您将在路径“BOOT-INF\classes\org\schemaspy\types”中找到列出的数据库类型。

如果更改数据库类型仍然不起作用，请提供您发出的命令行语句以供进一步分析。
