使用 ij 工具工作 java 代码拒绝连接到 Derby 数据库 10.11.1.1

Question

目前我有一个 Derby 数据库...版本 10.11.1.1 通过 Java 应用程序创建，该应用程序仅在 java 应用程序运行任意查询与之通信时才起作用。 Maven依赖如下：

   <dependency>
        <groupId>org.apache.derby</groupId>
        <artifactId>derby</artifactId>
        <version>10.11.1.1</version>
   </dependency>

当我尝试使用 ij 工具或任何其他第三方应用程序时：

i.e. connect 'jdbc:derby:/home/username/dev/db-agents/TESTDB';

无法执行，抱怨用错了版本，如下：

Caused by: java.sql.SQLException: Database at /home/username/dev/db-agents/TESTDB has an incompatible format with the current version of the software.  The database was created by or upgraded by version 10.11.

我不明白为什么我只能从 Java 应用程序进行连接，而不能进行其他操作？我有什么特别不对的地方吗？

您的 ij 会话使用的是旧版本的 Derby。

这由您运行 ij 时设置的 CLASSPATH 控制。

仔细查看您用来启动 ij 的脚本或命令，看看它是哪个版本的 Derby 运行ning。

然后调整您在 run ij 时使用的 CLASSPATH，以便它使用 Derby 10.11，这是您的 Java 应用程序正在使用的版本。
