我不得不问这个问题，这感觉很荒谬，但我似乎无法将多个 jar 文件添加到 groovyConsole 和 groovysh 的类路径中。 如何将多个 jar 文件添加到类路径中？ 这是我尝试过的：
groovyConsole -cp ~/lib/compile/jar/mysql-connector-java-5.1.32.jar:~/lib/compile/jar/ojdbc6-11.2.0.3.jar
但是，当我在控制台中执行此代码时，我得到以下信息：

请注意，第一个 jar 文件（mysql jar 文件）已添加到类加载器中，但第二个 jar 文件（oracle jar 文件）未添加。 我还尝试使用 -cp 参数两次，例如：
groovyConsole -cp ~/lib/compile/jar/mysql-connector-java-5.1.32.jar -cp ~/lib/compile/jar/ojdbc6-11.2.0.3.jar
但这只是失败并出现错误。 除了模糊地暗示它的工作原理与 Java 一样之外，这些文档显然没有任何指导。 这就是为什么第一次尝试没有开箱即用的结果如此令人沮丧。
我还尝试使用 Script > Add Jar(s) to Class path 菜单选项启动 groovyConsole 后添加 Jar 文件，但它没有添加任何 jar 文件。
那么为什么这不能以更直接的方式工作呢？
Groovy 类路径是 Java 类路径，您可以使用通配符将所有 JAR 包含在目录中（请注意，这不是 Unix 通配符，而是 Java 的一个功能，您可能必须将其用单引号引起来在 Unix 上防止它被扩展：
groovyConsole -cp $HOME/lib/compile/jar/'*'
