groovy - 如何将多个jar添加到groovyConole/groovysh的类路径中？

Question

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？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，我得到以下结果:

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。因此，为什么第一次尝试没有开箱即用，令人如此沮丧。

我还尝试使用“脚本”>“将 Jar 添加到类路径”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 的一项功能，您可以在 Unix 上必须将其括在单引号中以防止它被扩展。即:

groovyConsole -cp $HOME/lib/compile/jar/* 

这花了我令人不安的很长时间才找到:https://docs.oracle.com/javase/8/docs/technotes/tools/windows/classpath.html#A1100762
