Question

这让我觉得很荒谬，但是我似乎无法将多个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，我得到以下内容：

请注意，第一个jar文件mysql jar文件已添加到类加载器中，但未添加第二个jar文件oracle jar文件。我也试过两次使用-cp参数：

 groovyConsole -cp ~/lib/compile/jar/mysql-connector-java-5.1.32.jar -cp ~/lib/compile/jar/ojdbc6-11.2.0.3.jar

但是这只是因为错误而失败了。除了模糊的提示之外，文档显然没有任何指导，因为它的工作原理就像Java一样。因此，为什么它的第一次尝试如此令人沮丧并没有开箱即用。

我还尝试使用Script＆gt;启动groovyConsole后添加Jar文件;将Jar添加到类路径菜单选项，但它不添加任何jar文件。

那么为什么这种工作不能更直接地进行呢？

Groovy类路径是是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的功能，您可能必须在Unix上用单引号引起来，以防止扩展。

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

这使我花了很长时间才找到：https://docs.oracle.com/javase/8/docs/technotes/tools/windows/classpath.html#A1100762

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