如何将多个jar添加到groovyConole/groovysh的类路径中? [英] How to add multiple jars to the classpath of groovyConole/groovysh?
问题描述
我不得不问这个问题，这很荒谬，但是我似乎无法向groovyConsole和groovysh的类路径中添加多个jar文件.如何将多个jar文件添加到类路径?这是我尝试过的:
This feels ridiculous that I have to ask this, but I can't seem to add multiple jar files to the classpath for groovyConsole and groovysh. How do I add multiple jar files to the classpath? Here is what I've tried:
groovyConsole -cp〜/lib/compile/jar/mysql-connector-java-5.1.32.jar:〜/lib/compile/jar/ojdbc6-11.2.0.3.jar
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，会得到以下信息:
However, when I execute this code in the console I get the following:

请注意，第一个jar文件(即mysql jar文件)已添加到类加载器中，但未添加第二个jar文件(即oracle jar文件).我也尝试过两次使用-cp参数，例如:
Notice that the first jar file, the mysql jar file, is added to the classloader, but the second jar file, the oracle jar file, is not added. I've also tried using the -cp argument twice like:
groovyConsole -cp ~/lib/compile/jar/mysql-connector-java-5.1.32.jar -cp ~/lib/compile/jar/ojdbc6-11.2.0.3.jar
但这只会失败并显示错误.这些文档明显没有任何指导，只是模糊地暗示它像Java一样工作.因此，为何如此令人沮丧的首次尝试无法立即使用.
But that just fails with an error. The docs are conspicuously devoid of any guidance other than vague hints that it works just like Java. Hence why its so frustrating the first attempt didn't work out of the box.
在尝试使用脚本>将Jar添加到类路径菜单选项启动groovyConsole之后，我还尝试添加Jar文件，但是没有添加任何jar文件.
I've also tried to add the Jar files after starting groovyConsole using Script > Add Jar(s) to Class path menu option, but it adds none of the jar files.
那为什么不以更直接的方式工作呢?
So why doesn't this work in a more straight forward manner?
推荐答案
Groovy类路径是Java类路径，并且您可以使用通配符将所有JAR包含在目录中(请注意，这是不是Unix通配符，而是Java的功能，您可能必须在Unix上用单引号将其引起来，以防止扩展.
The Groovy classpath is the Java classpath, and you can include all the JARs in a directory using a wildcard (note the this is not the Unix wildcard, but a feature of Java, and you may have to enclose it in single quotes on Unix to prevent it from being expanded. To wit:
groovyConsole -cp $HOME/lib/compile/jar/*
This took me a disturbingly long time to locate: https://docs.oracle.com/javase/8/docs/technotes/tools/windows/classpath.html#A1100762
