本文整理了Java中groovy.lang.GroovyShell类的一些代码示例，展示了GroovyShell类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。GroovyShell类的具体详情如下：
包路径：groovy.lang.GroovyShell
类名称：GroovyShell

GroovyShell介绍

[英]Represents a groovy shell capable of running arbitrary groovy scripts
[中]表示能够运行任意groovy脚本的groovy shell

代码示例

/**
 * Loads a set of given beans
 * @param resources The resources to load
 * @throws IOException
 */
