使用Java应用程序中的groovy库

Question

我正在制作Java应用程序。 我导入的其中一个.jar库正在使用Groovy。 当我尝试使用该库时，我得到以下异常：

java.lang.NoClassDefFoundError: groovy/lang/GroovyObject

我知道这个库已成功用于其他Java项目。 图书馆的来源目前无法使用。 我使用Groovy enVironment Manager安装了groovy。 从我的终端groovysh工作。 我需要检查一些其他设置，以找出我收到此错误的原因吗？ 完整的堆栈跟踪：

最简单的方法是添加：

~/.gvm/groovy/X.X.X/embeddable/groovy-all-X.X.X.jar 

到你的类路径
