我正在使用LensKit推荐器在Netbeans中构建一个maven项目,但是当我尝试运行一个groovy文件时,我收到以下错误:

你能提出任何解决方案吗? 如果我需要发布任何其他信息,请告诉我。

更新!
好的,我已经更新了第一条错误消息,下面是异常的堆栈跟踪:

2 个答案:

答案 0 :(得分:1)

看起来NetBeans正在使用Codehaus exec-maven-plugin来直接运行LensKit eval.groovy文件作为Groovy脚本。 LensKit eval脚本无法直接作为Groovy脚本运行,必须使用LensKit评估程序运行。

有两种方法可以做到这一点:

  • 使用评估程序命令行界面,或者使用二进制分发版中的lenskit-eval脚本,或者运行NetBeans中的org.grouplens.lenskit.eval.cli.EvalCLI类。
  • 使用lenskit-eval-maven-plugin。你的POM已经设置好了;您将为此选项执行的操作是运行lenskit-analyze Maven目标(NetBeans应该有办法运行任意Maven目标/阶段)。
