我想为Weka添加自定义分类器。此分类器位于 jar 文件中。我已将其放入Weka文件夹并运行此命令java -classpath "D:/weka/ancl.jar;D:/weka_bin/weka.jar" weka.gui.GUIChooserWeka 运行正常，但我在分类器列表中找不到我的分类器。
我也尝试过将此分类器转换为 GenericObjectEditor.props 文件，但是当我使用上面的逗号运行 weka 时，当我点击资源管理器按钮时，我会收到此异常
$ java -classpath "D:/weka/ancl.jar;D:/weka_bin/weka.jar" weka.gui.GUIChooser

谁能告诉我 Weka 中的自动类发现是如何工作的？或者为什么它实际上没有:(任何帮助都已批准
在创建 jar 时，将Java_cup、Meta_Inf 和 weka 文件夹合并在一起，然后上述错误将消失。
我按照这些说明进行操作，一切都很好：
https://waikato.github.io/weka-wiki/writing_classifier/
快速浏览到最后：
下面是对 weka.classifiers.trees.Id3 和生成的类 weka.classifiers.WekaWrapper 的示例调用（它将实际生成的代码包装在伪分类器中）：
java weka.classifiers.CheckSource
-W "weka.classifiers.trees.Id3"
-S weka.classifiers.WekaWrapper
-t data.arff
-c last
