jdk version: 17
I'm trying to use j48 in weka for study it, but I got two problems.
First, I run the Run.java, and the complier throw a error: complier can not find java_cup package. So I follow this tutor to install java_cup package, it's successful.
Second, CPUTask.java in java_cup package have another problem: complier can not find org.apache.tools.ant package. So I follow this video to install it. about 5:40 in video, I type "ant -version" in terminal, and show a sentence like a error.
Sorry about that it is Chinese. in English, it said: "must not have Files\FLC_Tools\java_cup_draw_tree now." but it is the package I have to install.
How should I fix this problem? I have to install java_cup and ant package both.
This is error line in CPUTask.java
