gephi toolkit ver0.10.1でsaveProjectが上手く動かない場合の回避策。saveProjectの手前で、save_file.createNewFile() と空のファイルを作る。

Main.java

package org.gephi.toolkit.save_test;

public class Main {

    public static void main(String[] args) {
        SaveProject saveProject = new SaveProject();
        saveProject.script();
    }
}
