Question

我有以下非常简单，有目的错误的java类：

import java.io.InputStream;
import java.util.*;
public class ArrayListError{

public ArrayListError(){
}
public static void makeArray(int i){
ArrayList list = new ArrayList(i);
}
public static void main(String[] args)
{
System.out.println("Enter a number to create arrayList:");
Scanner scanner =new Scanner(System.in);
int i= scanner.nextInt();
makeArray(i);
}

}

在evosuite cygwin上运行时（java -jar evosuite-20120511.jar -setup c：/ Users / Eliezer \ Shindler / Desktop / myclasses）我明白了：

线程“main”java.lang.ExceptionInInitializerError中的异常 at de.unisb.cs.st.evosuite.setup.ScanProject.main（ScanProject.java:578）引起：com.thoughtworks.xstream.converters.ConversionException：无法构造de.unisb.cs.st.evosuite.callgraph.DistanceTransformer $ ClassEntry，因为它没有no-args构造函数：无法构造de.unisb.cs。 st.evosuite.callg raph.DistanceTransformer $ ClassEntry，因为它没有no-args构造函数 ----调试信息---- 消息：无法构造de.unisb.cs.st.evosuite.callgraph.Distanc eTransformer $ ClassEntry，因为它没有no-args构造函数 cause-exception：com.thoughtworks.xstream.converters.reflection.ObjectAcces sException cause-message：无法构造de.unisb.cs.st.evosuite.callgraph.Distanc eTransformer $ ClassEntry，因为它没有no-args构造函数 class：java.util.HashSet required-type：de.unisb.cs.st.evosuite.callgraph.DistanceTransformer $ Clas sEntry 路径：/set/de.unisb.cs.st.evosuite.callgraph.DistanceTransformer $ ClassEntry

我不明白这一点 - 任何人都可以请求帮助 - 我多年来一直在努力解决这个问题。有关evosuite文档的信息，请访问www.evosuite.org/documentation

Answer 1

我认为这是一个内部的evosuite错误，由于某种原因，在cygwin中运行它。

运行EvoSuite时出现ExceptionInInitializerError（java的自动单元测试生成）
