代码：
public int run() throws IOException, ClassNotFoundException, InterruptedException, URISyntaxException
{
job.addCacheArchive(new URI(CACHE + "#length0ids"));
}
protected void setup(Context context)
{
FileReader fr = new FileReader("length0ids");
BufferedReader br = new BufferedReader(fr); String line = null;}
网上找了很多方法都没有用，这时不妨看看项目文件夹下是否有名为缓存文件名的类似快捷方式的文件，删除之，bug解决。
