错误：

不知道怎么解决。jdk是1.7的。引入的zxing包也是用jdk1.7打包的。
MyEclipse编译。

import com.google.zxing.client.j2se.MatrixToImageWriter的方法writeToPath 在将ArrayList<?>转换为Collection<BlockPair>失败

BitMatrix bitMatrix =new MultiFormatWriter().encode(content, BarcodeFormat.QR_CODE, width, height,hints); 原来我是漏了一个hints参数 但现在代码已经没有报错了。但是编译还是出错 Exception in thread "main" java.lang.Error: Unresolved compilation problem: at com.google.zxing.common.CharacterSetECI.getCharacterSetECIByName(CharacterSetECI.java:114) at com.google.zxing.qrcode.encoder.Encoder.encode(Encoder.java:95) at com.google.zxing.qrcode.QRCodeWriter.encode(QRCodeWriter.java:78) at com.google.zxing.MultiFormatWriter.encode(MultiFormatWriter.java:102) at com.zxing.CreatQRCode.main(CreatQRCode.java:30) 求解决啊。谢谢

是在慕课网上照着打得。本人小白。求各位大神指教啊，基本方法都用过都没解决掉这个，估计是类型，泛型的问题
