htmlunit爬虫遇到的坑 'application/javascript'

警告: Expected content type of 'application/javascript' or 'application/ecmascript'

         for remotely loaded JavaScript element at 'http://jquery-1.4.2.min.js', but got ''.

java.lang.NoSuchMethodError:org.apache.commons.io.IOUtils.toString(Ljava/io/InputStream;Ljava/nio/charset/Charset;)Ljava/lang/String;

解决：

版本太高，换成低版本。
