麻煩各位大大幫忙小弟如何解決與並還要安裝什麼語言才可測試..

此外eclipse測試下列三種都會有bug:
import org.apache.lucene.document.Document;
import org.apache.lucene.document.Field;
import org.apache.lucene.index.IndexWriter;
不知eclipse還要安裝什麼檔案才可執行]]> https://forum.andowson.com/posts/preList/470/970 https://forum.andowson.com/posts/preList/470/970 GMT
