Java 无法将Synset解析为类型

堆栈跟踪：

Synset cannot be resolved to a type
26:             String wordForm = buffer.toString();
27:             //  Get the synsets containing the wrod form
28:             WordNetDatabase database = WordNetDatabase.getFileInstance();
29:             Synset[] synsets = database.getSynsets(wordForm);
30:             //  Display the word forms and definitions for synsets retrieved
31:             if (synsets.length > 0)

你的导入看起来像什么？导入edu.smu.tspell.wordnet.*；导入edu.smu.tspell.wordnet.Synset；导入edu.smu.tspell.wordnet.WordNetDatabase；这很奇怪-如果找不到类型，我希望导入会失败。您确定在同一个文件中有这些导入失败吗？
