のLucene：ノルウェーアナライザ - java.lang.NoSuchMethodErrorの：org.apache.lucene.analysis.WordlistLoader.getSnowballWordSet

Question

プロジェクトの展開は、新たに誤りのノルウェーアナライザ

@Fields({ @Field(index = Index.YES, store = Store.YES, analyzer = @Analyzer(impl=NorwegianAnalyzer.class)) 

詳細なスタックトレースを実装した一方で、私は例外を取得していますis：

どのように同じ問題を解決するには？

Answer 1

スタックトレースに記載されているorg.apache.lucene.analysis.no.NorwegianAnalyzerは、予想されるバージョンのorg.apache.lucene.analysis.WordlistLoaderと一致していないようです。

Apache Luceneの最近のバージョンでは、両方のクラスが同じjarに含まれているため、クラスパスにLucene JARのいくつかの重複バージョンがあるようです。

Hibernate Searchが期待するバージョンに一致するApache Luceneバージョンのjarファイルのみを使用してください。
