java - 是什么导致错误 ' A SPI class of type lucene.codecs.Codec name ' Lucene42'

Question

无法弄清楚是什么原因导致 ' 名称为“Lucene42”的 org.apache.lucene.codecs.Codec 类型的 SPI 类不存在。您需要将支持此 SPI 的相应 JAR 文件添加到您的类路径中'

任何帮助将不胜感激

请添加以下文件

文件夹:META-INF/services/

文件:org.apache.lucene.codecs.Codec

文本:org.apache.lucene.codecs.lucene54.Lucene54Codec

请在 https://anwaarlabs.wordpress.com/2017/02/25/lucene-an-spi-class-of-type-org-apache-lucene-codecs-codec-with-name-does-not-exist/ 查看带有详细说明的解决方案

此解决方案是为 Lucene5.4 定义的，它也适用于 Lucene 4.2。谢谢
