推荐答案

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/

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