Java NoSuchMethodError:org.apache.lucene.document.Field

我有另一个项目，jena全文搜索，但我在运行时出错。错误如下所示：

我能得到一些建议吗？谢谢

我猜您有Lucene 8.0或更高版本，Jena似乎还不支持。确保您对Jena的任何版本都使用了正确的lucene版本：

尝试对您的项目进行干净的构建，然后再试一次。。您甚至可以检查jar，并可能通过删除jar文件来调整应用程序，查看预期的jar是否正在引用。。。另外，您使用的是什么版本的Lucene。我不熟悉Lucene，但类似的错误可能是某个特定版本的局部错误，并且可能是在未来版本中修复的已知问题。。你为什么不试试另一个版本呢？@parthi我已经将Lucene的版本降级为6.4.0。谢谢你的帮助！很高兴听到它起作用，我从来没有注意过。我降级到了Lucene 6.4.0，它可以正常工作。谢谢你的帮助！
