弹性搜索-在java中创建节点/索引时的错误

Question

我正在努力获得概念Java代码工作的证据。我要做的第一件事是在我的HD上索引一些txt文档。然而，在尝试创建Node时，在遇到异常之前，我甚至没有走那么远。

以下代码都会产生以下异常：

码

Node node = nodeBuilder().node();
Client client = node.client();

我的主要问题是：

WHere，我能得到似乎缺少的BoundaryScanner类吗？我将在异常下面提供maven pom.xml。lucene-快速矢量荧光程序包似乎是最新版本的3.0.3。

任何帮助都很感激。

Answer 1

在同一个项目中混合不同版本的Lucene组件并不是一个好主意。您应该使用3.6.0进行任何操作。最近的版本中有一些更改，因此您需要替换/删除一些工件。例如，斯诺球分析器现在在lucene-分析器中，所以您不应该需要lucene-雪球工件，lucene-快速矢量荧光笔现在在lucene-荧光笔中：

      <dependency>
        <groupId>org.apache.lucene</groupId>
        <artifactId>lucene-core</artifactId>
        <version>3.6.0</version>
      </dependency>           

      <dependency>                  
        <groupId>org.apache.lucene</groupId>
        <artifactId>lucene-analyzers</artifactId>   
        <version>3.6.0</version>                            
      </dependency>                                               

      <dependency>
        <groupId>org.apache.lucene</groupId>
        <artifactId>lucene-highlighter</artifactId>
        <version>3.6.0</version>
