Hi,  
I am trying to develop a spring boot based elasticsearch project and I am trying to use Java High Level Rest Client in the same.  
I am initializing the client like this:

```auto
RestHighLevelClient client = new RestHighLevelClient(
				RestClient.builder(
                                    new HttpHost("localhost", 9200, "http"), 
                                    new HttpHost("localhost", 9201, "http"))
                                  );

```

But I am encountering an exception caused by:

```auto
Caused by: java.lang.ClassNotFoundException: org.apache.lucene.util.Version
	at java.net.URLClassLoader.findClass(URLClassLoader.java:381) ~[na:1.8.0_151]
	at java.lang.ClassLoader.loadClass(ClassLoader.java:424) ~[na:1.8.0_151]
	at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:335) ~[na:1.8.0_151]
	at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ~[na:1.8.0_151]
	... 54 common frames omitted

```

My pom.xml has the following dependencies:

```auto
        <dependency>
			<groupId>org.elasticsearch</groupId>
			<artifactId>elasticsearch</artifactId>
			<version>6.2.2</version>
		</dependency>
        <dependency>
			<groupId>org.elasticsearch.client</groupId>
			<artifactId>elasticsearch-rest-high-level-client</artifactId>
			<version>6.2.2</version>
		</dependency>

```

I have also tried adding

```auto
	<repositories>
		<repository>
			<id>elastic-lucene-snapshots</id>
			<name>Elastic Lucene Snapshots</name>
			<url>http://s3.amazonaws.com/download.elasticsearch.org/lucenesnapshots/00142c9</url>
			<releases>
				<enabled>true</enabled>
			</releases>
			<snapshots>
				<enabled>false</enabled>
			</snapshots>
		</repository>
	</repositories>

```

as mentioned in the documentation but the exception is still there.  
I have also checked the **mvn dependency:tree** and lucene-core and other dependencies are there.  
Please help me out.

Please format your code, logs or configuration files using `</>` icon as explained in [this guide](https://discuss.elastic.co/t/about-the-elasticsearch-category/21) and not the citation button. It will make your post more readable.

Or use markdown style like:

````
```
CODE
```

````

There's a live preview panel for exactly this reasons.

Lots of people read these forums, and many of them will simply skip over a post that is difficult to read, because it's just too large an investment of their time to try and follow a wall of badly formatted text.  
If your goal is to get an answer to your questions, it's in your interest to make it as easy to read and understand as possible.

Please update your post and remove all the **bold** (`**`) you tried to add.

Hi David,

Much better. Thanks!

Can you share the full `dependency:tree` ?

Nothing looks wrong as far as I can tell. May be share a minimalist sample project on github we can look at?

Note: I never tried with Spring boot yet with the High Level client. That's on my TODO list though 🙂

Hi David,  
I have pushed a basic version of the project on github.  
Please find it here [SpringBoot-ES](https://github.com/navneet35/springboot-es)

</div>

Well, I solved it.  
**RCA**  
Actually, it all started when I included

```auto
        <dependency>
			<groupId>org.elasticsearch.client</groupId>
			<artifactId>elasticsearch-rest-high-level-client</artifactId>
			<version>6.2.2</version>
		</dependency>

```

and it uses `elasticsearch:5.6.8` and `joda-time:2.9.9.` then I started getting following exception

```auto
java.lang.ClassNotFoundException: org.joda.time.format.ISODateTimeFormat

```

To eliminate that I included

```auto
        <dependency>
			<groupId>org.elasticsearch</groupId>
			<artifactId>elasticsearch</artifactId>
			<version>6.2.2</version>
		</dependency>

```

and then I started getting

```auto
Caused by: java.lang.ClassNotFoundException: org.apache.lucene.util.Version
	at java.net.URLClassLoader.findClass(URLClassLoader.java:381) ~[na:1.8.0_151]
	at java.lang.ClassLoader.loadClass(ClassLoader.java:424) ~[na:1.8.0_151]
	at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:335) ~[na:1.8.0_151]
	at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ~[na:1.8.0_151]
	... 54 common frames omitted

```

Actually, the problem was not with Lucene but with `joda-time:2.9.9` in the first place.  
So, to solve that include

```auto
		<dependency>
			<groupId>joda-time</groupId>
			<artifactId>joda-time</artifactId>
			<version>2.9.4</version>
		</dependency>

```

and remove

```auto
        <dependency>
			<groupId>org.elasticsearch</groupId>
			<artifactId>elasticsearch</artifactId>
			<version>6.2.2</version>
		</dependency>

```

from your pom.xml.
