I’m having a problem trying to upgrade hibernate search. I had ti working previously but now I’m getting the following error no matter what I do.

```auto

SEVERE: Servlet [fvap] in web application [/ROOT] threw load() exception

Most of the time, if you get a `NoSuchMethodError`, the cause is a JAR in your classpath with the wrong version.

Here, I think you are importing a version of `hibernate-search-engine` that is not `6.0.9.Final`.

The cause is your double dependency to both Hibernate Search 5 and Hibernate Search 6:

```auto
<dependency>
			<groupId>org.hibernate</groupId>
			<artifactId>hibernate-search-orm</artifactId>
			<version>${hibernate.orm.version}</version> <!-- 5.4.0.Final -->
		</dependency>
                <!-- .... -->
		<dependency>
			<groupId>org.hibernate.search</groupId>
			<artifactId>hibernate-search-mapper-orm</artifactId>
			<version>${hibernate-search.version}</version> <!-- 6.0.9.Final -->
		</dependency>

```

You end up with two copies of `org.hibernate.search.engine.Version` in your classpath, and here it seems Hibernate Search 6 accessed the copy of `Version` from Hibernate Search 5. Which, obviously, doesn’t work.

Anyway… Don’t use both Hibernate Search 5 and Hibernate Search 6 in the same application. Remove this from your POM:

```auto

<dependency>
			<groupId>org.hibernate</groupId>
			<artifactId>hibernate-search-orm</artifactId>
			<version>${hibernate.orm.version}</version>
		</dependency>

```

Seems like this question was copied from Stackoverflow: [java.lang.NoSuchMethodError: 'java.lang.String org.hibernate.search.engine.Version.versionString()' - Stack Overflow](https://stackoverflow.com/q/72064421/6692043)

Closing, continuing the discussion (if any) on Stackoverflow.
