ElasticSearch 2.0 Java API: java.lang.ClassNotFoundException: org.elasticsearch.common.settings.ImmutableSettings $ Builder

Question

I updated my Spring boot project to use the new ElasticSearch 2 API, and I get this error on startup:

Caused by: java.lang.NoClassDefFoundError: org/elasticsearch/common/settings/ImmutableSettings$Builder
    at java.lang.Class.getDeclaredMethods0(Native Method)
    at java.lang.Class.privateGetDeclaredMethods(Class.java:2701)
    at java.lang.Class.getDeclaredMethods(Class.java:1975)

My respective Maven dependencies:

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
        <version>1.3.0.M5</version>
    </dependency>
    <dependency>
        <groupId>org.elasticsearch</groupId>
        <artifactId>elasticsearch</artifactId>
        <version>2.0.0-rc1</version>
    </dependency>

Do you have any hint at what I'm doing wrong?

thanks

In ES 2.0, the class is ImmutableSettingsreally removed. This question mentions this, and violation of documentation of changes for version 2.0 also mention this.

Settings.builder() ImmutableSettings.builder(). Settings

, - ImmutableSettings, - 2.0 Elasticsearch.
