Can't use Java client due to NoClassDefFoundError: org/apache/log4j/Priority

[fakeh]

I had to add these dependencies to resolve:

        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>log4j-over-slf4j</artifactId>
            <version>1.5.11</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-nop</artifactId>
            <version>1.7.21</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>1.7.21</version>
        </dependency>

Elasticsearch version: 5.0.0-alpha4

JVM version: java version "1.8.0_60" Java(TM) SE Runtime Environment (build 1.8.0_60-b27) Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)

OS version: OSX 10.11.5

Description of the problem including expected versus actual behavior: Can't use Java client, due to NoDefFound from ESLogger.

Steps to reproduce:

1. Create Maven project
2. Depend on

        <dependency>
            <groupId>org.elasticsearch</groupId>
            <artifactId>elasticsearch</artifactId>
            <version>5.0.0-alpha4</version>
        </dependency>

1. Try to make a client:

    private Client client = TransportClient.builder().build().addTransportAddress(
            new InetSocketTransportAddress(new InetSocketAddress("localhost", 9300)));

Provide logs (if relevant):

So at the moment, the best solution is @ctron 's cluge (thanks @ctron !!) ? Or am I missing something in this too long thread?

[miscenko]

@ctron , thanks a lot!

Whilst the guys here spent LOT of time meta-discussing usage of the right words in the discussion, @ctron made it! You are the absolute winner, bro!
