Exception in thread "main" java.lang.NoSuchMethodError: org.slf4j.helpers.MessageFormatter.format(Ljava/lang/String;Ljava/lang/Object;)Lorg/slf4j/helpers/FormattingTuple;Jcr2davRepositoryFactory

I was getting the below exception while connecting to the AEM JCR repository through Java API(JCR webdav) using Jcr2davRepositoryFactory.

Exception in thread "main" java.lang.NoSuchMethodError: org.slf4j.helpers.MessageFormatter.format(Ljava/lang/String;Ljava/lang/Object;)Lorg/slf4j/helpers/FormattingTuple;

To fix the issue add the slf4j-log4j12 with the lower version and also exclude jcl-over-slf4j from jackrabbit-jcr2dav dependency.

<dependency>

 <groupId>org.slf4j</groupId>

    <artifactId>slf4j-log4j12</artifactId>

    <version>1.5.0</version>
