json-schema-validator jar包冲突

项目中使用json-schema-validator库对json进行校验，同时引入了json-patch对schema进行patch，如果将json-schema-validator的mvn依赖放到json-patch的下面，就会出现jar包冲突的问题，从而报错。

如下：

<dependency>
    	    <groupId>com.github.java-json-tools</groupId>
    	    <artifactId>json-patch</artifactId>
    	    <version>1.13</version>
    </dependency>
    
    <dependency>
    	  <groupId>com.github.fge</groupId>
    	  <artifactId>json-schema-validator</artifactId>
          <version>2.2.6</version>
    </dependency>

运行json-validator的校验方法

ProcessingReport report = JsonSchemaFactory.byDefault().getValidator()
    					.validateUnchecked(schemaJson, responseJson);

报如下错误：

Exception in thread "main" java.lang.NoSuchMethodError: com.github.fge.jackson.JsonNumEquals.getInstance()Lcom/google/common/base/Equivalence;

    	at com.github.fge.jsonschema.main.JsonSchemaFactory.byDefault(JsonSchemaFactory.java:113)

经过mvn dependency检查，发现是由于jackson-coreutils冲突造成。解决方法，将json-path依赖放到json-schema-validator上面即可。
