We are trying to validate a JSON response to see if it matches a schema placed in the Eclipse ClassPath. This is designed to be a Maven project and I believe we have all the dependencies in place. But we are always getting the following error:

java.lang.NoClassDefFoundError: com/github/fge/jsonschema/main/JsonSchemaFactory
    at com.jayway.restassured.module.jsv.JsonSchemaValidatorSettings.<init>(JsonSchemaValidatorSettings.java:58)
    at com.jayway.restassured.module.jsv.JsonSchemaValidator$JsonSchemaValidatorFactory.createSettings(JsonSchemaValidator.java:277)

Caused by: java.lang.ClassNotFoundException: com.github.fge.jsonschema.main.JsonSchemaFactory
    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)

We have the following dependencies in place:

        <dependency>
            <groupId>com.jayway.restassured</groupId>
            <artifactId>rest-assured</artifactId>
            <version>2.9.0</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>com.jayway.restassured</groupId>
            <artifactId>json-schema-validator</artifactId>
            <version>2.9.0</version>
        </dependency>
        <dependency>
            <groupId>com.github.fge</groupId>
            <artifactId>jackson-coreutils</artifactId>
            <version>1.8</version>
        </dependency>
        <dependency>
            <groupId>com.github.fge</groupId>
            <artifactId>json-schema-core</artifactId>
            <version>1.2.5</version>
        </dependency>

Not sure what we are missing here - can someone please help?

Vishnu, Just add following dependencies and remove all above dependencies.

 <dependency>
    <groupId>io.rest-assured</groupId>
    <artifactId>rest-assured</artifactId>
    <version>3.0.1</version>
</dependency>


 <dependency>
    <groupId>io.rest-assured</groupId>
    <artifactId>json-schema-validator</artifactId>
    <version>3.0.1</version>
</dependency>

  • Thanks, Ramu! It worked when I built my .m2 repository again. Seems to me there was a conflict with the latest Rest-Assured version (3.x) versus the old versions (2.x) - since we were experimenting with both, we caught this problem. – Vishnu Vardhan Nov 21 '16 at 23:45
