Add this dependency and remove all other rest assured dependencies. json-path is already included in rest-assured dependency.

<dependency>
    <groupId>io.rest-assured</groupId>
    <artifactId>rest-assured</artifactId>
    <version>5.2.0</version>
    <scope>test</scope>
</dependency>

If you need schema validator you can add:

<!-- https://mvnrepository.com/artifact/io.rest-assured/json-schema-validator -->
<dependency>
    <groupId>io.rest-assured</groupId>
    <artifactId>json-schema-validator</artifactId>
    <version>5.2.0</version>
    <scope>test</scope>
</dependency>

Make sure you have JDK/JAVA_HOME env variable properly installed. The abouve depedencies should work with JDK 8+

  • Getting a new error saying this "SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". SLF4J: Defaulting to no-operation (NOP) logger implementation SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details. " – Ravi Ranjan Nov 12 '22 at 14:13
  • This is warning I believe. You should be able to send request now. You can log it by using this RestAssured.given().log().all().when().get("https://reqres.in/api/users/2"); – Alex Karamfilov Nov 12 '22 at 14:17
  • You can fix the slf4j warning by adding dependencies : org.slf4j slf4j-api 1.7.5 org.slf4j slf4j-log4j12 1.7.5 – Alex Karamfilov Nov 12 '22 at 14:19
