java.lang.NoClassDefFoundError: net/minidev/json/writer/JsonReaderI

I've put together a simple TestNG exercise using JsonPath but it doesn't complete the parsing to get the ReadContext owing to a class its unable to load:

java.lang.NoClassDefFoundError: net/minidev/json/writer/JsonReaderI
at com.jayway.jsonpath.internal.DefaultsImpl.(DefaultsImpl.java:17)
at com.jayway.jsonpath.internal.DefaultsImpl.(DefaultsImpl.java:15)
at com.jayway.jsonpath.Configuration.getEffectiveDefaults(Configuration.java:48)

at com.jayway.jsonpath.internal.JsonContext.(JsonContext.java:52)
at com.jayway.jsonpath.JsonPath.parse(JsonPath.java:596)

I'm using the suggested reference to 2.1.0 in my pom file.

Any suggestions?

@pengboyin Looks like JsonSmart is missing on class path.

I encountered this error while I was running a junit test. I add json-smart and asm to my pom.xml, then the error dissapeared.

        <dependency>
            <groupId>net.minidev</groupId>
            <artifactId>asm</artifactId>
            <version>1.0.2</version>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>net.minidev</groupId>
            <artifactId>json-smart</artifactId>
            <version>2.2.1</version>
            <scope>test</scope>
        </dependency>

But How can I add the json-smart if I just use the jason-path-2.4.0.jar? Thanks a lot.

I have already figures it out. Yes, when the json-smart, asm and accessors-smart are added. Then the error also disapear. Thanks also.

I am having similar errors even after adding the above mentioned dependencies to my spring-boot pom file. My app was always working all the sudden I started seeing these error while running my spring boot app from eclipse.
