json-smart NoclassDefFoundError

[teddykwon]

I use spring-boot 1.5.1 RELEASE

I find bug that "net.minidev:json-smart:2.2.1" is default "testCompile"

I Solved it by adding compile("net.minidev:json-smart:2.2.1")

please check.

Hi @teddykwon
This dependency is not officially managed by Spring Boot (you can find the list here) and we don't provide any specific support about it.

This may be a transitive dependency of one of our test dependencies, but I can't even find it at the moment. You can probably trace its origin with the mvn dependency:tree command.

If you rely on that dependency in your application (and since it's not managed by Boot), you should explicitly declare that dependency and manage it yourself.

[wilkinsona]

I was just looking at something similar (SpringDataWebConfiguration is involved here). json-smart is a transitive dependency of com.jayway.jsonpath:json-path and that's how it's being used here. 2.2.1 is the latest version of json-smart and is what json-path depends on by default. There must be another dependency or some dependency management that it downgrading it to an older, incompatible version.

[teddykwon]

@wilkinsona Yes!! I want talk that. I couldn't explain occur because I can't write english well.

[wilkinsona]

@teddykwon Just to be clear, I agree with @bclozel. I was just providing a bit more explanation as I'd been looking at something very similar. You'll need to figure out why your app is using an older version of json-smart and correct it.

[teddykwon]

I find it. The cause is aws-java-sdk.

I make test project and test dependencies.

First.

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.5.1.RELEASE")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'

jar {
    baseName = 'spring-boot-test'
    version =  '0.0.1'
}

repositories {
    mavenCentral()
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")
    // tag::actuator[]
    compile("org.springframework.boot:spring-boot-starter-actuator")
    // end::actuator[]
    // tag::db[]
    compile("org.springframework.boot:spring-boot-starter-data-jpa")
    compile("com.h2database:h2")
    // end::db[]
    testCompile("junit:junit")
}

It work fine.

Second

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.5.1.RELEASE")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'

jar {
    baseName = 'gs-spring-boot'
    version =  '0.1.0'
}

repositories {
    mavenCentral()
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")
    // tag::actuator[]
    compile("org.springframework.boot:spring-boot-starter-actuator")
    // end::actuator[]
    // tag::db[]
    compile("org.springframework.boot:spring-boot-starter-data-jpa")
    compile("com.h2database:h2")
    // end::db[]
    // tag::aws[]
    compile("com.amazonaws:aws-java-sdk:1.11.86") // it's include json-path:2.2.0
    // end::aws[]
    testCompile("junit:junit")
}

dependencies :

     +--- com.amazonaws:aws-java-sdk-stepfunctions:1.11.86
     |    +--- com.jayway.jsonpath:json-path:2.2.0
     |    |    \--- org.slf4j:slf4j-api:1.7.16 -> 1.7.22

Thanks.

[wilkinsona]

Thanks for following up. So it's being excluded completely rather than being the wrong version.

Here's the relevant part of the pom for aws-java-sdk-stepfunctions:

<dependency>
    <artifactId>json-path</artifactId>
    <exclusions>
        <exclusion>
            <artifactId>json-smart</artifactId>
            <groupId>net.minidev</groupId>
        </exclusion>
    </exclusions>
    <groupId>com.jayway.jsonpath</groupId>
    <optional>false</optional>
    <version>2.2.0</version>
</dependency>

Excluding a required dependency is a rather strange thing to do. I guess they only use JSON path in such a way that json-smart isn't needed. That's rather risky and a bit anti-social but there's not much we can do about it.

[teddykwon]

@wilkinsona Thanks for comments. I learned a lot thanks to it.

[anjo-swe]

We are having same issues now with Spring Boot 1.5.2 & AWS SDK

@wilkinsona you got a link to pom section you pasted in your previous comment? Wasn't able to locate it.

@teddykwon any other solution? Adding that dependency to all our projects using AWS SDK is a bit messy

Thanks
Andreas

[teddykwon]

1. add build.gradle

compile("net.minidev:json-smart:2.2.1")

2. exclude module "net.minidev"

compile ("com.amazonaws:aws-java-sdk:1.11.14") {
    exclude module: "net.minidev"
    compile group: 'com.googlecode.json-simple', name : 'json-simple', version: '1.1'
 }

I used second solution. @anjo-swe

[wilkinsona]

@anjo-swe http://central.maven.org/maven2/com/amazonaws/aws-java-sdk-stepfunctions/1.11.86/aws-java-sdk-stepfunctions-1.11.86.pom

[anjo-swe]

Thanks @wilkinsona

Note: This is not case with newer versions of AWS SDK, e.g. http://central.maven.org/maven2/com/amazonaws/aws-java-sdk-stepfunctions/1.11.121/aws-java-sdk-stepfunctions-1.11.121.pom
