i am configuring the ajax json function in the Spring MVC 3.0 Maven project and get the error message that "nested exception is java.lang.NoClassDefFoundError: com/fasterxml/jackson/core/JsonProcessingException".
So, what should i do to configure the pom.xml to install the needed classes?
Any suggestions would be very helpful!
Add below dependencies to your pom.xml
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>${jackson.version}</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>${jackson.version}</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>${jackson.version}</version>
</dependency>
Replace ${jackson.version} with any version you want,or just add 2.x.xat top of your pom.xml

My Sprint boot application is not coming up because it's complaining about missing class com.fasterxml.jackson.annotation.JsonInclude$Value, but I have jackson library as dependency, so I think it might be possible some conflict.

Has anybody already faced similar issue?

jackson-core,jackson-annotations and jackson-databind jars are automatically added by spring boot.
so you don't need to add them explicitly unless you want to override the version of the jar that are provided by spring boot .
Use the below version for both the artefacts:
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.10.0.pr1</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>2.9.4</version>
</dependency>
Also, update the maven-compiler-plugin version to the latest if maven build fails.
Jackson has made some changes in the method signature of class ObjectMapper, handle the same if implemented.
Am using Rest Template to consume web services in a Maven project and packaged the project to jar to add as a dependency to my other web application
but throwing Exception to console at instantiating the RestTemplate even though i put the code to catch the exception, its directly throwing the below Exception to console. can anyone know the reason?
try{
RestTemplate restTemplate = new RestTemplate(); //getting the Exception here
}
catch(Exception e){
e.printStackTrace(); // but its not coming here
}
the dependenices i have added in my pom.xml file :

You might want to include the correct version jackson-databind jar file in classpath. The servlet container has not started to hit your code base.
Provide all the below dependencies in your pom.xml with same version:
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>${jackson.version}</version>
</dependency>
<dependency>

Has anyone successfully got Spring Boot, Spring Data Elasticsearch, and Elasticsearch 5.x to work?
I updated my pom to use spring-data-elasticsearch 3.0.0.RELEASE (just released) which has commit notes in Github saying it supports ES 5.
I was getting some errors which were caused by not having declared a dependency on spring-data-common. After adding without a version, I noticed it was being managed by Spring Boot apparently and pulls in 1.13.7.RELEASE
This causes: java.lang.NoClassDefFoundError: org/springframework/data/mapping/model/Property
I then bumped up spring-data-common to 2.0.0.RELEASE thinking the newest releases of everything should be compatible. That causes an AbstractMethodError exception when the repository is wired.
Can anyone give any tips? Here are the dependencies from my POM

Whomever edited the title made an inaccurate description. As originally stated, the issue is a "dependency hell". There wasn't missing dependencies but rather a ton of transitive dependencies that all needed versions to be coordinated in magic nonobvious/undocumented ways. – JvmSd121
I once migrated the spring-data-elasticsearch (with ES 2.x) project to use ES 5.x.
I lost the source but I still have the jar here
You guys put me on the right track. I upgraded as follows:
Spring Core (and related): 5.0.0.RELEASE
Spring Boot: 2.0.0.M4
Spring Cloud: Finchley.M2
With those in place, the managed versions get updated as follows:
spring-data-commons: 2.0.0.RC3 (from release-train KAY-RC3)
spring-data-elasticsearch: 3.0.0.RC3 (from release-train KAY-RC3)
elasticsearch and transport: 5.5.2 (meets my 5.x requirement)
We had managed versions of Jackson in our parent pom for other child modules which caused incompatible versions to be pulled in. I overrode those in our Spring Boot projects to the version ${jackson.version} defined in Spring as follows:
spring-jackson-version=2.9.1
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>${spring-jackson.version}</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>${spring-jackson.version}</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>${spring-jackson.version}</version>
</dependency>
I'm getting another error from my repo which I think is self-inflicted due to my data model. All the classpath errors seem to have gone away. I'll give another update if I find anything further. What a cf!
Thanks for the tips.
I'm trying to integrate KeyCloak Admin Client with Spring Boot
But there is an exception is thrown when I was trying to create a new account:
Caused by: javax.ws.rs.ProcessingException: RESTEASY003145: Unable to find a MessageBodyReader of content-type application/json and type class org.keycloak.representations.AccessTokenResponse
So I tried to explicitly register Jackson Provider for KeyCloak like this:
KeycloakBuilder
.builder()
.serverUrl(SERVER_URL)
.realm(REALM)
.username(USERNAME)
.password(PASSWORD)
.clientId(CLIENT_ID)
.resteasyClient(new ResteasyClientBuilder()
.providerFactory(factory.register(ResteasyJackson2Provider.class))
.connectionPoolSize(10)
.build())
.build();
But I'm unable to import ResteasyJackson2Provider.class
pom.xml
<dependency>
<groupId>org.keycloak</groupId>
<artifactId>keycloak-spring-security-adapter</artifactId>
<version>3.1.0.Final</version>
</dependency>
<dependency>
<groupId>org.keycloak</groupId>
<artifactId>keycloak-admin-client</artifactId>
<version>3.1.0.Final</version>
</dependency>
<dependency>

</dependency>
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-jackson2-provider</artifactId>
<version>3.1.3.Final</version>
</dependency>
Btw, if I use resteasy-jackson-provider, I got this exception:
javax.ws.rs.client.ResponseProcessingException: javax.ws.rs.ProcessingException: org.codehaus.jackson.map.exc.UnrecognizedPropertyException: Unrecognized field "access_token" (Class org.keycloak.representations.AccessTokenResponse), not marked as ignorable
at [Source: org.jboss.resteasy.client.jaxrs.internal.ClientResponse$InputStreamWrapper#7cc842b0; line: 1, column: 18] (through reference chain: org.keycloak.representations.AccessTokenResponse["access_token"])
After a while, I figured out the solution to this problem:
Firstly, I tested it out with the standalone project (empty maven project), the problem still occurs because of resteasy-jackson-provider. It should be resteasy-jackson2-provider (note that its resteasy-jackson2-provider)
For now, I was known that the problem somehow comes from Spring Boot, RESTeasy. And finally, I come up with this working pom.xml:
<dependency>
<groupId>org.keycloak</groupId>
<artifactId>keycloak-admin-client</artifactId>
<version>3.1.0.Final</version>
</dependency>
<dependency>
<groupId>org.jboss.resteasy</groupId>

<artifactId>jackson-jaxrs-json-provider</artifactId>

One more thing to note is, you should use the admin-cli client in your Keycloak, because by default, it has Direct Access Grants Enabled on
Btw, this is the Java configuration:
KeycloakBuilder
.builder()
.serverUrl("localhost:8080/auth")
.realm("master")
.username("YOUR_USERNAME")
.password("YOUR_PASSWORD")
.clientId("admin-cli")
.build();

I'm currently writing an Apache Camel project that's using CXF to expose some REST endpoints and Kie Remote Client to interface with BPMS. However, I'm getting a dependency clash (not sure how to describe it) when I try to include the Kie Remote Client dependency into my pom file.
Here's my pom file currently:

Anyone know what's the root cause of this error? Thanks!
EDIT: I did find a temporary workaround to this problem. If I downgrade my camel versions to 2.13.2 and my spring versions to 3.2.8-RELEASE then the apache-cxf versions seem to aligh. However there are many new features that I need in 2.15.2 camel that I would like to keep. Anyone know of any good alternatives to kie.remote.client?
Kie remote client add the jaxb-impl-2.2.5.jar dependency, in collition with jaxb-core-2.2.11.jar and jaxb-impl-2.2.11.jar from cxf.
just remove the jaxb-impl from you deploy. (or use maven exclusion in dependency of kie-client) it's works for me.
