java.lang.ClassNotFoundException: org.springframework.cache.guava.GuavaCache

Context -
I have a spring boot app and
I updated the spring-boot-starter-parent version from 1.5.12.RELEASE to 2.4.0
I had this dependency in my pom -
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>30.1-android</version>
</dependency>
Now when I am running my app, I am getting this error -
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'cachesEndpoint' defined in class path resource ...
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'guavaCacheManager' defined in class path resource...

I resolved this by completely removing guava dependency and its references from my project.
If you still need to use caching then try using Caffeine.

With some more research over the web, I was able to fix the same exception which was occurring in my project by adding spring-context-support to the project.
I did it by adding following dependency to my build.gradle:
compile("org.springframework:spring-context-support:4.1.7.RELEASE")
spring-context-support is a library that contains helper methods and classes for configuring the cache.
Here is the blog that I followed:

Unable to load the voltage class java.lang.NoClassDefFoundError: com/voltage/securedata/enterprise/VeException

I am trying to encrypt / decrypt messages using libvibesimplejava.so of 6.21 version where I have added the dependencies to load the jar from system path when I deployed to dev instance it's throwing this error:
Caused by: java.lang.NoClassDefFoundError: com/voltage/securedata/enterprise/VeException
Caused by: java.lang.ClassNotFoundException: com.voltage.securedata.enterprise.VeException

Below is the code for library instantiation
Loading Library -
static {
System.load("src/main/resources/****/libvibesimplejava.so");
}
Library context instanitiation -
LibraryContext library = new LibraryContext.Builder()
.setPolicyURL(policyURL)
.setFileCachePath(cachePath)
.setTrustStorePath(trustStorePath)
.setClientIdProduct("****",
"***")
.build();

<version>6.21.0.0</version>

<systemPath>${basedir}/src/main/resources/****/lib/vibesimplejava.jar</systemPath>
</dependency>
Why it is failing to load the class in dev? Could any one suggest me the way to resolve this issue?

NoClassDefFoundError error creating RestHighLevelClient bean

I'm getting an error creating a HighEndRestClient bean in a SpringBoot app. I have done a test 'app' where I checked I can instantiate the objects I want and then make the calls I want to and I am now making baby steps into making a new application.
I have these dependencies in the pom
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-client</artifactId>
<version>5.6.3</version>
</dependency>
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>elasticsearch-rest-high-level-client</artifactId>
<version>5.6.3</version>
</dependency>
and I have written this very basic code in a configuration class which doesn't do much yet
#Configuration
#PropertySource(value = "classpath:application.properties")
#EnableElasticsearchRepositories(basePackages = "com.indexbuilder.es.repo")
public class ElasticsearchConfiguration {
#Value("${elasticsearch.host}")
private String EsHost;
#Value("${elasticsearch.port}")
private int EsPort;
#Value("${elasticsearch.clustername}")
private String EsClusterName;
#Bean
public RestClientBuilder coreBuilder() throws Exception {
RestClientBuilder builder = RestClient.builder(new HttpHost("localhost", 9200, "http"));
builder.setMaxRetryTimeoutMillis(10000);
builder.setFailureListener(new RestClient.FailureListener() {
#Override
public void onFailure(HttpHost host) {
System.out.println("FAILURE !!!! FailureListener HAS WOKEN UP!!!! CREATYE A FAILURE LISTENER BEAN" );
}
});
return builder;
}
#Bean
public RestClient restLowLevelClient() throws Exception{
RestClient restClient = coreBuilder().build();
return restClient;
}
This works fine as far as I can see (I haven't done much with it yet...)
when I add this (initially I was passing in the RestClient bean but now I'm temporarily creating a local object for more clarity)
#Bean
public RestHighLevelClient restHighLevelClient() throws Exception{
RestClient restClient = coreBuilder().build();
RestHighLevelClient client = new RestHighLevelClient(restClient);
return client;
}
I get this java.lang.NoClassDefFoundError error

Can anyone point me in the right direction ?

You probably need the core dependency as well:
<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
<version>5.6.3</version>
</dependency>
A NoClassDefFoundError is generally a configuration error - it means that the code you use references a certain class, but the class itself isn't in the classpath. In this case, this might also be a dependency management error in the relevant Elasticsearch poms themselves, as they should include the needed classes - but there's not much you can do about that other than perhaps file an issue.

I had the same problem.
ElasticSearch pointed to old version:
org.elasticsearch:elasticsearch:6.2.3 -> 1.5.2
I used dependencyManagement gradle plugin to force use the version I mention:
dependencyManagement {
dependencies {
dependency 'org.elasticsearch:elasticsearch:6.2.3'
}}

Spring Boot Integration Testing

I have been trying to write a integration test for a small Spring boot Project that I have written but for some reason seem unable to get integration tests to work. Here is what I am trying to do:
package au.azzmosphere.integration;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
#RunWith(SpringJUnit4ClassRunner.class)
#SpringBootTest(classes = {IntegrationTestConfiguration.class})
public class TestIntegration1 {
#Test
public void testDummy() {
}
}
the configuration class has the following:
package au.azzmosphere.integration;
import au.azzmosphere.configuration.RobotAppConfig;
import org.springframework.context.annotation.Configuration;
#Configuration
public class IntegrationTestConfiguration extends RobotAppConfig {
}
The code is consistently getting the following errors when I try to run the Integration Test from IntelliJ
14:54:01.537 [main] DEBUG org.springframework.test.context.junit4.SpringJUnit4ClassRunner - SpringJUnit4ClassRunner constructor called with [class au.azzmosphere.integration.TestIntegration1].

14:54:01.549 [main] INFO org.springframework.test.context.TestContextManager - #TestExecutionListeners is not present for class [class au.azzmosphere.integration.TestIntegration1]: using defaults.
From gradle the following is returned

Worked it out, :) The problem was that I did not have any TransactionDefinition defined because I didn't use it. The default SpringBoot annotation attempts to inject it. The answer was to use #TestExecutionListeners({DependencyInjectionTestExecutionListener.class}) which overrides the defaults and gets things going.

I need to find a proper way how to use camel cdi and access same camel context in different projects.

#coolD, I also had the same issue and found a way to handle this. I have used Apache Camel 2.16.2 with camel CDI. I have added my answer in other stackOverFlow Question. How to use same CamelContext in multiple jar on the same war Have a look. That might help.
ps. There is a camel 2.17.0 has been released out. I have not tried out yet.

Take a look at the various CDI examples
https://github.com/apache/camel/tree/master/examples
There is also an improved camel-cdi component as part of Camel 2.17.
