Can I run an empty spring boot application without getting an Error?

I just Created this file from spring.initializer.
It is a brand new file. I am trying to run this because I have a previous project that have similar type of error. So I thought of making a new project and see if any error comes. below i the Error

I See this
java.lang.NoClassDefFoundError: org/hibernate/boot/model/naming/CamelCaseToUnderscoresNamingStrategy
Caused by: java.lang.ClassNotFoundException: org.hibernate.boot.model.naming.CamelCaseToUnderscoresNamingStrategy
Couple of solutions
Check if you have this class CamelCaseToUnderscoresNamingStrategy under your Maven dependencies -> org.hibernate dependency -> path boot/model/naming
If you can't locate that class, add a hibernate dependency with version >= 5.5.4
Check if this article helps Spring boot application and hibernate are using different naming strategies

I deleted the Hibernate folder from C:\Users{User}.m2\repository.
Then I added below dependency in the pom file.
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.5.4.Final</version>
</dependency>
Also add version to maven plugin -:
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
**<version>${project.parent.version}</version>**
</plugin>
Do the above steps if anyone gets the same Error.

package does not exist while deploying

I'm trying to run a Talend job from Java code!
I followed the instructions from https://help.talend.com/reader/Lod~TDRaNw2L2VZKV9XgZw/ty4l9kEdDoVHlHIAOW1e~Q
and it works perfectly when i run it, but i can't deploy it on heroku
my code :
package com.example.demo;
import local_project.addcase_0_1.addCase;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
#SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
#RestController
class HelloController {
#GetMapping("/")
public String TestJob() {
addCase a = new addCase();
a.runJob(new String[] {});
return "Added";
}
}

Spring cloud netflix eureka server - tomcat error on startup

this is my first question at stackoverflow, so I try my best to describe everything in detail.
I have a simple spring-cloud-starter-netflix-eureka-server gradle based project which should only start the eureka server inside a docker container.
I am really new to spring. I tried some older versions of spring cloud starter but nothing worked.
I am building the jar on ubuntu 18.04 with openjdk 10.
It would be really nice if someone could help me!
Thanks a lot!
My SpringBootApplication class looks like this:
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
#SpringBootApplication
#EnableEurekaServer
public class EurekaServiceRegistryApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaServiceRegistryApplication.class, args);
}
}
Here is my build.gradle:
plugins {
id 'java'
id 'org.springframework.boot' version '2.0.3.RELEASE'
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
dependencies {
compile group: 'org.springframework.cloud', name: 'spring-cloud-starter-netflix-eureka-server', version: '2.0.0.RELEASE'
}
And my dockerfile:
FROM openjdk:8-jre-alpine
ADD ./build/libs/eureka-service-registry-1.0-SNAPSHOT.jar /app/
CMD ["java", "-jar", "/app/eureka-service-registry-1.0-SNAPSHOT.jar"]
EXPOSE 8761
When I run my docker container (and also when I start the application from within IntelliJ) I get the following:

I've had the same problem.that spring-boot version must one-to-one match eureka version.you can reference to http://projects.spring.io/spring-cloud/
example:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.12.RELEASE</version>
<parent>
<dependencyManagement>
<dependencies>
<dependency>

<artifactId>spring-cloud-dependencies</artifactId>
<version>Dalston.SR5</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>

You need to select proper spring boot and spring cloud version. Also, i was getting error for jettison hence added dependency for jettison to resolve this.
<parent>

Thank you so much for your comments! I first added the spring-boot-starter-web, then the error changed to something with gson.
The answer from here solved my problem at the end.

Spring Boot sample throws MojoExecutionException in eclipse

I am studying spring security and AngularJS using this tutorial. Part One of the tutorial specifies very specific changes to the pom.xml. But when I add those pom.xml changes, an error results.
In eclipse, the error is a compilation error message as follows:
Plugin execution not covered by lifecycle configuration: ro.isdc.wro4j:wro4j-maven-plugin:1.7.6:run (execution: default, phase: generate-resources)
which appears at the following line in pom.xml:
<execution> <!-- this line throws the compilation error in eclipse -->
<phase>generate-resources</phase>
<goals>
<goal>run</goal>
</goals>
</execution>
When I try to bypass eclipse by running mvn spring-boot:run on the CentOS terminal, the following stack trace results:
[root#localhost demo]# mvn spring-boot:run
[INFO] lots of INFO lines
[INFO] folder: /home/user/workspace_angular/demo/target/generated-resources/static/css

Note there is an address already in use error mixed in the above stack trace. At first, I thought the error might be due to a port 8080 conflict when restarting the program, but the problem persists even when I run shutdown.sh and startup.sh to restart tomcat. Also, note that the message at the end of the stack trace indicates that a plugin within pom.xml might be causing the problem, which you can verify by clicking on this link.

I created the project in eclipse with the Spring Tool Suite add ons by selecting File > New > Project... > Spring > Spring Starter Project with only the default parameters, and then following the instructions in the above-linked tutorial explicitly.
The instructions in the tutorial worked until I added the changes to pom.xml shown above and articulated in part one of the tutorial.
So what do I have to do to get the program to compile?

When you execute mvn spring-boot:run it has its own embedded Tomcat, so it does not need separated Tomcat instance to run, thus you have conflict between this two Tomcat.
You have to just run: shutdown.sh and left it this way and try again.

Deploying a Spring boot app to Heroku

I've been recently trying to deploy an app to Heroku, but it has been proven to be a nightmare to do so. I've got a little web app that works just fine when run locally on my computer, but when run on Heroku, it complaints about a number of errors and I dont have an idea why. I've spent good 10 hours trying to figure out whats going on, but I'm no wiser :/
This is the error I'm getting on Heroku:
