I try to learn using HTTPClient. But HttpClient client = HttpClient.newHttpClient(); does not work.
In IntelliJ I've updated my compiler to use Java version 12 and in the pom.xml I've set java.version property to 12.
After I write HTTPClient it gets import sun.net.www.http.HttpClient, and then newHttpClient() method does not work. For this method I need import java.net.http.HttpClient;
This is my pom.xml:
<properties>
<java.version>12</java.version>

It works now. I installed java Version 13 on my comuter and edites in Project Structure
You should add this dependency to your POM.xml

I am using the latest version of the hibernate validator package in my maven project. My pom file contains this
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>7.0.4.Final</version>
<scope>compile</scope>
</dependency>
When I use version 6, everything works fine, but with version 7, the following method throws an error.
private void addValidationError(ConstraintViolation<?> cv) {
this.addValidationError(
cv.getRootBeanClass().getSimpleName(),
((PathImpl) cv.getPropertyPath()).getLeafNode().asString(),
cv.getInvalidValue(),
cv.getMessage());
}
The error is with the cast to PathImpl. Hovering over the error I get this message:
Inconvertible types; cannot cast 'javax.validation.Path' to 'org.hibernate.validator.internal.engine.path.PathImpl'
When I navigate to the PathImpl class, I can see that the file (in the jar that has been automatically downloaded and is of course not controlled by me) does not compile because these two lines in it are erroring
import jakarta.validation.ElementKind;
import jakarta.validation.Path;
The error is
Cannot resolve symbol 'jakarta'
Am I doing something wrong?

You are trying to mix Java EE with Jakarta EE.
With the most recent version the namespaces have changed from javax to jakarta.
Make sure that your dependencies are all up to date and use the same version.
Important notice
You are using Spring Boot. And Spring Boot will be ready for Jakarta EE with version 3!
So you cannot use any dependency that is using something from the jakarta namespace.
Additionally with Spring Boot you shouldn't override the version that comes with it.
It's because of namespace changing from javax to jakarta in newer versions of Jakarta EE specifications. You should use older version of hibernate-validator (as you said) or just update Jakarta platform dependency as for compatibility:
<dependency>
<groupId>jakarta.platform</groupId>
<artifactId>jakarta.jakartaee-api</artifactId>
<version>8.0.0</version>
<scope>provided</scope>
</dependency>

I do not understand why this error happens and I have tried to remove scope variable as well. My project structure displays Maven:junit:4.12 so I cannot understand why it can't find the required dependency
When you're new to Spring Boot then let Spring Initializr create your pom.xml. It will create a working pom.xml.
I used a spring initializr project for creating a REST service (https://spring.io/guides/gs/intellij-idea/) and imported it in IntelliJ using Maven project.
That works fine. Unit tests run fine too.
Now, I added some code and imported another package (org.apache.zookeeper). IntelliJ does not seem to get that dependency. The compile error says (Error:(11, 28) java: package org.apache.zookeeper does not exist)
Moreover, I ensured that the pom.xml is updated and the effective POM as shown by Intellij lists the same package (scope - compile).
I checked that the Maven settings does not have anything odd, basically empty with the standard root tags.
Here is the POM -

For Intellij Idea: go to Maven(on right side) and press "Reimport All Maven Project".
it worked for me.
Right click on your project folder -> Maven -> Reload Project.
It worked for me
Right click on project and Follow this Navigation
project->maven->reimport will worked for me
I have a spring boot reactive application generated from spring starter. It should use the Netty server by default but I can see that the tomcat has started on port 8080 in the console.

I have choose some parts of pom.xml not entire pom.xml is included.
Below is the class for Spring-boot main app.
#SpringBootApplication
#EnableWebFlux
public class SpringWebFluxDemoApplication {
public static void main(String[] args) {
SpringApplication.run(SpringWebFluxDemoApplication.class, args);
}
}
Is there anything else missing ? I think it should boot up with Netty only.
if you want netty instead as explained in documentation documentation
you've to exclude tomcat and include netty :
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-rest</artifactId>

I have followed this
https://docs.spring.io/spring-boot/docs/2.1.1.RELEASE/reference/html/howto-embedded-web-servers.html
and I have excluded tomcat dependencies, rebuild the project. it was up and running on netty.
