Tried reimporting maven/cleared cache nothing seems to be working. Please help

Try this
File -> Invalidate Caches/Restart -> Invalidate And Restart

can you try mvn clean install -U it will force update dependencies

If that's the whole pom, you didn't close the project tag.
Add </project> below </build> and try to load maven changes to update dependencies.

Change https in this line:
https://maven.apache.org/xsd/maven-4.0.0.xsd"

Changing Spring Version in pom.xml

I'm working on a Spring Boot project. Initially, I started with Spring 3.0.0, but the project specification requires the use of version 2.x instead.
I tried to manually change this in line 8 of pom.xml but am now getting an error. How do I correct this?
Correct the classpath of your application so that it contains
compatible versions of the classes
org.springframework.plugin.core.config.PluginRegistriesBeanDefinitionRegistrar
and org.springframework.beans.factory.support.RootBeanDefinition

Driver org.h2.Driver claims to not accept jdbcUrl, jdbc:postgresql://my-previous-db

I try to use H2 database in my new project, before I used postgres. Wrote all data in application.properties, also there is nothing about postgres driver in pom file, only H2 driver, but during auto-configuration each time it tries to connect to my previous database as a result shows this error.

I have no idea what to do, tried to find any info about parent pom.file but had no success
UPDATE: also forgtot that if I specify datasource bean in configuration, everything is ok. But I can't understand where does Spring boot takes the URL to the previos database by Autoconfiguration

This error is attributed to the project have not compile.You use spring-boot-devtools in the project.But the plug-in stops compiling automatically duing running or debugging, at this time need build the project.
You can do this:
Stop the project,delete the target folder and build the project.
Run project and have a try.
You also need check idea conifg adout devtools,something might be wrong.
And you can use Jrebel instead of devtools.

I'm just building a project as part of college assigment.
Do I need to set up the driver?
If I need to what suitable driver will be suitable for only reading and writing json file?

You can try disable autoconfiguration for the datasource and also JPA:
#EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
In addition, if you don't want using database in your application, you can remove JPA dependency in your pom.xml. Just remove:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

I have something very similar to the structure of this project (sfg-pet-clinic), however, after downloading and running mvn package, it works fine. I don't see much difference between the pom files of my project and this one so what could I be missing?

Configuration is for older versions of spring.
Remove:
<configuration>
<skip>true</skip>
</configuration>
Instead, add this flag below pom artifactId
<properties>
<spring-boot.repackage.skip>true</spring-boot.repackage.skip>
</properties>
Like so:
<parent>
<artifactId>mc-pet-clinic</artifactId>
<groupId>guru.springframework</groupId>
<version>0.0.1-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>pet-clinic-data</artifactId>
<properties>
<spring-boot.repackage.skip>true</spring-boot.repackage.skip>
</properties>
...

I would move the entire
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
section from the parent to the module-app module, because that one is the single module which uses the repackage functionality.
Moreower I would delete the plugin section from the module-data too, because there is no need to repackage that module.

Thanks to #wemu on the comments section.
Adding this:
<configuration>
<mainClass> ${your.start.Class}</mainClass>
</configuration>
to the plugin section is required on version 2.1.1.RELEASE of the spring-boot-starter-parent dependency, as long as your class is in another module.
The project sfg-pet-clinic I referred to in my question uses an older version which does not need the <mainClass> configuration

Okay here is how I fixed that.
My Steps were:
Change the packaging of pom.xml file for project-data to pom from
jar (I used overview of Eclipse)
add <type>pom</type> in pom.xml file for project-app for dependency of module-data
<dependency>
<groupId>samee.springframework</groupId>
<artifactId>project-data</artifactId>
<version>0.0.1-SNAPSHOT</version>
<type>pom</type>
</dependency>
Then you can run your clean and package/install

I just changed the Spring Boot version in the parent pom.xml from 2.1.1 to 2.0.3 and it works.
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.3.RELEASE</version>
<relativePath /> <!-- lookup parent from repository -->
</parent>
Would be better to make it work in 2.1.1 though, but that's a quick and simple solution.

Cannot resolve symbol 'SpringBootApplication' - java

Try this File -> Invalidate Caches/Restart -> Invalidate And Restart

can you try mvn clean install -U it will force update dependencies

If that's the whole pom, you didn't close the project tag. Add </project> below </build> and try to load maven changes to update dependencies.
