IDEA import of Maven GitHub projects not working/running -> "Cannot resolve symbol"

#### UPDATE v2 ####

Ok I found out the issue, it was in fact an IDEA bug. More precisely, it's the git extension, gitflowincrementalbuilder, which from 3.8+ breaks Idea. Changing version to 3.7 solves it, for now.

https://github.com/vackosar/gitflow-incremental-builder/issues/91

Intellij/git, please fix it

------ Old Update v1 -----

I just tried running the project with Eclipse... works perfectly without any issues whatsoever, at first try... So it's kind of a Intellij-IDEA bug/problem (...)

I am trying to run some examples from Github, the spring spring-boot ones from baeldung.com; more specifically this one (no one works in idea): https://github.com/eugenp/tutorials/tree/master/spring-mvc-simple-2

While it works using Maven commands, "mvn clean install" and then "mvn spring-boot:run", wont work in Idea (it does clean and install ok, but no run). Project is imported using "New"->"Project from Existing Sources" (check images below for settings).

I think there is some problem with the pom imported configuration, especially since there is a multi module structure (parent tag); cannot even resolve @SpringBootApplication. 

<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"
xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<modelVersion>4.0.0</modelVersion>
<artifactId>spring-mvc-simple-2</artifactId>
<packaging>war</packaging>
<name>spring-mvc-simple-2</name>

<parent>
    <groupId>com.baeldung</groupId>
    <artifactId>parent-boot-2</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <relativePath>../parent-boot-2</relativePath>
</parent>

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
        </plugin>
    </plugins>
    <finalName>spring-mvc-simple2</finalName>
</build>

I have been trying to add a SpringBoot configuration manually using IDEA gui but it doesnt recognize the application class (?). What partially works though is replacing the parent pom with:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.4.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

Tests still wont work, but I dont think u're supposed to change/edit the pom file manually to make things works...

I have been trying alot already: invalidate cache, maven reimport & Generate sources and update folders, using mvn first, checking all jdk configuration... nothing works.

You didn't build the parent module so IntelliJ does not find this in your local Maven repository.

You should run mvn install in the project: https://github.com/eugenp/tutorials/blob/master/parent-boot-2/pom.xml

But also exchanging the parent helps like you described yourself.

To make the tests run you have to add the test dependency from the parent:

    <dependency>  
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>io.rest-assured</groupId>
        <artifactId>rest-assured</artifactId>
    </dependency>
