java - Problems with rendering JSP in spring boot

I have a Spring boot application where I want to use jsp

Here are my dependencies in pom.xml

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.4.0.M2</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <java.version>1.8</java.version>
</properties>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <dependency>
        <groupId>org.jsoup</groupId>
        <artifactId>jsoup</artifactId>
        <version>1.8.3</version>
    </dependency>
    <dependency>
        <groupId>javax.mail</groupId>
        <artifactId>mail</artifactId>
        <version>1.5.0-b01</version>
    </dependency>
    <dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-jasper</artifactId>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>jstl</artifactId>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-mail</artifactId>
    </dependency>

    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <scope>runtime</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

When I try to load JSP page which has 

<!Doctype html>

then the page is partially shown correctly, but not fully - for example 

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java"
     pageEncoding="UTF-8"%>
<%@taglib uri="http://www.springframework.org/tags" prefix="spring"%>

is displayed on the screen.

When I delete <!Doctype html> - then I see only plain html, no view.

I tried to add and delete dependencies and if I add or delete 

    <dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-jasper</artifactId>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>jstl</artifactId>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-el</artifactId>
        <scope>provided</scope>
    </dependency>

nothing really changes - I still receive either plain html or partially visible jsp.

I have the same problem both when I run it in IntellijIdea and when I run compiled jar

I am stuck here and it feels like I won't ever make it :( I looked at huge amount of tutorials and as many questions on StackOverflow as I could found with no help.

Any advice is very much appreciated!

UPDATE When I use pom.xml from https://github.com/spring-projects/spring-boot/blob/master/spring-boot-samples/spring-boot-sample-web-jsp/pom.xml I get this error

Did you ever solve your problem? I assume that most of the above guys were getting the project to work using the IDE. Its very different when you run the project as a jar.

Our JSPs are in //project//src/main/resources/META-INF/resources/WEB-INF/jsp/index.jsp All the pom includes you have is the same as ours. However I've found that Spring boot 1.4.3 and above stops supporting the embedded JSPs, maybe they want to force us to use thymeleaf;) I've just reverted to Spring boot 1.4.1 and the JSPs work perfectly from a jar.
