web.xml not found in Java EE7 project

问题

I'm doing a project in eclipse with JSF 2.2 and Servlet 3.1 (Java EE7). The first problem I had was a error in the pom.xml in line:

<packaging>war</packaging>

Error: web.xml is missing and is set true.

I researched on the internet and added the following lines in my pom.xml

<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.4</version>
    <configuration>
        <failOnMissingWebXml>false</failOnMissingWebXml>    
    </configuration>
</plugin>

After that the error was gone, but when running the project get the error:

java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config

I searched the Internet again and put the following lines in pom.xml

<dependency>    
    <groupId>jstl</groupId> 
    <artifactId>jstl</artifactId>
    <version>1.2</version>
</dependency>

The problem solved, only when access for example:

http://localhost:8080/MeuSistema/Login.jsf

(I put mapped as jsf to inves xhtml)

He changes the jsf by jsp stating the following:

HTTP Status 404 - /MeuSistema/Login.jsp

Out of curiosity changing the .jsf to .xhtml to see if opened at least the file, it returns the following:

HTTP Status 404 - Not Found /Login.xhtml in ExternalContext as a Resource

I also found this alternative to force to read the web.xml

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.4</version>
    <configuration>
        <webxml>src/main/webapp/WEB-INF/web.xml</webxml>
        <warSourceDirectory>src/main/webapp/</warSourceDirectory>
    </configuration>
</plugin>

But the problems remain the same.

Follow my pom.xml and web.xml:

Well, it seems that is not reading the web.xml. Funny that in not of any console error.

What can be wrong? Thanks for attention.

Simply add below line to pom.xml of your project.

<properties>        
<failOnMissingWebXml>false</failOnMissingWebXml>    
</properties>
