This question already has an answer here:
I want to migrate from jsf 2.1 to 2.2 but I can not run my server (Tomcat) to couse of the following error: (I'm yours to inform you that I used [Hibernate + Spring + JSF] in project Maven)

This parameter tells MyFaces if javascript code should be allowed in
the rendered HTML output.
If javascript is allowed, command_link anchors will have javascript code
that submits the corresponding form.
If javascript is not allowed, the state saving info and nested parameters
will be added as url parameters.
Default is 'true'</description>

<param-value>true</param-value>
</context-param>
<context-param>
<description>
If true, rendered HTML code will be formatted, so that it is 'human-readable'
i.e. additional line separators and whitespace will be written, that do not
influence the HTML code.
Default is 'true'</description>

<description>
If true, a javascript function will be rendered that is able to restore the
former vertical scroll on every request. Convenient feature if you have pages
with long lists and you do not want the browser page to always jump to the top
if you trigger a link or button action that stays on the same page.
Default is 'false'

See @BalusC answer here about the same problem. You have two jsf implementations in your pom.xml: myfaces and mojarra. So myfaces is conflicting with mojarra. Remove one of them
<!-- MyFaces -->
<dependency>
<groupId>org.apache.myfaces.core</groupId>
<artifactId>myfaces-api</artifactId>
<version>2.2.2</version>
</dependency>
<dependency>
<groupId>org.apache.myfaces.core</groupId>
<artifactId>myfaces-impl</artifactId>
<version>2.2.2</version>
</dependency>

or
<!-- Mojarra -->
