It seems that you have not included jsf-ipml jar.
To resolve the JSF dependency, you should included JAR dependency as below.
For gradle use
compile 'com.sun.faces:jsf-api:2.2.9'
compile 'com.sun.faces:jsf-impl:2.2.9'
and Maven use
<dependency>
<groupId>com.sun.faces</groupId>
<artifactId>jsf-api</artifactId>
<version>2.2.9</version>
</dependency>
<dependency>
<groupId>com.sun.faces</groupId>
<artifactId>jsf-impl</artifactId>
<version>2.2.9</version>
</dependency>
