[JSF] - Erro ao executar aplicação

Programação
#1

Olá javeiros!
Estou tentando executar a minha aplicação JSF + Primefaces porém ela apresenta a seguinte mensagem de erro:
java.lang.IllegalStateException: Could not find backup for factory javax.faces.context.FacesContextFactory. javax.faces.FactoryFinder$FactoryManager.getFactory(FactoryFinder.java:1135) javax.faces.FactoryFinder.getFactory(FactoryFinder.java:379) javax.faces.webapp.FacesServlet.init(FacesServlet.java:350) org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:502) org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:79) org.apache.catalina.valves.AbstractAccessLogValve.invoke(AbstractAccessLogValve.java:617) org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:518) org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1091) org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:668) org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1527) org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.run(NioEndpoint.java:1484) java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) java.lang.Thread.run(Thread.java:745)

Já pesquisei na internet e nos artigos que encontrei, está dizendo que, provavelmente, no projeto possuem várias libs referentes ao jsf, mas no meu projeto existe apenas uma ‘javax.faces-api-2.2.jar’ que se caso eu retira-la começa a estourar erros de compilação, segue a lista de libs do meu projeto:
