-CDI deployment failure- maven project on NetBeans 8.1

I create a maven web application on Netbeans IDE 8.1.Then, i add some ressources(js,css,...) and a web page index.html

Also i add these dependencies to pom.xml file

<dependency>
        <groupId>org.apache.mahout</groupId>
        <artifactId>mahout-core</artifactId>
        <version>0.8</version>
    </dependency>
    <dependency>
        <groupId>org.apache.mahout</groupId>
        <artifactId>mahout-integration</artifactId>
        <version>0.8</version>
    </dependency>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.25</version>
    </dependency>

This is the error:

Grave:   Exception while loading the app
    Grave:   Undeployment failed for context /SecondAppPfa
    Grave:   Exception while loading the app : CDI deployment failure:WELD-001408: Unsatisfied dependencies for type Set<Service> with qualifiers @Default

I found a solution :

just add beans.xml file under META-INF folder

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee 
       http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
       bean-discovery-mode="all">
</beans>
