Answer 1

That mistake web.xml not found is a mistake of maven-war-plugin, there is the file web.xml? If it does not exist and should not exist, configure the plugin to

<failOnMissingWebXml>false</failOnMissingWebXml>

Adding this inside the project -> plugins:

<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.6</version>
    <configuration>
        <filteringDeploymentDescriptors>false</filteringDeploymentDescriptors>
    </configuration>
</plugin>

Note: just check the version of your plugin

Answer 2

In case of error in War you must click with the right mouse on 1 - Project explorer 2 - Right Boot in deplyment Descriptor 3 - generate Deployment Descriptor stub

Create an xml file that fixes the error, if it persists, create the file again.
