"JavaServer Faces 2.2 requires Dynamic Web Module 2.5 or newer."

I am using Eclipse for Java EE and AWS Toolkit for Eclipse v2. I'm on a macOS Mojave Version 10.14.5. I have Java 8 installed.

I get errors when I first create an AWS Java Web Project that say "JavaServer Faces 2.2 can not be installed : One or more constraints have not been satisfied." and "JavaServer Faces 2.2 requires Dynamic Web Module 2.5 or newer." as seen in this screenshot:

enter image description here

Here is webproject01/pom.xml:

Here is the web.xml file:

<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"

</web-app>

I would like to get to the point where I can deploy my AWS Java Web Project to AWS via AWS Elastic Beanstalk right from Eclipse.

I have looked at other similar posts on stackoverflow and tried their solutions, but none of them work. They were older posts.

Not sure what AWS toolkit has to do with this, but you have to fix your pom.xml to use/include javax.servlet version higher than 2.5. Probably should post that here. If you don't have a pom.xml then you need to edit the project properties but you will be much better off starting with a reasonable maven archetype. – K.Nicholas
@K.Nicholas I've tried that as instructed by other posts similar to this one. It looks like I might have to learn more about Maven. I don't even know what an archetype means. I just followed instructions to use Eclipse for Java with AWS Toolkit. – Daniel Brower
@K.Nicholas I just put the pom.xml files in the original post. That is before I tried adding other content in them to try to fix the problem. – Daniel Brower
Well, your javaee-api dependency should have scope provided. I don't see anything in the AWS-Eclipse-Toolkit about Java EE so I think you are trying something that will ultimately just continue to give you troubles. If you want to play with cloud and Java EE I recommend you open a free account at openshift.com and play there. It will be very Java EE oriented. – K.Nicholas
The second one = scope provided. – K.Nicholas

Maybe someone will be useful.

In case you are using JBoss Tools, then instead of setting the JSF facet for the project

Properties -> Project Facets -> JavaServer Faces (2.3)

it is better to use another option:

Properties -> JBoss Tools Knowledge Base -> JBoss Tools Knowledge Base Support

If you enable this option, then Eclipse auto-completion (content assist) for XHTML (JSF) pages will work fine.

You need to upgrade your web.xml to present a newer version:

<web-app 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/web-app_3_1.xsd"
         version="3.1">
</web-app>

You're currently saying that your web app is a servlet version 2.3 app.
