I need a bit of assistance in creating a GWT project from scratch and importing the project into my IntelliJ Ultimate.

More exactly here is what I had tried so far:
a)
- I had installed the GWT-Plarform into my IntelliJ via MarketPlace.
- And when I had tried to create a project using the plugin, I can't pass this window because of the archetypes that never appear in the "Select Archetype" list. I had waited for 5 minutes and still nothing.
I was inspired by the You Tube video https://www.youtube.com/watch?v=fhguru8i0VI .
b) Besides this, I had also tried a second approach by creating a Maven project that uses the archetype described here https://docs.sencha.com/gxt/4.x/guides/getting_started/maven/Archetypes.html
And got stocked at the version number. I don't know with what value to fill the version field in the pop-up window. I had tried 1.0.2, 1.0.3-SNAPSHOT and other versions but none of them had worked.
c) And lastly but not least I had tried the way the official documentation by downloading the GWT SDK and by using the creating the project using the command line. ( e.g webAppCreator -out foo -templates maven,sample,readme com.example.foo.Foo )
After this, I went into this new project (with the terminal) and run the command mvn gwt:compile. And the output was full of errors.
Please help.
