Add support for configuring web resource directories in Web facets

[ingokegel]

In web projects it is important to be able to configure web resource directories for various purposes.

Because I cannot create a pull request for IntelliJ Ultimate, support on the IDE side has been added in a plugin located at

https://github.com/ingokegel/intellij-web-facet-importer

The plugin has been published in the marketplace:

https://plugins.jetbrains.com/plugin/18139-web-facet-importer

The source code is in the public domain and can be used for IntelliJ Ultimate by JetBrains.

Publishing to Maven Local isn't the best way to test the Gradle plugin.
I'd suggest you add the following line to the settings.gradle file

includeBuild("/path/to/the/Gradle/plugin/sources")

That way, you'll always have the latest sources available with the ability to debug it.

Thank you, that's good to know!

Thank you for your pull request.
IntelliJ IDEA Ultimate supports Gradle-based web projects and should automatically configure web content roots based on information in Gradle's war plugin. What is the purpose of this pull request and the accompanying IDEA plugin?

[ingokegel]

Ok, thank you. How would you add an arbitrary directory to the web resource roots with the war plugin?

[nskvortsov]

According to this example it is sufficient to add from clause to the war configuration:

war {
    webAppDirectory = file('src/main/webapp')
    from 'src/rootContent' // adds a file-set to the root of the archive
   ...
}

OK, thank you, I did not know that. I suppose this is good enough for most situations.
