[jira] [Commented] (DAFFODIL-2835) sbt for DFDL schema projects is not usable without internet connection

["Mike Beckerle (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DAFFODIL-2835?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17877041#comment-17877041 ] 

Mike Beckerle commented on DAFFODIL-2835:
-----------------------------------------

This is also important for training classes where the class is not connected to the internet.

In that case the .ivy2 cache materials have to be packaged and available so trainees have time to acquire and install these. 

Offline access to things like the Apache Daffodil web site, and the Confluence Wiki, is also needed.

Attached is a PDF export of the confluence wiki for your consideration. [^DAFFODIL-260824-2226-198342.pdf]

> This is not a Daffodil bug. There is no issue with using sbt for Daffodil development.
> This is a bug with the way we depend on sbt as our standard build tool for DFDL schema authors to use. 
> sbt requires internet connectivity or so it seems, perhaps it can be setup to NOT do this, that would provide a workaround or fix for this issue. 
> Certainly if sbt finds a build.properties file that specifies a different sbt version be used, then it tries to download that from the internet. 
> Our users require that they can do DFDL schema authoring, testing, etc. in secure air-gapped networks with no internet connectivity. 
> We need to either figure out how to use sbt without the need to have an internet connection, or we need to switch to a tool that can be so configured.
