SBT Compiler failure on trying to write to root directory ( missing build parameter?)

[Larry Mills-Gahl]

Hello,

I'm trying to track down an error in a project (a series of projects) that is causing an SBT compiler error 

on not having permission to create a directory. I'll give more detail below, but it sounds very much like

a base directory is not being set in the compiler so that it's trying to write to directories in the 

root of the computer. 

This didn't happen in Neon with plugin v 4.5, but it does happen in Oxygen with plugin v4.7

I'm hoping someone can point me toward the properties or environment variables that SBT uses to 

communicate the root of the buid structure to the plugin. 

Here are the relevant environments:

Eclipse  (SBT succeeds in this configuration )

Version: Neon.3 Release (4.6.3)

Build id: 20170314-1500

Scala Plugin 

Version: 4.5.0v-2_11-201612131030-0283a6

-- and -- 

Eclipse IDE for Java Developers (SBT fails on the project with the error below)

Version: Oxygen.3a Release (4.7.3a)

Build id: 20180405-1200

Scala Plugin

Version: 4.7.1v-2_12-201801021323-2dfe808

VAEO8 is the project and VAEO8/Libraries is where jar dependencies are found

This error shows it is failing when trying to write to the root of the computer. I tested this by 

creating the directory /VAEO8 (in the root of the computer) and giving myself

permission to write to it. THe compile succeeded then, but that's not a reasonable

workaround.
