Bug report #21905
Functions of GRASS do not work in the Processing for QGIS 3.4.7/3.6.2... but work in the Processing for QGIS 3.4.7/3.6.2 with GRASS 7.6.1
|Affected QGIS version:||3.4.7||Regression?:||No|
|Operating System:||Windows||Easy fix?:||No|
|Pull Request or Patch supplied:||No||Resolution:||worksforme|
|Crashes QGIS or corrupts data:||No||Copied to github as #:||29720|
In Windows (installation OSGeo4W), We can't use GRASS in Processing when we launch the shortcut "QGIS Desktop 3.4.7" or "QGIS Desktop 3.6.2".... It's impossible to use any functions of GRASS (in processing) : r.reclass, r.mapcalc.simple, ...
=> The function return a message error with a bad path : "C:\OSGEO4~2\bin\bin" instead of "C:\OSGEO4~2\bin"...
when we launch the shortcuts "QGIS Desktop 3.4.7 with GRASS 7.6.1" or "QGIS Desktop 3.6.2 with GRASS 7.6.1". So we can use any functions of GRASS in processing without any problem. (See pic with r.mapcalc.simple)

I think it would be good if the error message does not say that it is missing a folder, rather it should indicate the use of QGIS with GRASS. This is because it is a new behavior. in QGIS 3.4.6, changing the name of the folder from grass76 to grass-7.6.1, (#21678) the error was "solved" and the grass commands could be used from QGIS (without) GRASS
So indicate that it is now mandatory to use QGIS with GRASS to use the grass modules, is a good idea.
