All day I was struggling with QGIS 18 and GRASS 7. My mission was simple: import a file in QGIS 2.18, run v.clean and then go home. Unfortunately it turned out that my mission was not that easy.
First of all, although I read everywhere that GRASS is now a component of QGIS 2.18, when I tried running the plugins, received an error telling me that I needed to configure the working directory for GRASS.
I tried different things (see the list below) doing that and I failed many times.
Installing GRASS 7 separately and moving the contents of the folder in the apps subfolder of QGIS, in order to be able to point it in the program
Found out that there already was a grass installation in my QGIS folder. Linked the application to that folder
Read what was written in the QGIS documentation about configuring grass, followed the steps, failed.
Installed MSYS, linked the folder to the corresponding one in QGIS (heard that GRASS 7 did not require MSYS)
Started the GUI of the software, got an error while trying to import the shapefile, a module (forgot the name) was missing and the command failed.
Can anyone guide me step-by-step on how I can configure the software in order to work properly?
Thinking as a last resort downgrading to QGIS 2.14 and hoping for the best.
