Useful commands

Running app (it also recompile your changes):

mvn spring-boot:run

Build app from scratch:

mvn clean install

R setup

To be able to use the prediction model in this project you need to have R environment set up.

First, you need to download and install the R itself. You can do that via this link: https://cloud.r-project.org/

Then you need to download and install couple additional packages:

1. https://cran.r-project.org/web/packages/Cubist/index.html
2. https://cran.r-project.org/web/packages/reshape2/index.html
3. https://cran.r-project.org/web/packages/plyr/index.html
4. https://cran.r-project.org/web/packages/rules/index.html
5. https://cran.r-project.org/web/packages/rio/index.html
6. https://cran.r-project.org/web/packages/zip/
7. https://cran.r-project.org/web/packages/openxlsx/

Depending on the platform you use you need to do it slightly differently, but it pretty much comes down to placing the downloaded decompressed file into the library director of R. For the server, there will a script auto installing this lovely mess (not implemented yet).
