If your system doesn't have fonts installed, and you're running programs which need them, like Jenkins, the best solution is to update `$JAVA_HOME/lib` folder and add a file named `fontconfig.properties`.
You can copy the contents from this file < (remember to remove the .src extension when copying).
Then, on relevant entries like:
filename.Arial=ARIAL.TTF
filename.Arial_Bold=ARIALBD.TTF
filename.Arial_Italic=ARIALI.TTF
filename.Arial_Bold_Italic=ARIALBI.TTF
Just change them to something like
filename.Arial=/home/frankie/fonts/Arial.ttf
filename.Arial_Bold=/home/frankie/fonts/ArialBold.ttf
filename.Arial_Italic=/home/frankie/fonts/ArialItalic.ttf
filename.Arial_Bold_Italic=/home/frankie/fonts/ArialBoldItalic.ttf
And you're all set!
