How to properly import a .tmx file with the image used to create it?

I tried to create some maps with tield map, and the image I use to create this map(tielset texture) is stored in the desktop.
But after the map generation, I copied the file (map.tmx) and (texture.png) internal file (maps):

map = new TmxMapLoader () load ("maps / map.tmx");

but I still have this error even discounting that I did …
for the information I work with gradle. What do you think of this error?

Every idea will be appreciated.
