Thunar doesn't allow setting executable bit on files it does not recognize as executable.

[Carsten Holzmüller]

I can't set the execution right for *.jar files in thunar. It works for *.sh files.

I confirm the problem. A similar error. To solve had to add in the "Configure custom actions" item "chmod +x %F".

Thunar uses the system mimetypes to try to determine if a file is an executable type (program binaries, shell scripts etc). If the file is not in the list then the executable bit property will not be shown in properties. This is a design decision so you'd need to take it up with Xfce upstream.

Here's the exact bit of code that does this: http://git.xfce.org/xfce/thunar/tree/thunar/thunar-permissions-chooser.c#n1008

I am not into stuff such as Minecraft, but not having it on a right click is a pity...

I work in a NGO giving computers running under GNU/Linux and most of the people never use a terminal.

GUI has improved a lot. One of the reason of a bad reputation of Linux, that' it was just for geeks and that you have to use a terminal all the time... Nowadays, it's a legend for the common tasks. Another bad reputation Linux had was about playing games. It greatly improved, but there are still a lot of games you have to download from the websites with a jar extension.

Nautilus can with a right click / permission be marked as an executable. I prefer Thunar and don't understand why it is not possible.
Here is my opinion ;)

Anyway, thanks to all the devs working on Thunar, you do a great job !
