Why can't I select my jarsigner in the editor settings?

I wanted to try out Android development in Godot. I followed the guide to word, yet the part when it says

“The jarsigner executable (from JDK 6 or 8) - On Windows, OpenJDK installs to a dir like %PROGRAMFILES%\ojdkbuild\java-1.8.0-openjdk-1.8.0.232-2\bin. On Linux, it typically installs to a dir like /usr/bin/jarsigner.”

I am on Linux, and so I went to the file path “/usr/bin/jarsigner”, and there was the jarsigner, but as strange as it sounds it’s the only file I cannot open. I could set the path for any other binary in that folder except for that.

I tried inputting the path (/usr/bin/jarsigner), but to no avail. Can somebody give a helping hand in this? What am I doing wrong?

Does it work if you enter /usr/bin in the FileDialog then manually select the jarsigner binary?

What Java version are you using? My path in the jarsigner setting field is this:

/usr/lib/jvm/java-13-openjdk/bin/jarsigner

My /usr/bin/jarsigner is a link:

/usr/bin/jarsigner -> /usr/lib/jvm/default/bin/jarsigner

You can check this with this command:

$ ls -l /usr/bin/jarsigner

The target does not exist. I have not cared to investigate why. I can build Android apps fine. If your situation is the same, try to find where the real jarsigner file is.

I am on Manjaro, an Arch Linux variant. So the situation might be different from yours.

I use the same distro, and did the same relink, issue persists.

Do not use the link, use the path to the real file that you check exists.

What is the full path to your jarsigner file?

I was stack with the same problem. I double check the java installation and everything was ok, other software was working like cordova, so I decided to try compiling Godot following this guide (https://docs.godotengine.org/es/stable/development/compiling/compiling_for_x11.html) and it was very easy.

Now the Godot’s file explorer shows all files inside /use/lib, and it looks has no problem with symbolic link files.
