Error: Temporary file value is not set

I want to build an apk with github actions .

My project : https://github.com/poorvajappja/gluon-sample-ci

But if I run workflow it comes like this .

How can I solve this error ?

I have exactly the same problem. The Gluon instructions seem not to include a description on what needs to be done for a clean machine/user to establish the code signing necessary for the test gluon-sample-ci to complete building for Android or iOS

@MichaelEllis I can't understand. Can you explain in detail ?

I have made some progress but have now been stumped by the necessary steps required to gain the necessary signing certificates for Apple which require I pay for Apple developer fee. This is going to have to wait for a bit!

I am stuck with the same error with the Android build using ubuntu-lastest runner as well as a self hosted runner using ubuntu 22.04 running in a Virtual Box session on a Windows host. I have been able to build the project successfully using maven on the Virtual box session so I am leaning towards a regression in a tool used in the yaml script as a cause.

This error building for Android resolved for me on a self-hosted runner after I built a keystore using Android Studio and converted it to base64 supplied as a base64 entry in github action secrets.

Code snippet to convert to base 64
new String(java.util.Base64.getEncoder().encode(java.nio.file.Files.readAllBytes(java.nio.file.Paths.get("mykey.jks"))))

Would it be possible to either check for the keystore and issue an appropriate error or default to creating a debug keystore. That might make for a faster startup process for new users.

I think making use of CI as Github actions is very big step in making JavaFX viable on cell phones and embedded projects like the Raspberry Pi. Getting the full tool chain working on the various platform and keeping the various components working has become a major pain with the pace of updates to Java, Eclipse and or IntelliJ, Android, Linux, Graal and Visual Studio, Raspian etc.

Ci as actions on Github doesn't simplify the process but it does centralize it!
