Fail to export Android release when any of (but not all) debug keystore environment variables are set

[Nestastnikos]

Tested versions

Reproducible in: 4.5-beta5 4.4.1 stable, 4.3 stable
Untestable at: 4.0.0 stable (The scenario cannot be tested, because there is already an error in the editor in the export popup missing configuration for debug keystore.)

System information

Arch Linux SMP PREEMPT_DYNAMIC Sat, 02 Aug 2025 01:20:06 +0000 - Wayland - Vulkan (Forward+) - dedicated AMD Radeon RX 570 Series (RADV POLARIS10) - Intel(R) Core(TM) i5-7600K CPU @ 3.80GHz (4 Threads)

Issue description

When attempting to export a Godot project to Android in release mode, the export process erroneously fails if any debug keystore-related environment variables (GODOT_ANDROID_KEYSTORE_DEBUG_USER, GODOT_ANDROID_KEYSTORE_DEBUG_PASSWORD, GODOT_ANDROID_KEYSTORE_DEBUG_PATH) are set.

The specific error message received is:
ERROR: Cannot export project with preset "android" due to configuration errors: Either Debug Keystore, Debug User AND Debug Password settings must be configured OR none of them.

export.log

This behavior is undesirable because, during a release mode export, the presence or absence of debug keystore configurations or associated environment variables should be entirely irrelevant to the export. The release build should exclusively rely on the specified release keystore settings. The current implementation incorrectly validates debug keystore information even when it is not applicable to the requested export mode, thus preventing successful release builds under these circumstances.

Steps to reproduce

1. Execute the export command, ensuring godot is in your system's PATH:

env GODOT_ANDROID_KEYSTORE_DEBUG_USER=androiddebugkey godot --headless --verbose --export-release android "./output.apk"

Note: The env command temporarily sets the GODOT_ANDROID_KEYSTORE_DEBUG_USER environment variable for the duration of this command, simulating a scenario where debug keystore variables are present in the environment.

Actual result: Error due to missing information relevant to debug keystore.
Expected result: Error due to missing information relevant to release keystore.

Can you reproduce this with Godot 4.4.1 and 4.5-beta5?

Yes, the problem persists.

I tested the same scenario with Godot versions 4.1.1 stable 4.5-beta5, I made sure to download the corresponding export template for each version.

I tried to test it even with 4.0.0 stable, but at that version it was untestable, because the error about missing debug keystore information is present in the editor export popup and export cannot even be run.

EDIT: I made it work with 4.0.0 stable, the export process itself in that version could finish successfully. It worked with this setup

• I supplied valid release keystore path, user and password.
• I supplied path to the debug keystore file.
• Debug keystore user and password remained empty.

To summarize, the nature of the problem in 4.0.0 stable is different, comparing to my original issue. If path to the debug keystore is not supplied, the export cannot even be run. But once valid debug keystore path is provided, the export itself runs successfully, even if user and password for debug keystore is not provided.
