AAB build shader compile failure on CI after upgrading from Axmol 2.5 (works locally & APK works)

[arungowda09]

I’m facing a shader compilation issue only when building AAB on CI after upgrading Axmol.

Axmol versions tested:

• 2.5 → works (CI + local)
• 2.7 / 2.9 / 2.10 → same issue

Environment details:

• Axmol versions: 2.5 (OK), 2.7 / 2.9 / 2.10 (issue)
• Platform: Android
• Local macOS build:
  • AAB ✅
• CI: Codemagic
  • APK ✅
  • AAB ❌ (black screen)

Build tools:

• NDK:
  • Local: r28
  • CI: r28

Error log (runtime):
:10738: DoCompileShader: Failed to compile shader
axmol:ERROR: Failed to compile shader, detail: Compile failed.
ERROR: Unexpected end of source found
1 compilation errors. No code generated.

Notes:

• Same project, same shaders
• No custom shader changes between versions
• CI APK works, CI AAB fails
• Local AAB works

Any guidance would be appreciated. Thanks!

Which CI system do you use?

[arungowda09]

I’m using Codemagic as the CI system.

Thanks! I’ll update to commit 795308c, test the AAB build on CI, and report back

[arungowda09]

Thanks a lot — the fix works on my side 👍
I tested it with axmol-2.10.0, and the AAB build on CI is now running correctly.

If possible could you share what was causing the shader issue in CI AAB builds?

The task execution order incorrect, just see the commit diff in build.gradle
