aapt2 fails to run on the buildserver - AGP 8.12.0-alpha07 is latest compatible (#593) · Issues · F-Droid / admin · GitLab

Affected apps under this label: https://gitlab.com/fdroid/fdroiddata/-/merge_requests/?label_name%5B%5D=AGP-8.12.0 Between 8.12.0-alpha07 and 8.12.0-alpha08, aapt2 started to want a CPU that supports BMI1, CPUID, SSE4_1, SSSE3 ...

The reason is one build tool which now requires SSE4.1 instruction support to run.

Rant

This instruction is ancient. According to multiple people on HackerNews they’re still using Opteron servers! No wonder the builds take so long, a cheap NUC would be faster.
