June 2025 — JetBrainsRuntime: Windows AArch64 DevKit Host Architecture Detection and Conditional Toolchains Key features delivered: - Implemented host architecture detection in the Windows AArch64 DevKit creation script to distinguish x64 vs aarch64 hosts and select the correct toolchain. - Added conditional copying of ARM64 binaries based on detected host architecture. - Improved CLI output with clear messaging on supported platforms and the steps to follow during DevKit creation. Bug fixes: - Fixed Windows AArch64 DevKit Creation flow to reliably detect host architecture and copy the appropriate binaries. This is tied to commit 6d05a1d3f492b6f06b603ae2bb0d03dfb6c8b8f2 (8357079: Fix Windows AArch64 DevKit Creation). Overall impact and accomplishments: - More reliable DevKit builds across Windows hosts (x64 and aarch64), reducing setup time and troubleshooting. - Enhanced cross-architecture support that accelerates onboarding and reduces support overhead. Technologies/skills demonstrated: - Scripting/automation for cross-platform DevKit setup, host-architecture detection, and toolchain selection. - Conditional logic, robust CLI UX improvements, and ARM64/x64 binary management. Business value: - Increased developer productivity through reliable, automated DevKit creation. - Lower maintenance costs due to fewer build failures and support tickets.
