Importar proyectos de años anteriores

Due to internal GradleRIO changes, it is necessary to update projects from previous years. After Installing WPILib for 2026, any 2025 projects must be imported to be compatible.

Cambios importantes (Java/C++)

Nota

The WPILib team is heavily working on the 2027 Systemcore control system, and thus there are less changes for 2026 then in previous years.

Sistemas operativos y arquitecturas compatibles:

  • Windows 10 y 11, solo de 64 bits. No son compatibles 32 bits y Arm.

  • Ubuntu 22.04 & 24.04, 64 bit. Otras distribuciones de Linux con glibc >= 2.34 pueden funcionar, pero no tienen soporte

  • macOS 13.3 o superior, tanto Intel como Arm.

Advertencia

Los siguientes sistemas operativos ya no tendrán soporte: macOS 12 o anteriores, Ubuntu 18.04 & 20.04, Windows 7, Windows 8.1, y cualquier 32-bit Windows.

Nota

Windows 10 support from Microsoft ended in October 2025. We intend to continue supporting Windows 10 through the 2026 season, but may have to drop support in 2027. Teams should start planning their upgrade path to Windows 11.
