| Build the APK with buck2, from pins rather than from a second checkout a71ef8f nandi 19d ago | 1 | # The stock prelude//platforms:default with its cache switches flipped on. |
| 2 | # |
| 3 | # The prelude's own `execution_platform` rule is static Starlark — there is no |
| 4 | # buckconfig key that turns caching on for it — so the rule is copied here and |
| 5 | # its CommandExecutorConfig changed. Everything else mirrors the original |
| 6 | # exactly, so this platform stays configuration-identical to the default. |
| 7 | # |
| 8 | # Whether actions may run on a worker is an attribute now rather than a |
| 9 | # constant. It was false because it had to be: the toolchain named absolute |
| 10 | # paths inside this checkout, which no worker would have. Both compilers are |
| 11 | # dependencies now, so there is something to ship. |
