Update a build cache

Updates a build cache.

Checked 2026-09-28

This method is not served on the public API. api.sylphx.com does not route this call: its backend is not deployed behind the public API, or does not implement the call. This page documents the contract. It is kept out of the sidebar and of search engines.

Updates a build cache.

Not available yet. Sylphx Build is declared in the registry but no backend serves it: every call answers 501 with the problem code UNIMPLEMENTED.

Path PATCH https://api.sylphx.com/v1/orgs/acme/projects/shop/build_caches/build-cache
Scope build:write
Effect write — a successful call changes state.
Collection build_caches
Query update_mask, allow_missing, validate_only

#Request

Field	Type	What it is
`build_cache`	`BuildCache`	The build cache to update; `name` identifies it. Required.
`update_mask`	`field_mask`	The fields to write; unset writes every populated field.
`allow_missing`	`bool`	Create the Resource when it does not exist (declarative upsert).
`validate_only`	`bool`	Validate and return the result without writing anything.

#BuildCache

Field	Type	What it is
`name`	`string`	`orgs/{org}/projects/{project}/build_caches/{build_cache}`.
`meta`	`ResourceMeta`	Resource metadata.
`spec`	`BuildCacheSpec`	Desired state. Required.

#ResourceMeta

Field	Type	What it is
`labels`	`map<string, string>`	Caller-writable, indexed labels (AIP-122 label rules).
`annotations`	`map<string, string>`	Caller-writable, unindexed annotations.
`display_name`	`string`	Caller-writable human-readable name.

#BuildCacheSpec

Field	Type	What it is
`retention`	`duration`	Entries unused this long are evicted; default 7 days.

`reason`	`string`	A machine-readable UpperCamelCase reason.
`message`	`string`	A customer-safe human-readable message.
