 如果构建 agent 使用 `root` 账户执行，缓存目录不应写死为 `/var/lib/jenkins`。推荐优先使用单独数据盘，例如 `/data/jenkins-cache/genarrative/`；如果没有数据盘，可使用 `/var/cache/genarrative-build/`：
 
 ```bash
-mkdir -p /var/cache/genarrative-build/{cargo-home,cargo-target,sccache}

+其中 `<component>` 使用 `api-server` 或 `stdb-module`。API 与 Stdb module 并行构建时不能共享同一个 `CARGO_HOME` 或 `CARGO_TARGET_DIR`，否则容易在 Cargo package cache 或 target 目录上出现 `Blocking waiting for file lock on package cache` 等锁等待。
