failed to declare contract which is compiled by "Scarb"

[Ljiacheng]

I build a contract which is compiled by Scarb. And I get a file named "hello_HelloStarknet.sierra.json" with command scarb --release build for example.
When I use command starknet declare --contract target/release/hello_HelloStarknet.sierra.json, I get this error:

scarb version:

scarb 0.2.0-alpha.2 (f9c07ce68 2023-05-05)
cairo: 1.0.0-rc0 (https://crates.io/crates/cairo-lang-compiler/1.0.0-rc0)

starknet version:

starknet 0.11.0.2

By the way, with a file tree:

.
├── Scarb.toml
├── cairo_project.toml
└── src
    ├── hello_starknet.cairo
    ├── interface.cairo
    └── lib.cairo

I don't known how to build a [contract].json file with "starknet-compile"

You can follow these steps to pull a more recent version of the cairo package which includes the compiler but use 1003d5d14c09191bbfb64ee318d1975584b3c819 instead of the documented commit sha.

Don't forget to apply the troubleshooting section as needed.
