[solana-client] [2.0.1] - Multiple build errors

[Jamesmallon1]

Problem

Rust Version: 1.79.0
IDE: Rust Rover
Affected Crate: solana-client
Affected Crate Version: 2.0.1

Solana Client fails to build due to a dependency issue with spl-token-2022 v3.0.2.
It appears that this dependency has been left behind and is currently breaking the application.

Reproducible Cargo File:

[package]
name = "networking"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
tokio = { version = "1.37.0", features = ["full"] }
tokio-tungstenite = { version = "0.21.0", features = ["native-tls"] }
serde = { version = "1.0.203", features = ["derive"] }
serde_json = "1.0.117"
futures-util = { version = "0.3.30" }
solana-client = "2.0.1"
async-trait = "0.1.80"
log = "0.4.21"
reqwest = { version = "0.12.4", features = ['json'] }
serde_urlencoded = "0.7.1"
rust_decimal = "1.35.0"

Proposed Solution

Bring solana-client up to speed with the rest of the upgraded crates.

[joncinque]

The crates are all up to speed, but most likely your Cargo.lock is using two different versions of solana-program. You can either edit the lockfile by hand to remove entries of solana-program 1.18.X, or clear your lockfile and regenerate it with updated dependencies.

If you create a new project with the Cargo.toml you've provided, the build will actually succeed!
