Oasis-compile is a truffle compiler extension used to compile both Solidity and Rust contracts with or without confidentiality. It is expected to run within the context of the Oasis Contract-Kit, particularly for the use of compiling Rust contracts.

oasis-compile [command?] 

• default compiles all Solidity and Rust contracts in contracts/ outputing artifacts to .oasis-build/.
• clean removes all compiled output from truffle and oasis-compile.

To ensure your contracts are properly compiled, place them in the contracts/ directory, relative to the root of your truffle project. For Rust, this includes your contract crate.

To compile your contracts with confidentiality, prepending the Oasis deploy header to a contract's bytecode, name either your solidity contract or rust crate directory of the form confidential_* or confidential-*. For example, confidential_MyContract.sol or confidential-my-rust-contract.

To integrate this into your truffle project, npm install the package and add the following to your truffle-config.js:

compilers: { external: { command: "./node_modules/.bin/oasis-compile", targets: [{ path: "./.oasis-build/*.json" }] } }
