[cds-amal]

On Windows, truffle compile will always recompile every contract.

versions

OS: Windows 11 (should fail on Windows 10 as well)

PS C:\Users\amal\dev\mc> truffle version
Truffle v5.4.32 (core: 5.4.32)
Solidity v0.5.16 (solc-js)
Node v16.13.1
Web3.js v1.5.3
PS C:\Users\amal\dev\mc>

Reproduction steps

• truffle unbox metacoin mc
• cd mc
• truffle compile
• truffle compile

You will notice truffle compiles every contract again.

instrumented output

Compare the output between Windows and Linux setting DEBUG=*,-compile:compilerSupplier

Linux (2nd compile)

$ DEBUG=*,-compile:compilerSupplier truffle compile
