forge build
Build the project's smart contracts
$ forge build --help
Usage: forge build [OPTIONS] [PATHS]...
Options:
-h, --help
Print help (see a summary with '-h')
-j, --threads <THREADS>
Number of threads to use. Specifying 0 defaults to the number of
logical cores
[aliases: --jobs]
Build options:
--names
Print compiled contract names
--sizes
Print compiled contract sizes. Constructor argument length is not
included in the calculation of initcode size
--ignore-eip-3860
Ignore initcode contract bytecode size limit introduced by EIP-3860
--no-cache
Disable the cache
--dynamic-test-linking
Enable dynamic test linking
--skip <SKIP>...
Skip building files whose names contain the given filter.
`test` and `script` are aliases for `.t.sol` and `.s.sol`.
[PATHS]...
Build source files from specified paths
Cache options:
--force
Clear the cache and artifacts folder and recompile
Linker options:
--libraries <LIBRARIES>
Set pre-linked libraries
[env: DAPP_LIBRARIES=]
Compiler options:
--ignored-error-codes <ERROR_CODES>
Ignore solc warnings by error code
-D, --deny <LEVEL>
A compiler error will be triggered at the specified diagnostic level.
Replaces the deprecated `--deny-warnings` flag.
Possible values: - `never`: Do not treat any diagnostics as errors. -
`warnings`: Treat warnings as errors. - `notes`: Treat both, warnings
and notes, as errors.
Possible values:
- never: Always exit with zero code
- warnings: Exit with a non-zero code if any warnings are found
- notes: Exit with a non-zero code if any notes or warnings are
found
--no-auto-detect
Do not auto-detect the `solc` version
--use <SOLC_VERSION>
Specify the solc version, or a path to a local solc, to build with.
Valid values are in the format `x.y.z`, `solc:x.y.z` or
`path/to/solc`.
--offline
Do not access the network.
Missing solc versions will not be installed.
--via-ir
Use the Yul intermediate representation compilation pipeline
--use-literal-content
Changes compilation to only use literal content and not URLs
--no-metadata
Do not append any metadata to the bytecode.
This is equivalent to setting `bytecode_hash` to `none` and
`cbor_metadata` to `false`.
--ast
Includes the AST as JSON in the compiler output
--evm-version <VERSION>
The target EVM version
--optimize [<OPTIMIZE>]
Activate the Solidity optimizer
[possible values: true, false]
--optimizer-runs <RUNS>
The number of runs specifies roughly how often each opcode of the
deployed code will be executed across the life-time of the contract.
This means it is a trade-off parameter between code size (deploy cost)
and code execution cost (cost after deployment). An `optimizer_runs`
parameter of `1` will produce short but expensive code. In contrast, a
larger `optimizer_runs` parameter will produce longer but more gas
efficient code
--extra-output <SELECTOR>...
Extra output to include in the contract's artifact.
Example keys: evm.assembly, ewasm, ir, irOptimized, metadata
For a full description, see
[https://docs.soliditylang.org/en/v0.8.13/using-the-compiler.html#input-description](https://docs.soliditylang.org/en/v0.8.13/using-the-compiler.html#input-description)
--extra-output-files <SELECTOR>...
Extra output to write to separate files.
Valid values: metadata, ir, irOptimized, ewasm, evm.assembly
Project options:
-o, --out <PATH>
The path to the contract artifacts folder
--revert-strings <REVERT>
Revert string configuration.
Possible values are "default", "strip" (remove), "debug"
(Solidity-generated revert strings) and "verboseDebug"
--build-info
Generate build info files
--build-info-path <PATH>
Output path to directory that build info files will be written to
--root <PATH>
The project's root path.
By default root of the Git repository, if in one, or the current
working directory.
-C, --contracts <PATH>
The contracts source directory
-R, --remappings <REMAPPINGS>
The project's remappings
--remappings-env <ENV>
The project's remappings from the environment
--cache-path <PATH>
The path to the compiler cache
--lib-paths <PATH>
The path to the library folder
--hardhat
Use the Hardhat-style project layout.
This is the same as using: `--contracts contracts --lib-paths
node_modules`.
[aliases: --hh]
--config-path <FILE>
Path to the config file
Watch options:
-w, --watch [<PATH>...]
Watch the given files or directories for changes.
If no paths are provided, the source and test directories of the
project are watched.
--no-restart
Do not restart the command while it's still running
--run-all
Explicitly re-run all tests when a change is made.
By default, only the tests of the last modified test file are
executed.
--rerun-failed
Re-run only previously failed tests first when a change is made.
If all previously failed tests pass, the full test suite will be run
automatically. This is particularly useful for TDD workflows where you
want fast feedback on failures.
--watch-delay <DELAY>
File update debounce delay.
During the delay, incoming change events are accumulated and only once
the delay has passed, is an action taken. Note that this does not mean
a command will be started: if --no-restart is given and a command is
already running, the outcome of the action will be to do nothing.
Defaults to 50ms. Parses as decimal seconds by default, but using an
integer with the `ms` suffix may be more convenient.
When using --poll mode, you'll want a larger duration, or risk
overloading disk I/O.
Display options:
--color <COLOR>
The color of the log messages
Possible values:
- auto: Intelligently guess whether to use color output (default)
- always: Force color output
- never: Force disable color output
--json
Format log messages as JSON
--md
Format log messages as Markdown
-q, --quiet
Do not print log messages
-v, --verbosity...
Verbosity level of the log messages.
Pass multiple times to increase the verbosity (e.g. -v, -vv, -vvv).
Depending on the context the verbosity levels have different meanings.
For example, the verbosity levels of the EVM are:
- 2 (-vv): Print logs for all tests.
- 3 (-vvv): Print execution traces for failing tests.
- 4 (-vvvv): Print execution traces for all tests, and setup traces
for failing tests.
- 5 (-vvvvv): Print execution and setup traces for all tests,
including storage changes.
