Suddenly I discovered web3j provides an option to auto-generate the Java contract from solidity contract. Sample case you can find here.
Unfortunately it does not recognize the import of openzeppelin contracts:
Error: Source "@openzeppelin/contracts/token/ERC721/ERC721.sol" not found: File not found. Searched the following locations: "".
--> SwapValue.sol:4:1:
|
4 | import "@openzeppelin/contracts/token/ERC721/ERC721.sol";
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Looks like openzeppelin provides an option to add its contracts to your projects:
npx oz link @openzeppelin/contracts-ethereum-package
, but it lives in a separate environment rather than web3j.
Is there a known option to combine the all of them into one project?
