Issues generating Java proxies from external Truffle project #1521

_Issuetitle

Generate Java proxies from external Truffle project

_Issuedescription

I have a truffle project that has a contract that extends OpenZeppelin's ERC1155. (Which I deploy to Ganache)

        pragma solidity ^0.8.0;

        import "../node_modules/@openzeppelin/contracts/token/ERC1155/ERC1155.sol";
        import "../node_modules/@openzeppelin/contracts/access/Ownable.sol";

        contract Items is ERC1155, Ownable {

            mapping(uint256 => bool) tokenIdMinted;

            constructor() ERC1155("http://localhost:8080/api/token-metadata/{id}") {

            }

            function mintCoupon(address owner, uint256 tokenId, uint256 amount)
                public onlyOwner
            {
                require(!tokenIdMinted[tokenId], "This token id was already minted");
                tokenIdMinted[tokenId] = true;
                _mint(owner, tokenId, amount, "");

            }
        }

Meanwhile I have a Java maven project where I want to interact with Ganache and the smart contract. So far I have connected to Ganache using web3j and am able to read account balances etc.

Next I need to lookup the contract on the Java side with web3j and call my custom mintCoupon function. To so this I believe I need to generate Java proxies from the .sol files. I was hoping I could do this by referencing them in the web3j plugin (unless I can point them to json abi files instead?):

<plugin>
                <groupId>org.web3j</groupId>
                <artifactId>web3j-maven-plugin</artifactId>
                <version>4.8.7</version>
                <configuration>
                    <soliditySourceFiles>
                        <directory>/Users/Emmett/dev/walsingh/seol/blockchain/ethereum/learn/</directory>
                        <includes>

                            <include>contracts/Items.sol</include>

                        </includes>
                    </soliditySourceFiles>
                    <outputFormat>java</outputFormat>
                </configuration>
            </plugin>

Anyway, when I run the maven plugin I get the following issues:

not sure I follow.. how should I fix ?

This sounds like a problem related to web3j-maven-plugin rather than webj. The error (A type incompatibility occurred ...: class org.json.simple.JSONArray cannot be cast to class java.lang.String) is the same one reported at https://github.com/web3j/web3j-maven-plugin/issues/83 and his fork (longdt/web3j-maven-plugin) fixed it for me.
