SolidityFunctionWrapperGenerator creates compile-time error for zero-argument constructor

[MaxBinnewies]

Hi Conor,

The following slightly modified example contract:

pragma solidity ^0.4.0;

contract SimpleStorage {
    uint storedData;
    
    function SimpleStorage() {
        storedData = 5;
    }

    function set(uint x) {
        storedData = x;
    }

    function get() constant returns (uint retVal) {
        return storedData;
    }
}

creates this Java code:

...
    public static Future<SimpleStorage> deploy(Web3j web3j, Credentials credentials, BigInteger initialValue) {
        return deployAsync(SimpleStorage.class, web3j, credentials, BINARY, encodedConstructor, initialValue);
    }
...

encodedConstructor cannot be resolved to a variable. This is due to the zero-argument constructor. When I add a fake(as in not used anywhere) uint argument to the constructor everything is fine. I do believe zero-argument constructors are allowed in Solidity, though.
I used the solidity web compiler to create .bin and .abi and am using web3j 1.0.3. I really like that SolidityFunctionWrapperGenerator now logs what its doing :-)

Best regards,
Max

This should be fixed by release v1.0.4.
Please reopen this ticket if not.

FYI - there are now unit tests for the code generator using a number of different compiled smart contracts.
