Have an issue with "Unknown options" for web3j solidity generate

[Gelassen]

I am working on converting my contract.sol to contract.java by using web3j. Web3j has been installed by using

curl -L get.web3j.io | sh and web3j --version shows

Version: 1.4.1
Build timestamp: 2021-02-16 20:28:33.742 UTC 

Command to generate contract.java is:

web3j solidity generate -a swapvalue.abi -b swapvalue.bin -o . -p ru.home.swap where .abi and .bin were generated with help of Remix IDE.

The observed behavior is an error Unknown options: '-a', 'swapvalue.abi', '-b', 'swapvalue.bin', '-o', '.', '-p', 'ru.home.swap' with unclear reason as this is the same what docs and others users suggest.

What is the issue with this command?

The same for contract generated over truffle:

$web3j truffle generate ./build/contracts/SwapValue.json -o . -p ru.home.swap

Unmatched arguments from index 2: './build/contracts/SwapValue.json', '-o', '.', '-p', 'ru.home.swap' Did you mean: tests or truffle or solidity?

You can try "web3j generate solidity --abiFile xxx.abi --binFile xxx.bin -o .\src\main\java -p xxx"
