Can not generate a contract via $web3j generate solidity. Likely is know bug with external struct #1789

Closed Gelassen closed 1 year ago

_Bugtitle

Can not generate a contract via $web3j generate solidity with message

Generating com.example.wallet.contract.SwapValue ... Warning: Duplicate field(s) found: [FUNC_SAFETRANSFERFROM]. Please don't use names which will be the same in uppercase. not a valid name: struct Value

Likely it is #a known issue

Steps To Reproduce

  1. Take a contract
  2. Generate a contract abi and bin via hardhat compile
  3. Use command to generate java wrappers $web3j generate solidity -a SwapValue.abi -b SwapValue.bin -o . -p com.example.wallet.contract

Expected behavior

A contract java wrapper should appear in the root directory

Actual behavior

Message in console and there is no contract

Environment

Gelassen commented 1 year ago

@SweeXordious, could you please take a look? You had worked on similar issue, but a year later it is not in the release.

rach-id commented 1 year ago

Can you please try compiling the contract using solc and try again? Also, if you could share the bin and abi you have, would be awesome.

Gelassen commented 1 year ago

SwapValue.zip Here is existing .abi and .bin which had been extracted from .json generated over hardhat. I will work on solc compiler result in a minute.

Compiling over solc ($solc --bon SwapValue.sol) gives variety of errors linked to lack of imports:

A quick search shows several workarounds on this issue. A one of them is to add direct paths to the command:

$ --allow-path "/path/to/folderOne" --allow-path "/path/to/folderTwo"

, but it should not help with import to non local files like @openzeppelin/contracts/token/ERC721/ERC721.sol

Do you have any suggestion here?

rach-id commented 1 year ago

For these: 

@openzeppelin/contracts/token/ERC721/ERC721.sol

They should be downloaded locally and changing @openzeppelin to where the contracts are. I'll try doing it later today if I have time and come back to you

Gelassen commented 1 year ago

contract with local dependencies compiled over solc.zip I downloaded files to have them locally, changed paths to these local files and compile them via command $solc --abi --bin --optimize contracts/SwapValue.sol -o temp

Although running $web3j generate solidity command still returns the same issue with reference on invalid Value struct.

Checking official compiler docs only library import requires extra effort on final bytecode, the plain imports on local contracts should be compiled automatically.

Files added to this post if in case you need them.

A little bit more context regarding this issue. I came here when had faced with issue to run safeMint() on my contract (*). The balanceOf() call executes correctly, but safeMint() doesn't. Origin .sol contracts works well -- it was heavily tested locally over hardhat and this web service helped to verify it on Goerly testnet. There is no known issue with contract itself. The point is originally I implemented required by PoC logic manually as I had others issues with web3j java wrappers generators. When I faced with issue to run safeMint(), I made a list of possible bug causes where not correct implementation of java wrapper was one of them. That's why I have to return back to web3j java wrapper generator to confirm or exclude this possible root cause of the issue.

(*) the system returns error either 'Contract has been reverted' or "Transaction receipt was not generated after 600 seconds for transaction" when I doubled the gas passed with function.

Okey, so I was able to use the web3j-gradle-plugin to generate the wrapper:

The way I did was:

With the @openzeppelin folder containing the contracts downloaded from: https://www.npmjs.com/package/@openzeppelin/contracts

And I had the above wrapper.

This can be done is more elegant ways, but that is not the purpose of this issue. Let me know if this is what's needed.

Gelassen commented 1 year ago

Thank you, I am able to mint a token by using wrapper above. However there are variety of issues with web3g-cli new project command.

Thank you for your help with this. I will continue work on generating or writing java wrapper to make sure I am able to introduce new changes in any time with this version of library. Leave this issue opened or closed is up to you.

rach-id commented 1 year ago

it is not an android project, mixing web3j plugin with the rest android plugins gives a compile error

even when generating a kotlin project?

I had an issue to build hello world project, the root cause issue would require more investigation

can you share some logs?

the origin post's root cause issue is not clear and would take more efforts to figure it out.

That one needs a bit more work to support generating projects for a set of contracts, and not only one.

Gelassen commented 1 year ago

I am able to create hello world project via command $web3j new HelloWorld in isolated environment in VM. The root cause was incompatibility issue between modern Java (jdk-16 has been installed) and gradle version used by web3j-cli (gradle-5.6). 

it is not an android project, mixing web3j plugin with the rest android plugins gives a compile error

even when generating a kotlin project?

The issue appears when I add id 'org.web3j' version '4.8.4'. It is common piece of code for java and kotlin versions of web3j newly started projects. A whole list of plugin for this module is: 

plugins {
    id("com.android.library")
    id("org.jetbrains.kotlin.android")
    id("org.web3j") version "4.8.4"
}

IMO, you have to add in web3j docs the disclaimer at this stage the library does not support contracts which imports others contracts under the hood.

rach-id commented 1 year ago

jdk-16 is not supported. That's why it's giving you the issue. Go for jdk-11 or 1.8. Other versions also might be supported, but I didn't check that for some time now.

For android project, I have the following build.gradle which was generated using web3j new --kotlin :

plugins {
    id 'java'
    id 'org.jetbrains.kotlin.jvm' version '1.3.61'
    id 'application'
    id "com.github.johnrengelman.shadow" version "5.2.0"
    id 'org.web3j' version '4.8.4'
}

group 'org.web3j'
version '0.1.0'

sourceCompatibility = 11

repositories {
    mavenCentral()
    jcenter()
}

web3j {
    generatedPackageName = 'org.web3j.generated.contracts'
    excludedContracts = ['Mortal']
}

ext {
    web3jVersion = '4.8.4'
    logbackVersion = '1.2.3'
}

dependencies {
    implementation "org.web3j:core:$web3jVersion",
            "ch.qos.logback:logback-core:$logbackVersion",
            "ch.qos.logback:logback-classic:$logbackVersion"
    implementation("org.web3j:web3j-unit:$web3jVersion")
    implementation("org.web3j:web3j-evm:$web3jVersion")
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8"
    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.3.1'
    testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.3.1'
}

jar {
    manifest {
        attributes(
                'Main-Class': 'org.web3j.Web3App',
                'Multi-Release':'true'
        )
    }
}
application {
    mainClassName = 'org.web3j.Web3App'
}

test {
    useJUnitPlatform()
}

compileKotlin {
    kotlinOptions.jvmTarget = "11"
}

compileTestKotlin {
    kotlinOptions.jvmTarget = "11"
}

which should work for android.

IMO, you have to add in web3j docs the disclaimer at this stage the library does not support contracts which imports others contracts under the hood.

It does support them, using the web3j-gradle-plugin. It even downloads some classic libraries for you. Except that the support is still a bit not thaaat user-friendly. It needs more work on that. I used the web3j-gradle-plugin to generate the above wrapper. Also, for projects, you can import them straight up using web3j import --kotlin -s <path to solidity file/folder>. Except, that it needs a bit of gymnastics to work correctly. The functionality is there, tho.

For the issue, if you're able to close it yourself, please do. I don't have those permissions at the moment. Thanks

Gelassen commented 1 year ago

I do not want to sound critical - thank you for all your efforts on writing this - my aim is to make it work on my side at minimum and at most - contribute to library readiness as a mature product.

This is a default gradle config file generate by Android Studio: 

plugins {
    id 'com.android.application'
    id 'org.jetbrains.kotlin.android'
    // id 'org.web3j' version '4.8.4'
}

android {
    compileSdk 32

    defaultConfig {
        applicationId "com.example.web3jplugintest"
        minSdk 21
        targetSdk 32
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = '1.8'
    }
}

dependencies {

    implementation 'androidx.core:core-ktx:1.7.0'
    implementation 'androidx.appcompat:appcompat:1.5.1'
    implementation 'com.google.android.material:material:1.6.1'
    implementation 'androidx.constraintlayout:constraintlayout:2.1.4'
    testImplementation 'junit:junit:4.13.2'
    androidTestImplementation 'androidx.test.ext:junit:1.1.3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
}

Adding web3j plugin to this script leads to compile error. This dsl config file is some standard we have to follow.

Anyway, it is a secondary issue. Regarding the primary issue I just finished experiment with approach suggested above and still get unknown struct Value and unknown struct Match (the Match is used in another contract SwapChain.sol). It is the same issue the topic is started. (note: it is done VM's fresh installed Ubuntu server)

I will try to put my struct inside the contract to see if web3j would be able generate wrapper in this case.

Also please note EVmVersion file lacks the latest evm such as 'London' it would be good to extend it.

rach-id commented 1 year ago

Got you :+1:

Also please note EVmVersion file lacks the latest evm such as 'London' it would be good to extend it.

Please create an issue for this in https://github.com/web3j/solidity-gradle-plugin and hopefully someone picks it up.

I am no longer actively contributing to the library as I have other stuff on my plate now. However, if you see some ways of improvements to the general usability, it would be awesome if you could open relevant issues/PRs and I will be glad to approve them.

Closing this, as the issue is now being addressed in solidity-gradle-plugin
