如果sol版本编译超过0.7.1，就会出现上述问题，原因是因为 web3j会先从本地 C:\Users<User>.web3j\solc\release.json 获取最新的windows可用url，在 maven web3j 4.9.4 版本中，引入了子依赖 web3j-sokt 0.2.1, 在源代码 https://github.com/web3j/web3j-sokt/blob/release/0.2.1/src/main/kotlin/org/web3j/sokt/VersionResolver.kt 中可用看到 从 https://internal.services.web3labs.com/api/solidity/versions/ 下载了 release.json 文件，但是文件中从 0.7.1 之后windows_url一直为 “”， 所以无法找到合适的编译版本solc。

在 web3j-sokt 0.2.2 中 https://github.com/web3j/web3j-sokt/blob/release/0.2.2/src/main/kotlin/org/web3j/sokt/VersionResolver.kt ，release.json 的下载地址变更为 https://raw.githubusercontent.com/web3j/web3j-sokt/master/src/main/resources/releases.json ，截至目前文件内的最新可用版本为 solidity 0.8.13

所以我认为解决方案应该是 maven 排除 web3j-sokt 0.2.1， 引入新的 web3j-sokt 0.2.2.

You just have to mention in your solidity contract this line pragma solidity >=0.7.0 <0.9.0;.
This issue can be explained by the solidity version choose for your OS. It works fine on Windows for the 0.7.1 of solidity.
You can't use a recent version because of the solc-windows.zip instead of solc-windows.exe which changes the way it works.

I ran into a simillar problem. Go to C:\Users\<User>\.web3j\solc and check the releases.json file. There should be an entry with the desired solidity version. Check if a valid windows_url is provided. For me it wasn't so the plugin was not able to download the needed version as it does not know from where. You can manually download the desired version and place it alongside the other installed versions in C:\Users\<User>\.web3j\solc

KamilBemowskiGFT avatar KamilBemowskiGFT commented on July 19, 2024

It doesn't work, I'd like to use version 0.8.4 and I downloaded the version from this link: https://github.com/ethereum/solidity/releases/download/v0.8.4/solc-windows.exe and put that file to the directory C:\Users<User>.web3\solc\0.8.4 but still doesn't work with the same result. Do you have any idea?

已解决；
解决方案供参考:

  1. 下载插件源码，解压缩，导入IDEA ，修改 web3j-sokt 依赖版本。
  2. 执行 mvn clean install

最后刷新依赖项目maven仓库，即可。
