Bintray Repository Shutdown

[ghareeb-falazi]

I am unable to use the plugin, since it cannot access the Bintray repository (mentioned in https://github.com/web3j/web3j-maven-plugin/blob/master/pom.xml). I am receiving the following error in maven:

Error:  Failed to execute goal org.web3j:web3j-maven-plugin:4.2.0:generate-sources (generate-sources) on project 
org.eclipse.winery.accountability: Execution generate-sources of goal org.web3j:web3j-maven-plugin:4.2.0:generate-sources

(I know the plugin version I have is old, but I don't think the error relates to that) I found this notification that the Bintray is shutting down in May 2021 altogether: https://lists.boost.org/Archives/boost/2021/02/250813.php

I just noticed that the Bintray repo is probably referenced only because of the solcJ dependency (which seems to be removed in recent versions). Perhaps, the reference to Bintray repo should simply be removed from the pom file.

Hi , please let me know how you have fixed this issue i am also getting same issue.

I solved it by using a newer version of the plugin that does not depend on the SolcJ compiler implementation. I.e., bump up the <web3j-maven-plugin.version>4.2.0</web3j-maven-plugin.version> to e.g., 4.6.5

[rkomaturi2382]

hi , thanks , i have changed it to 4.8.2 and now its working fine .However i am facing new issue deploy method is not available

The method deploy(Class<T>, Web3j, Credentials, ContractGasProvider, String, String, BigInteger) from the type Contract is not visible

MyContract.deploy(MyContract.class,quorumConnection.getWeb3(),
			  quorumConnection.getCredentials(),new
			  DefaultGasProvider(),MyContract.BINARY,
			  "first contract" ,BigInteger.valueOf(0));

i dont see any examples with latest version of web3j.

I have the same issue, I switched to 4.8.2 version then it worked.
