PoCo Java wrappers for the iExec platform

Steps to generate Java Wrappers for Smart Contracts

First you need to install last version of Web3j CLI, the simplest way to install the Web3j CLI is via the following script:

curl -L get.web3j.io | sh && source ~/.web3j/source.sh

Verify the installation was successful

web3j -v 
Version: 1.4.2

After, you need to clone Poco repository

git clone https://github.com/iExecBlockchainComputing/PoCo/
cd PoCo
git checkout x.y.z

Edit script generateContractWrappers and check lines 15 and 18. If necessary, adjust the directories to match your local work tree.

#Put here the PoCo-dev directory that contains smart contracts (JSON files)
POCO_DEV_CONTRACTS_DIRECTORY=${HOME}/iexecdev/PoCo/build/contracts/

#Put here the src/main/java/ directory of commons-poco project
COMMONS_POCO_WRAPPER_DIRECTORY=${HOME}/iexecdev/iexec-commons-poco/src/main/java/

You can now run the script

./generateContractWrappers IexecInterfaceTokenABILegacy

After this execution and if no error has occurred, you must rename IexecInterfaceTokenABILegacy.java to IexecHubContract.java and also rename the java class.
