Solidity compiler binaries, packed into jar for use in Java based projects.
Jars are available at: https://bintray.com/ethereum/maven/org.ethereum.solcJ-all/
Can be included in gradle via:
compile 'org.ethereum:solcJ-all:0.4.23'
We use jar in EthereumJ project, where we add addition layer of classes to interact with solc:
And then we use code snippet for compilation:
String contractSrc =
"pragma solidity ^0.4.23;\n" +
"contract a {" +
" function() {throw;}" +
"}";
SolidityCompiler.Result res = SolidityCompiler.compile(
contractSrc.getBytes(), true, ABI, BIN, INTERFACE, METADATA);
System.out.println("Out: '" + res.output + "'");
System.out.println("Err: '" + res.errors + "'");
CompilationResult result = CompilationResult.parse(res.output);
CompilationResult.ContractMetadata a = result.contracts.get("a");
CallTransaction.Contract contract = new CallTransaction.Contract(a.abi);
System.out.printf(contract.functions[0].toString());
