gradle - Hyperledger：使用 Gradle 构建链码
问题描述
使用 fabric-java-sdk 发送链码初始化请求时出现问题。
部署（安装）方法：
public Collection<ProposalResponse> deploy(Collection<Peer> peers)
throws InvalidArgumentException, ProposalException {
String chaincodeName = chaincode.name();
String chaincodeVersion = chaincode.version();
HyperLedgerClient hyperLedgerClient = hyperLedgerChannelClient.getHyperLedgerClient();
InstallProposalRequest request = hyperLedgerClient.newInstallProposalRequest();
ChaincodeID.Builder chaincodeIDBuilder =
ChaincodeID.newBuilder()
.setName(chaincodeName)
.setVersion(chaincodeVersion);
ChaincodeID chaincodeID = chaincodeIDBuilder.build();
LOGGER.info(
"Deploying chaincode " + chaincodeName + " using Fabric client " +
hyperLedgerClient.getUserContext().getMspId()
+ " " + hyperLedgerClient.getUserContext().getName()
);
request.setChaincodeID(chaincodeID);
request.setUserContext(hyperLedgerClient.getUserContext());
request.setChaincodeInputStream(chaincode.source());
request.setChaincodeVersion(chaincodeVersion);
request.setChaincodeLanguage(Type.JAVA);
return hyperLedgerClient.sendInstallProposal(request, peers);
}
初始化（实例化）方法：
public Collection<ProposalResponse> instantiate(
String functionName, String[] functionArgs)
throws InvalidArgumentException, ProposalException {
HyperLedgerClient hyperLedgerClient = hyperLedgerChannelClient.getHyperLedgerClient();
String channelName = hyperLedgerChannelClient.getName();
String chaincodeName = chaincode.name();
String userContextName = hyperLedgerClient.getUserContext().getName();
String mspId = hyperLedgerClient.getUserContext().getMspId();
LOGGER.info(
"Instantiate proposal request {} on channel {} with Fabric client {} {}",
chaincodeName, channelName, mspId, userContextName
);
InstantiateProposalRequest instantiateProposalRequest =
hyperLedgerClient.getHfClient().newInstantiationProposalRequest();
instantiateProposalRequest.setProposalWaitTime(180000);
ChaincodeID.Builder chaincodeIDBuilder = ChaincodeID.newBuilder()
.setName(chaincodeName)
.setVersion(chaincode.version());
ChaincodeID ccid = chaincodeIDBuilder.build();
LOGGER.info("Instantiating Chaincode ID {} on channel {}", chaincodeName, channelName);
instantiateProposalRequest.setChaincodeID(ccid);
instantiateProposalRequest.setChaincodeLanguage(Type.JAVA);
instantiateProposalRequest.setFcn(functionName);
instantiateProposalRequest.setArgs(functionArgs);
Map<String, byte[]> tm = new HashMap<>();
tm.put("HyperLedgerFabric", "InstantiateProposalRequest:JavaSDK".getBytes(UTF_8));
tm.put("method", "InstantiateProposalRequest".getBytes(UTF_8));
instantiateProposalRequest.setTransientMap(tm);
Collection<ProposalResponse> responses =
hyperLedgerChannelClient.sendInstantiationProposal(instantiateProposalRequest);
CompletableFuture<TransactionEvent> completableFuture =
hyperLedgerChannelClient.sendTransaction(responses);
LOGGER.info(
"Chaincode {} on channel {} instantiation {}",
chaincodeName, channelName, completableFuture
);
return responses;
}
chaincode.source() 指向 .tgz 文件，其内容如下

问题是我正在使用gradle. 如何让我的同伴使用 gradle？
解决方案
问题在于我正在发送tgz内部具有以下结构的存档：
src/main/...
build.gradle
settings.gradle
但我需要将其更改为：
src/src/main/...
src/build.gradle
src/settings.gradle
然后同行将识别 Gradle。
