How to build java chaincode behind proxy

Question

Does anyone know how to build java chaincode behind proxy? On instantiating a java chaincode behind proxy I'm getting the following error.

Error: could not assemble transaction, err proposal response was not successful, error code 500, msg error starting container: error starting container: Failed to generate platform-specific docker build: Error returned from build: 1 "Gradle build

I'm using sample chaincode (fabirc-samples/chaincode/chaincode-example02/java)

You seem to be having basic connectivity issues with Maven itself rather than anything related to chaincode itself. Can you access https://repo.maven.apache.org at all? — Roddy of the Frozen Peas, Sep 06 '19 at 01:23
@RoddyoftheFrozenPeas It seems I can access repo.maven.apache.org ` $ curl -x http://proxy.company.com:8080 repo.maven.apache.org Index of /

I solved the problem by myself.
The solution is building image that has proxy setting like below one before instantiating chaincode.

FROM hyperledger/fabric-javaenv

ENV JAVA_OPTS "-Dhttps.proxyPort=8080 -Dhttps.proxyHost=your.proxy.com - Dhttp.proxyPort=8080 -Dhttp.proxyHost=your.proxy.com"
