If you want to build/package JET Hybrid application you must issue build:release or serve:release command. Read more about it in JET developer guide: Packaging Hybrid Mobile Applications. In order to run build:release or serve:release commands successfully, you need create buildConfig.json file, which includes information about self signed certificate. This allows to sign application and package it for release.
Steps below are tested for Android platform.
You can generate certificate with Java keytool utility. Navigate to Java home bin folder and run keytool. Specify correct path and preferred alias:
keytool -genkey -v -keystore /Users/andrejusbaranovskis/jdeveloper/mywork/jellyhouse-release-key.keystore -alias RedSamuraiConsulting -keyalg RSA -keysize 2048 -validity 10000
You will be asked to enter additional information, such as name, organization, location, etc.:
Once certificate is generated, you can create empty buildConfig.json file. I have created it in the root directory of JET Hybrid application. Certificate file is copied into the same location:
Provide release information in buildConfig.json. Since certificate file is located in the same folder, it is enough to specify its name without path. Include alias name, certificate password and keystore password:
If buildConfig.json contains correct entries, build:release should run successfully:
sudo grunt build:release --platform=android --buildConfig=buildConfig.json
Successful result output:
JET Hybrid release app built for Android platform size is 7.5 MB (major part takes Cordova libraries):
So, if you create self signed certificate and populate buildConfig.json correctly - it is very easy to run release build for Oracle JET Hybrid application.
