This submodule generates the GCN CLI application which is compiled to a native executable gcn, which works similarly to the Micronaut mn CLI with the addition of being able to generate GCN applications by specifying clouds and services.
The main class is GcnStarter which defines the "core" command and the 3 subcommands "create-app" (GcnCreateAppCommand), "create-function" (GcnCreateFunctionCommand), and "create-gateway-function" (GcnCreateGatewayFunctionCommand).
When you run the application and provide valid arguments, the ProjectGenerator bean (GcnProjectGenerator) creates the applications or functions. These are generated as a multi-module project with the core library "lib" and one module for each selected cloud.
There are a few ways to generate a project.
-
Run
./gradlew clean assemblefrom the project root to build the jars in each submodule’sbuild/libsdirectory. Then runjava -jar path/to/gcn/gcn-cli/build/libs/gcn-cli-<VERSION>-all.jar create-app com.example.demo --services=… --clouds=… --features=…passing any features and clouds or other args -
Run
./gradlew clean :gcn-cli:nativeCompilefrom the project root to build a native executable inbuild/native/nativeCompile, then runpath/to/gcn/gcn-cli/build/native/nativeCompile/gcn create-app com.example.demo --services=… --clouds=… --features=…passing any features and clouds or other args -
Run in IntelliJ by creating a Micronaut run configuration with
Main classcloud.graal.gcn.GcnStarter. Set theWorking directoryto the location where you want to generate the project, and specify the command and args in theProgram argumentsfield, e.g.,create-app com.example.demo --services=… --clouds=… --features=…
