I need some help to understand how to configure openapi-generator to use BigDecimal for string+decimal (while having DTO suffix).
On package.json I have:
"@openapitools/openapi-generator-cli": "2.31.1",
On my yaml file I specified a type:
components:
schemas:
BankAccount:
type: object
required:
- id
- name
- balance
properties:
id:
type: integer
format: int64
name:
type: string
balance:
type: string
format: decimalFor Java, I want it to generate BankAccountDTO and use java.math.BigDecimal for the balance.
I'm using gradle, but it's a simple wrapper to call node command:
val generateServerAPITask = tasks.register<NpxTask>("generateServerAPI") {
dependsOn("npmInstall")
dependsOn(createApiOutputDirTask)
workingDir.set(apiOutputDir)
val outputDir = apiOutputDir.get().dir("server")
command.set("@openapitools/openapi-generator-cli")
args.set(listOf(
"generate",
"-i", apiSpecFile.absolutePath,
"-g", "jaxrs-spec",
"-o", outputDir.asFile.absolutePath,
"--model-name-suffix", "DTO",
"--api-package", "com.ralmeida.txc2.web.ws.api",
"--model-package", "com.ralmeida.txc2.web.ws.dto",
"--type-mappings", "string+decimal=BigDecimal",
"--import-mappings", "BigDecimal=java.math.BigDecimal",
"--language-specific-primitives", "java.math.BigDecimal",
"--global-property", listOf(
"models",
"apis",
"supportingFiles=false" // Avoids README and other noise
).joinToString(","),
"--additional-properties", listOf(
"interfaceOnly=true",
"useJakartaEe=true",
"dateLibrary=java8",
"returnResponse=true",
"serializationLibrary=jackson",
"generatePom=false",
"useSwaggerAnnotations=false",
"openApiNullable=false",
).joinToString(",")
))
inputs.file(apiSpecFile)
outputs.file(apiOutputDir.get().file("openapitools.json"))
outputs.dir(outputDir)
}I've been playing with the arguments but can never make it understand that BigDecimal is part of java... it always seem to try to use a non-existant BigDecimalDTO
> Compilation failed; see the compiler output below.

What arguments am I missing? Or could it be a bug?
