generateImmutableModels = true conflicts with generateNoArgsConstructorOnly = true

[asoftwareguy]

Issue Description

When configuring the Gradle plugin, I want the code generator to produce immutable objects, so I set the config as:

graphqlCodegen {
    // other config...
    generateImmutableModels = true
}

This still produced the public constructor, so I tried adding:

graphqlCodegen {
    // other config...
    generateImmutableModels = true
    generateNoArgsConstructorOnly = true
}

This resulted in non-compiling code.

Steps to Reproduce

The steps to reproduce should be the same as listed above. None of the other config values I had defined seemed to affect the behavior.

Expected Result

When generateImmutableModels is set to true, the all args constructor should be generated as package-private regardless of the setting for generateNoArgsConstructorOnly.

Actual Result

generateNoArgsConstructorOnly = true completely eliminates the all args constructor, resulting in non-compiling code.
generateNoArgsConstructorOnly = true leaves a public constructor, so the object is not immutable.

Your Environment and Setup

• graphql-java-codegen version: 5.8.0
• Build tool: Gradle

def graphqlCodegenSourcesDir = "$buildDir/generated/sources/graphqlCodegen"
sourceSets.main.java.srcDirs += graphqlCodegenSourcesDir

graphqlCodegen {
    graphqlSchemas {
        rootDir = "$projectDir/src/main/resources/graphql"
    }
    generateApis = false
    generateEqualsAndHashCode = true
    generateImmutableModels = true
    generateNoArgsConstructorOnly = true
    generateToString = true
    modelValidationAnnotation = '@javax.annotation.Nonnull'
    outputDir = new File(graphqlCodegenSourcesDir)
    packageName = 'a.b.c.graphql.model'
}
