schema-gen's Issues

Invalid `static` keyword for nested Kotlin classes

The generated Kotlin code gets the keyword static added to inner Kotlin classes. This keyword does not exist. In Kotlin, all inner classes are by default static; to have a non-static inner class, Kotlin requires the developer to add the inner keyword in front of the inner class.

Invalid enum and variable names

When generating Kotlin classes from the following schema:
https://edavki.durs.si/Documents/Schemas/Doh_KDVP_9.xsd

I encountered the following issues:

  1. TypeInventoryEnum.Unknown is used but not generated, which causes syntax error.
  2. This seems to be Jackson related, but can also be 'fixed' here: If variable has name with inverse case, for example kDVP, it is serialized to lowercase XML tag 'kdvp' regardless of property localname='KDVP'. Solution: rename var in generated code to lower case ('kdvp'). Note: It seems that XML tag is serialized as lowercase by Jackson if the first letter of var name is lower case, and the second is upper case. The rest is not important.
  3. @JsonPropertyOrder annotation is missing for sequences of XML elements to preserve element order on

serialization.
4. Property @JacksonXmlProperty(namespace=...) is not generated for elements with namespace.

class com.javagen.schema.java.JavaGen, unresolved supertypes: FieldHelper

When building the build.gradle.kts file I get an exception:

import org.jetbrains.kotlin.gradle.tasks.KotlinCompile

plugins {
    kotlin("jvm") version "1.3.0"
    id("com.javagen.schema-gen") version "0.9.1"
}

repositories {
    mavenCentral()
}

dependencies {
    compile(kotlin("stdlib-jdk8"))

    implementation("com.github.ajalt:clikt:1.3.0")
    implementation("io.github.config4k:config4k:0.4.1")
}

tasks.withType<KotlinCompile> {
    kotlinOptions.jvmTarget = "1.8"
}

schemaGen {
    kotlin {
        srcDir = File("")
    }
}

The exception that is thrown is:

Script compilation error:

  Supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath:
      class com.javagen.schema.java.JavaGen, unresolved supertypes: FieldHelper

Could you explain how this issue van be solved?

Compiled

I figured out (via googling) that to fix these errors I had to compile the classes 'bottom up' to a 'bin' folder which I then used as the classpath. This fixed the 'unable to resolve' and 'class.this' / 'class.super' errors.

groovyc -d=./bin com/javagen/schema/model/*
groovyc -d=./bin com/javagen/schema/common/*
groovyc -cp=./bin -d=./bin com/javagen/schema/xml/node/*
groovyc -cp=./bin -d=./bin com/javagen/schema/xml/*.groovy

All seems ok until I try to compile java

groovyc -cp=./bin -d=./bin com/javagen/schema/java/*.groovy

This is from trying to process "clarivate.com.schema.wok5.27.rawxml.xsd" and its children XSDs.

The output reads like the FullRecord xsd is trigguring something to pull itself in again as a new file for processing ... ad infitum till stack out of space.

The file only has an "include" for "common_types.rawxml.xsd" which includes "EWUID.rawxml.xsd" which back references "common_types.rawxml.xsd" as an include ...

<?xml version="1.0" encoding="UTF-8"?>

So I set the gen source to "common_types ... xsd" and get the same error.

First of all, thanks for the great tool.

I have imported a rather large schema and I have encountered one issue:

The fractionDigits facet throws an exception.

TODO -> IllegalStateException

I want to generate kotlin code from a xsd schema that is "well formed and valid". There is no registered namespace, so the XmlSlurper constructor is called with true, false. The error messages suggest that the code generation does not cover all use cases:

Warning: validation was turned on but an org.xml.sax.ErrorHandler was not
set, which is probably not what is desired. Parser will use a default
ErrorHandler to print the first 10 errors. Please call
the 'setErrorHandler' method to fix this.

No namespace registered for prefix

Hello,

I'm trying to use your work to generate Swift code from AIXM XSD (standard file format to define airspaces).

I'm facing the error no namespace registered for prefix 'null' for name: alpha for every single object definition in the published document.

Here is a sample part of the XSD that generate the error.

Am I doing something wrong? How should I solve this issue?

still usable?

Hi,

I am trying to use this service, but I cannot find a working example.

When I try to use the dependency in gradle, I always get

Searched in the following locations:
       - https://repo.maven.apache.org/maven2/com/javagen/schema-gen/0.9.1/schema-gen-0.9.1.pom
     If the artifact you are trying to retrieve can be found in the repository but without metadata in 'Maven POM' format, you need to adjust the 'metadataSources { ... }' of the repository declaration.

I cannot see anything pointing to a dependency in this repository and the gradle plugin seems not supported.
So is this still being used?

Cannot get property 'imports' on null object

I'm trying to generate Kotlin classes for my XSDs. This is the calling code:

class CodeGen extends KotlinGen {
    CodeGen(File schemaFile, File targetDir, String targetPackage) {
        super()
        schemaURL = schemaFile.toURI().toURL()
        srcDir = targetDir
        packageName = targetPackage
        addSuffixToEnumClass = null
        anyPropertyName = 'text'
    }
}

The XSD file is valid (and was used to create Java Beans via xjc before), the targetDir is valid as well and exists, the package name is non-empty. When I execute this code in my custom task, I receive the following crash:

java.lang.NullPointerException: Cannot get property 'imports' on null object

My Groovy-foo is not good enough to figure out whats going on here, so maybe you have an idea?

[Question]: Run without plugin

Hello!

I've encountered issue described here #10 but with different scheme. I ran schema-gen with gradle plugin. As far as I understand the problem has been fixed but I need to run schema-gen "directly" (since plugin is not supported any more).

I'm not familiar with groovy, gradle etc. Could you please elaborate what does it mean "The main entry point is com.javagen.schema.swift.SwiftGen which can be invoked directly"?

What tools I need to install?
How to build schema-gen itself?
How run schema-gen without gradle plugin?

Sample for Kotlin/JS?

Hi Richard,
I would like to use schema-gen for a Kotlin/JS project.
Do you know of any projects/samples?

Thanks in advance

Complex element with choice is not generated correct anymore

This worked in V 0.9.1.

Xsd-snippet:

<xsd:complexType name="KontoForTilbakebetaling">
	<xsd:sequence>
		<xsd:choice>
			<xsd:sequence>
				<xsd:element name="norskKontonummer" type="Kontonummer"/>
			</xsd:sequence>
			<xsd:sequence>
				<xsd:element name="swiftBIC" type="Tekst"/>
				<xsd:element name="valuta" type="Valutakode"/>
				<xsd:element name="IBAN" type="Tekst"/>
			</xsd:sequence>
		</xsd:choice>
	</xsd:sequence>

used to generate (Kotlin):

  data class KontoForTilbakebetaling(
      val norskKontonummer:String? = null, 
      val swiftBIC:String? = null, 
      val valuta:String? = null, 
      val IBAN:String? = null
  )
  {
  }

And the latest code generates:

  data class KontoForTilbakebetaling(
  val norskKontonummer:String? = null, 
  )
