Folder "generatedsources" is created, even when the task "xsd2java" is not used

Workaround is:

xsd2java{
    generatedXsdDir = file("generated-sources")
}

Thanks for the. I am not sure how we can avoid this, as it is the "@OutputDirectory" annotation wich creates this in the first place. If I remove the annotation, the task will stop beeing incremental as I see it. Or do you have a solution for this @fowlie ?

Maybe the cleanest solution would be to extract the xsd-task into a separate plugin instead of mixing it into the wsdl2java plugin?

You don't have to declare the output directory to get incremental build. But I think it's a good practise. Why? If someone is clever enough (new junior developer in the team) changes a generated java class, they might think it's all fine. Because their changes will stay there the whole time, until one day someone changes the input source files and the java classes are regenerated.

If you do a change in a generated file, then the change will be lost on the next build, and then you'd immediately realize that you've just changed a generated file.

To get the build incremental, it's enough with the input annotation. So that every time the source files gets updated, the java classes are regenerated. And when they don't change, Gradle will skip the task. That's the most important thing.

@shalugin any particular reason you don't want the directory to be created even if it's empty? In our team, we have everything generated inside the build directory. That way you can clean everything with the gradle clean command.

Okey, now I understand your problem. 😄 You are not using xsd2java at all! So the problem is that the tasks have different output paths. One way to easily solve this could be to always put generated code in e.g. build/generated-sources. And then the generatedWsdlDir would be relative to that directory.

I think, that is the best solution.
Another one is not to execute xsd2java or wsdl2java by default. And execute it only when it called explicitly.

For example:

compileJava.dependsOn xsd2java
