Unable to be compatible with high version of gradle !

distributionUrl=https://services.gradle.org/distributions/gradle-5.1.1-all.zip
classpath 'com.android.tools.build:gradle:3.4.1'

Such a configuration cannot generate a file in build/generated/source/apt/debug

[Egorand]

It'd be helpful to have a sample project that reproduces the issue. My feeling is that JavaPoet isn't the culprit here.

[EspoirX]

You can create a simple APT example to reproduce，like this:

    @AutoService(Processor.class)
    public class MyProcessor extends AbstractProcessor {
        
        private Filer mFiler;
     
        @Override
        public synchronized void init(ProcessingEnvironment processingEnvironment) {
            super.init(processingEnvironment);
            mFiler = processingEnv.getFiler();
        }

        @Override
        public boolean process(Set<? extends TypeElement> set, RoundEnvironment roundEnvironment) {
            TypeSpec finderClass = TypeSpec.classBuilder("MyTestClass")
                    .addModifiers(Modifier.PUBLIC)
                    .build();
            JavaFile javaFile = JavaFile.builder("com.example.demo", finderClass).build();
            try {
                javaFile.writeTo(mFiler);
            } catch (IOException e) {
                e.printStackTrace();
            }
            return true;
        }

        @Override
        public Set<String> getSupportedAnnotationTypes() {
            Set<String> types = new LinkedHashSet<>();
            types.add(Override.class.getCanonicalName());
            return types;
        }
    }

as you said，I am not sure the problem is in JavaPoet or google#auto-service，But after I lowered the gradle version, the problem was solved. So I hope that you can follow up to make sure it is not a JavaPoet issue.

How are your dependencies configured? And which older version of Gradle is working?
In 5.0 for example, Gradle stopped using processors from the compile classpath, you have to declare your processor dependencies in the annotationProcessor configuration.

[EspoirX]

yes，My configuration is correct，like this，
annotationProcessor project(':compiler')

Please provide a full sample project in the form of a zip or GitHub repo that reproduces the problem.

thanks!

Your AutoService dependency should be in both api (or compileOnly as the annotation has source retention) and annotationProcessor.
I haven't tried the project but that alone would break it with Gradle 5.0, as explained earlier.

[WangPney]

I have the same problem

[WangPney]

My gradle build is gradle-5.1.1-all.zip
Gradle version is 3.4.1
The problem I encountered was also a class generation failure. Do I have to downgrade to use it @ @tbroyer

[EspoirX]

you should downgrade to use it @lichangxing

[Shadowself]

So Have you solved it?
