Unable to import compiled java avro files into Scala codebase
问题
我正在尝试在我的Scala代码库中引用生成的Avro文件。我正在使用commercehub avro gradle插件生成Avro Java编译文件，并且它们被正确地生成在build/generated-main-avro-java/目录下。
这是我的gradle文件的样式。问题在于Java文件被正确生成，但我无法在我的Scala代码中导入它们。关于我可能在这里做错了什么，您有什么想法吗？

I am trying to reference the generated Avro files in my scala code basebase. I am using the commercehub avro gradle plugin to generate the avro java compiled files and they get correctly generated in build/generated-main-avro-java/
This is how my gradle file looks. The problem is that the java files get generated correctly but I cannot import them in my scala code. Any idea on what I maybe doing wrong here?

我会说，你需要将生成的源代码文件夹添加到源代码集和 Scala 编译器源代码中，类似于这样：
```gradle
compileScala {
source = ['src/main/scala', 'src/main/java', 'build/generated-main-avro-java/']
}
sourceSets {
main {
avro {
scala.srcDir file('build/generated-main-avro-java/')
}
}
}
英文:
I would say, you need to add the generated sources folder to source sets and scala compiler source - something like this:
compileScala {
source = ['src/main/scala', 'src/main/java', 'build/generated-main-avro-java/']
}
sourceSets {
main {
avro {
scala.srcDir file('build/generated-main-avro-java/')
}
}
}
