我正在尝试制作一个自定义注释处理器并且它没有被调用。虽然它是.init,但它似乎从未调用过.process。任何帮助将不胜感激!
版本:
- 科特林(1.3.72)
- JRE(11.0.7)
- Maven(3.8.0)
这是我从控制台的输出:
[INFO] --- maven-compiler-plugin:3.8.0:compile (java-compile) @ mesh ---
[INFO] Changes detected - recompiling the module!
Processor is being init!!
Processor is done init!!
注解:
package my.path.annotations
@Target(AnnotationTarget.CLASS)
annotation class MyAnnotation()
注释处理器:
package my.path.annotations
import <...>
@SupportedAnnotationTypes("my.path.annotations.MyAnnotation")
class MyAnnotationProcessor : AbstractProcessor() {
private var elementUtils: Elements? = null
private var messager: Messager? = null
@Synchronized
override fun init(env: ProcessingEnvironment?) {
println("Processor is being init!!")
super.init(env);
elementUtils = env!!.elementUtils;
messager = env.messager;
println("Processor is done init!!")
}
override fun process(annotations: MutableSet<out TypeElement>?, roundEnv: RoundEnvironment): Boolean {
println("Processor is being run!!!")
return true
}
override fun getSupportedSourceVersion(): SourceVersion? = SourceVersion.latestSupported()
}
