推荐答案

如果您使用的是Java8，那么您无需直接运行apt任务；它可能在幕后发生.

If you are using java8; then you don't need to run the apt task directly; it can happen behind the scenes.

来自ANT自己的文档:

From ANT's own documentation :

此任务在Java 1.5到Java 1.7上运行.

This task runs on Java 1.5 to Java 1.7.

Apt在Java 1.6中已弃用，它可以作为Javac的一部分运行注释处理器，并已从Java 1.8的发行版中删除.尝试在Java 1.8下运行时，该任务将引发异常.

Apt is deprecated in Java 1.6, which can run annotation processors as part of javac, and removed from the distribution in Java 1.8. The task will fire an exception when attempting to run under Java 1.8.

但是，这意味着您需要确保自定义注释处理器在执行javac时位于类路径中.

However, all that means is that you need to make sure that your custom annotation processor is in the classpath at the point of executing javac.

   <javac source="${javac.version}" target="${javac.version}" destdir="${classes.build.dir}" srcdir="${src.dir}" debug="on" debuglevel="source,lines">
      <classpath>
        <!-- make sure this has "my-annotation-processor.jar" -->
        <path refid="main.classpath"/>
      </classpath>
    </javac>
