- 预编译标志应该做什么？

我正在使用勺子在注释类上生成代码，所以我可以减少我正在处理的项目的样板和代码重复。- 预编译标志应该做什么？

由于该项目是非常小的我一直在寻找途径，所以我不必整个事情分成已到，为了进行编译，所以我AnnotationProcessor两个甚至三个不同的项目可在

看着the Spoon documentation我发现了--precompile这个标志，据我了解，它应该预编译整个源代码并将其添加到类路径中，所以Spoon将在运行时找到处理器和其他东西。

但是根据我在运行时得到的错误，它似乎没有工作，即使添加了该选项，我仍然错过了处理器。

唉这条线是什么让我困惑...

Caused by: spoon.SpoonException: Unable to load processor "org.crumbleworks.forge.jhtml5.spoon.AttributeProcessor" - Check your classpath. Did you use the --precompile option?

...因为是的，我没有使用 - 预编译选项。感谢您询问

^{Maven插件声明使用EXEC-Maven的插件（它执行任何Java可执行文件）}

所以运行勺子：什么是 - 预编译标志应该做什么？
分别是我做错了什么？

编辑：
这里有一个Maven的POM并说明如何在不使用maven运行并显示自述一个简单的例子：https://github.com/CrumbleWorks/Spoon-Precompile-Issue

是org.crumbleworks.forge.jhtml5.spoon.AttributeProcessor.class在类路径？ –

@MartinMonperrus它是正在编译的代码的一部分 –

@MartinMonperrus我已经添加了一个演示问题的示例项目 –

的--precompile选项编译提供的源代码作为输入，因此对于所有CtTypeReference对象，可以使用getActualClass()获得实际的类。此外，它还可以使getActualClass()适用于任何 CtType。

（这允许在同一个分析或改造与Java的反射混合勺的反射）
