- 預編譯標誌應該做什麼？

我正在使用勺子在註釋類上生成代碼，所以我可以減少我正在處理的項目的樣板和代碼重複。- 預編譯標誌應該做什麼？

由於該項目是非常小的我一直在尋找途徑，所以我不必整個事情分成已到，爲了進行編譯，所以我AnnotationProcessor兩個甚至三個不同的項目可在

看着the Spoon documentation我發現了--precompile這個標誌，據我瞭解，它應該預編譯整個源代碼並將其添加到類路徑中，所以Spoon將在運行時找到處理器和其他東西。

但是根據我在運行時得到的錯誤，它似乎沒有工作，即使添加了該選項，我仍然錯過了處理器。

唉這條線是什麼讓我困惑...

...因爲是的，我沒有使用 - 預編譯選項。感謝您詢問

^{Maven插件聲明使用EXEC-Maven的插件（它執行任何Java可執行文件）}

所以運行勺子：什麼是 - 預編譯標誌應該做什麼？
分別是我做錯了什麼？

編輯：
這裏有一個Maven的POM並說明如何在不使用maven運行並顯示自述一個簡單的例子：https://github.com/CrumbleWorks/Spoon-Precompile-Issue

是org.crumbleworks.forge.jhtml5.spoon.AttributeProcessor.class在類路徑？ –

@MartinMonperrus它是正在編譯的代碼的一部分 –

@MartinMonperrus我已經添加了一個演示問題的示例項目 –

的--precompile選項編譯提供的源代碼作爲輸入，因此對於所有CtTypeReference對象，可以使用getActualClass()獲得實際的類。此外，它還可以使getActualClass()適用於任何 CtType。

（這允許在同一個分析或改造與Java的反射混合勺的反射）
