CodenameOne GUI Builder將NPE在崩潰的IntelliJ IDEA

Question

*將下面的更新*

也許我在這裏做得不對，但如果是這樣，這不是很清楚，我什麼。這是一個已知的問題？我是否應該在特定的地方查找是否存在未滿足的依賴關係等（如Java版本或IDE版本或插件或？）。請幫忙。

場景：

• 我已經得到了最新的IntelliJ IDEA版本（14.1.7）
• Java版本是1.8.0_91使用java -version）
• 剛剛更新到CN1 IDE從終端證實插件版本3.7.1
• 剛剛開始一個新的項目，使用新的GUI生成器。

下面是步驟來重現：

1. 包裝上我單擊鼠標右鍵，選擇「新建表」，並給它一個名稱
2. 形式的java文件和.gui文件被創建
3. 我對java文件上右鍵單擊，選擇「CN1-> GUI生成器」

然後理念barfs出一個錯誤事件（的NoSuchMethodError）並具有以下細節：和在GUI Builder不露面

堆棧跟蹤：

* UPDATE * 基於一些很好的意見，我意識到我的想法只是版本幾歲了，所以我已經升級到2017.1.4。我刪除並重新安裝3.7插件，以及我的測試項目也無法啓動GUI Builder中，但現在有一個不同的錯誤和堆棧跟蹤：

Answer 1

事實證明，我的Idea配置有一個較舊的Java（Android！）SDK配置爲新項目的默認值。這個默認值導致新項目CREATION做了一些奇怪的事情，導致它無法使用GUI Builder。在我的項目配置中修復不正確的SDK不會使GUI Builder在預先存在的項目中工作;相反，我需要用正確的SDK集創建一個新項目，然後開始工作。也許可能有一個步驟來強制CodenameOne在修復後「重新創建」或「重新生成」項目，但這對我來說並不明顯。

@Shai Almog，我希望這至少能爲你提供一些線索，告訴你這個問題是如何發生的，以防止它在將來影響他人。目前我的問題是解決。感謝所有的幫助。

Answer 2

顯然，插件版本3.7.1已安裝的與IntelliJ IDEA 14.1.7不兼容。開發人員錯誤地指出，它沒有執行真正的測試是兼容的。由於14.1.7相當老，以前沒有人注意到這個問題。因此，要麼更新到當前的IntelliJ IDEA版本，請嘗試手動安裝一些較舊的插件版本或file a bug to the plug-in developer。
