*更新*

也许我在这里做错了但是如果是这样的话，我不清楚是什么。这是一个已知的问题？我是否应该寻找特定的地方，以确定是否存在未满足的依赖关系等（如Java版本或IDE版本或插件或？）。请帮忙。

情景：

  • 我有最新的IntelliJ Idea版本（14.1.7）
  • 使用java -version）
    • 从IDE终端确认Java版本为1.8.0_91
  • 刚刚更新为CN1插件版本3.7.1
  • 刚刚启动了一个新项目，可以使用新的GUI Builder。

以下是重现的步骤：

  1. 我右键点击包裹并选择＆＃34;新表格＆＃34;并给它一个名字
  2. 创建表单java文件和.gui文件
  3. 我右键单击java文件并选择＆＃34; CN1-＆gt; Gui Builder＆＃34;

    4. 然后Idea使用以下详细信息来解决错误事件（NoSuchMethodError）：并且GUI生成器不会显示

    堆栈追踪：

    *更新* 基于一些好的建议，我意识到我的Idea版本已经多大了，所以我已经升级到2017.1.4。我删除并重新安装了3.7插件，我的测试项目仍无法启动GUI Builder，但现在有不同的错误和堆栈跟踪：

2 个答案:

答案 0 :(得分：2)

显然，您安装的插件版本3.7.1与IntelliJ IDEA 14.1.7不兼容。开发人员错误地指出它兼容而不执行真正的测试。由于14.1.7很旧，以前没有人注意到这个问题。因此，要么更新当前的IntelliJ IDEA版本，请尝试手动安装一些较旧的插件版本，或file a bug to the plug-in developer。

至于第二个问题，请check this answer。

答案 1 :(得分：0)

事实证明，我的Idea配置有一个较旧的Java（Android！）SDK配置为新项目的默认值。这个默认设置导致新项目CREATION做了一些奇怪的事情，导致它无法使用GUI Builder。仅在我的项目配置中修复不正确的SDK并没有使GUI Builder在预先存在的项目中工作;相反，我需要使用正确的SDK集创建一个新项目，然后它开始工作。也许可能有一个步骤迫使CodenameOne在修复后“重新创建”或“重新生成”项目，但这对我来说并不明显。

@Shai Almog，我希望这至少可以为你提供一些关于这个问题如何发生的线索，这样你就可以防止它在将来影响他人。现在我的问题是解决。感谢所有人的帮助。
