Question

我正在开发一个IntelliJ插件，我在其中生成Builder模式。但是，由于名为PluginException的东西，我似乎无法使用该插件。我在与this post相同的五个步骤中重现了错误，因为没有回答，我决定在这个问题中给出一些代码示例（我不允许对另一个问题发表评论。这有很多也是这样做的。）

可以找到代码here。 test-plugin应该在当前类中生成一个带有getter的字段，以及一个新类型的内部类（NumberFactory）。我在安装插件后得到的堆栈跟踪如下：

*cannot create class "be.koen.wellens.MyBuilderGeneratorAction" [Plugin: be.koen.wellens]: cannot create class "be.koen.wellens.MyBuilderGeneratorAction" [Plugin: be.koen.wellens]
com.intellij.diagnostic.PluginException: cannot create class "be.koen.wellens.MyBuilderGeneratorAction" [Plugin: be.koen.wellens]
