【问题描述】：
我刚刚使用 maven 启动了一个新的 vaadin 项目 (com.vaadin:vaadin-archetype-application@7.2.6)。
在默认的 MyVaadinUI.java 中，我已将 Butten.ClickListener() 替换为 lambda 表达式，之后在运行 package jetty:run 时出现异常
之前：
Button button = new Button("Click Me");
button.addClickListener(new Button.ClickListener() {
public void buttonClick(ClickEvent event) {
layout.addComponent(new Label("Thank you for clicking"));
}
});
layout.addComponent(button);
之后：
Button button = new Button("Click Me");
button.addClickListener(event -> layout.addComponent(new Label("Thank you for clicking")));
layout.addComponent(button);
例外：

我在 OSX 上使用 IntelliJ13.1 和 JDK8
【问题讨论】：
-
我会说您的ASM 版本不支持Java 8。Jetty 正在使用ASM 扫描二进制类以查找注释。
-
谢谢，更新
jetty-maven-plugin为我解决了这个问题。 -
谢谢，我遇到了同样的问题，使用 jetty-maven-plugin 9.2.2.v20140723 而不是 9.0.6.v20130930 解决了这个问题。
-
您好，您使用的是什么版本的码头？我正在使用 8.1.16.v20140903，但我仍然遇到同样的问题。
-
@CodeJunkie 我遇到了与
Jetty 8.1.2.v20120308相同的问题，正如@Schrodinger's'Cat 所说，您可以升级到 9.2.2，它应该可以修复。
