java - 将 Cofoja 与 Wicket 一起使用(甚至仅与 Maven 一起使用)

Question

我正在尽最大努力让 Google Cofoja 在我的 Apache Wicket 中运行使用 Maven2 的应用程序似乎是标准的。

该项目最初是使用 Leg Up 生成的选择原型(prototype)“Wicket 1.4.12、Guice 2.0、WarpPersist 2.0(快照)、Hibernate 3.5.6”。

我最近尝试过的(似乎是最接近工作的)是使用 maven 进行构建(我已经设法构建了合约类)，然后尝试使用 ant 运行项目来获取进行契约(Contract)检查。 当前的问题是我不确定如何创建我的main类。我尝试将其设置为运行jetty服务器的类，但我得到的类不是发现异常。

J:\adminconsole>ant run
Buildfile: J:\adminconsole\build.xml

run:
     [java] java.lang.NoClassDefFoundError: com/mycompany/myproject/adminconsole/Start
     [java] Caused by: java.lang.ClassNotFoundException: com.mycompany.myproject.adminconsole.Start

     [java] Could not find the main class: com.mycompany.myproject.adminconsole.Start. Program will exit.

BUILD SUCCESSFUL

同样，即使我确实让这个解决方案发挥作用，这也远非将契约(Contract)检查作为 Maven 构建的一部分进行的理想解决方案。

现在，我目前拥有的:

如果你知道如何解决我当前的 Ant 问题，或者更好的是，知道如何一起废弃 Ant 黑客，那将是非常令人兴奋的(:

从代码中删除了 -，因为这很糟糕(感谢@Martijn Dashorst)。遗憾的是，这并没有解决问题。

请勿在 Artifact 和组 ID 中使用-。它们是无效的 Java 标识符字符。该脚本使用 groupId 和 artifactId 在您的项目中生成包名称。
