Service Builder 不编译依赖 IVY jar 的代码

Question

我有一个基本程序，其中包含一个用于服务构建器的简单实体，没有用于 Web 服务调用的属性。我在本地依赖 javax.ws.rs-api-2.0.1.jar 中包含的 javax.ws.rs 库。

在 IDE 中，代码没有显示任何错误。我可以在项目资源管理器窗口中看到 Ivy 依赖项。但是，当我调用 build-services 命令时，它无法使用外部 jar 中的类编译代码。

在我的应用程序中依赖 jar 时，我错过了一步吗？这不应该自动链接吗？

蚂蚁输出：

亲切的问候， 代码。

您几乎自己回答了这个问题，但不是很明显：当 servicebuilder 运行时，它会执行一些需要与项目的类路径一起运行的 java 代码：ServiceBuilder 将编译/检查您的代码以生成适当的接口等等

因此，您还需要将项目的依赖项注入到 servicebuilder 进程中。当您从 IDE 运行 servicebuilder 时，它很可能正在运行 Ant 任务，该任务将从 webapp 获取所有明显的（对 ant 而言）依赖项（例如，它在 WEB-INF/lib 和应用服务器的全局类路径中找到的内容）。 Ant 进程不会扫描任何 ivy、maven 或其他构建工具的依赖声明 - 不幸的是，您必须添加此依赖两次。
