我刚开始在我的项目中使用 Maven。

我将一个旧项目转换为一个 Maven 项目，起初一切正常。但现在我有一个问题。

当我尝试运行应用程序（使用 Objectify 的 GWT 应用程序）时，我收到以下错误：

SDK位置'/Users/abelbarbosa/.m2/repository/com/google/appengine/appengine-api-1.0-sdk/1.7.6/appengine-api-1.0-sdk-1.7.6.jar'不是目录

我知道它不是一个目录，但我认为它不应该是。我不知道如何纠正这个。

我的 pom.xml 有什么问题吗：

在您的项目构建路径中，确保 AppEngine 库位于您的 Maven 库之前。在这里查看如何设置它：https ://stackoverflow.com/a/15314586/1040124

评论中的文字出现乱码。所以这里重写，为appengine添加一个依赖：

<dependency>
  <groupId>com.google.appengine</groupId>
  <artifactId>appengine-api-1.0-sdk</artifactId>
  <version>1.8.1</version>
</dependency>

不确定它会解决问题，但告诉我们结果。

您必须使用 maven appengine 插件。https://code.google.com/p/maven-gae-plugin/
