java - appengine-api-1.0-sdk-1.7.6.jar 不是目录

Question

我刚开始在我的项目中使用 Maven。

我将一个旧项目转换为 Maven 项目，起初一切正常。但是现在我遇到了问题。

当我尝试运行该应用程序(是一个使用 Objectify 的 GWT 应用程序)时，出现以下错误:

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，但我不认为它应该是。我不知道如何纠正这个问题。

是不是我的pom.xml有问题:

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
