java - Maven 提示 Joda-Time 即使我安装了它

Question

因为我想用ActiveAndroid和 ActiveAndroid-Validation我需要使用 Maven(直到昨天我才听说过)。所以我安装了maven，然后尝试安装ActiveAndroid。

我写了一个custom serializer在 ActiveAndroid 中使用 JodaTime并在 ActiveAndroid libs 文件夹中包含一个 JodaTime jar。当我使用 ant 构建项目时，它运行良好。首先使用 Maven downloaded并使用 JodaTime 源文件夹中的 mvn clean install 在 Maven 中安装 JodaTime。看到下面几行就成功了:

[INFO] --- maven-install-plugin:2.4:install (default-install) @ joda-time ---

然后我尝试使用相同的 mvn clean install 从 ActiveAndroid 源文件夹中安装 ActiveAndroid。然而，这导致了以下错误:

有人知道我该如何解决这个问题吗？欢迎所有提示!

==编辑== ActiveAndroid的pom.xml可以找到here .我没有更改任何内容。

如果您的 IDE 没有报错，则表示您的 IDE 可以构建项目。

那么我假设你的 IDE 不依赖 maven 来构建。我会建议 maven 和您的 IE 之间进行更强大的集成。 您不应该手动将库添加到您的类路径(在 IDE 中)

您的 POM 缺少依赖项

<dependency>
  <groupId>joda-time</groupId>
  <artifactId>joda-time</artifactId>
  <version>2.3</version>
</dependency>
