Question

因为我想使用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。

我使用custom serializer在ActiveAndroid中编写了一个JodaTime，并在ActiveAndroid libs文件夹中包含了一个JodaTime jar。当我使用ant构建项目时，它非常有效。首先使用Maven我downloaded并使用JodaTime源文件夹中的mvn clean install在Maven中安装JodaTime。看到以下几行，这是成功的：

[INFO] --- maven-install-plugin:2.4:install (default-install) @ joda-time ---
[INFO] Installing /Users/kramer65/Downloads/joda-time-2.3/target/joda-time-2.3.jar to /Users/kramer65/.m2/repository/joda-time/joda-time/2.3/joda-time-2.3.jar

然后我尝试使用ActiveAndroid源文件夹中的相同mvn clean install安装ActiveAndroid。但是，这导致了以下错误：

有人知道如何解决这个问题吗？欢迎所有提示！

== EDIT == 可以找到ActiveAndroid的pom.xml here。我没有改变任何内容。

Answer 1

如果您的IDE没有抱怨，则表示您的IDE可以构建项目。

然后我假设您的IDE不依赖于maven来构建。我建议maven和你的IE之间更强大的集成。您不应该将libs手动添加到类路径（在IDE中）

你的POM错过了依赖

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

Answer 2

由于你的构建中有android-maven-plugin，你需要提供SDK的路径。对于这个maven插件，可以通过在POM的属性部分中将其添加为属性（android.sdk.path）来完成。

所以你会有这样的事情：

<properties>
    <android.sdk.path>your/path/here</android.sdk.path>
</properties>

要快速解决方案，您只需将其添加到POM的属性部分即可。但是，像这样的本地设置通常会转到maven安装中conf dir中的settings.xml文件。无论您使用什么样的pom，这都会使这个属性始终存在。或者，如果您跳过activeProfiles部分，则必须在启用该配置文件的情况下调用maven - “mvn -pandroidProfile clean install”。

<profiles>
    <profile>
        <id>androidProfile</id>
        <properties>
            <android.sdk.path>your/path/here</android.sdk.path>
        </properties>
    </profile>
</profiles>
<activeProfiles>
    <activeProfile>androidProfile</activeProfile>
</activeProfiles>

关于Joda-Time的Maven抱怨，即使我安装了它
