關於Joda時間的Maven投訴，儘管我安裝了它

Question

因爲我想使用ActiveAndroid和ActiveAndroid-Validation我需要使用Maven（直到昨天我才聽說過）。所以我安裝了maven，然後嘗試安裝ActiveAndroid。

我在ActiveAndroid中使用JodaTime寫了一個custom serializer，並在ActiveAndroid庫文件夾中包含了一個JodaTime jar。當我使用ant構建項目時，它工作得非常好。首先使用Maven downloaded並在Maven中使用mvn clean install從JodaTime源文件夾中安裝JodaTime。看到下面的線，這是成功的：

[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

然後我試圖安裝ActiveAndroid使用相同mvn clean install從ActiveAndroid源文件夾中。然而，這導致了以下錯誤：

有沒有人知道我可以解決這個問題？歡迎所有提示！

==編輯== ActiveAndroid的pom.xml可以找到here。我沒有改變任何東西。

Answer 1

如果您的IDE沒有抱怨，這意味着您的IDE可能會構建該項目。

然後我假設你的IDE不依賴maven來構建。我會建議maven和你的IE之間的更強大的整合。 你不應該到庫手動添加到類路徑中（在IDE）

你的POM小姐的依賴

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

正如你在你構建一個Android，Maven的插件，您需要提供SDK的路徑。對於這個maven插件，這是通過在POM的屬性部分添加它作爲屬性（android.sdk.path）來完成的。

所以你有這樣的事情：

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

對於快速的解決方案，你可以添加這個到POM的屬性部分。但是，像這樣的本地設置通常會轉到maven安裝中的conf目錄下的settings.xml文件。無論你使用哪種物品，這都會使這個物品永遠在場。或者，如果您跳過activeProfiles部分，則必須調用啓用了該配置文件的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>
