將maven庫項目更新為主項目（android）

Question

我試圖通過以下示例了解Maven Android插件： https ： //github.com/jayway/maven-android-plugin-samples/archives/stable

我正在使用示例“libraryproject”，一切都運行良好，只有一件我真的無法弄清楚：如果我改變了一些東西到lib1項目（例如資源文件的內容）和complile主項目，我仍然在生成的apk文件中看到舊資源。

我試着清理，重建，沒有改變我的apk ...

對不起因為我的英語不好這個愚蠢的問題。

編輯：我只是喜歡yorkw說：

但現在我收到以下錯誤：

Answer 1

您應該在父項目文件夾（../libraryprojects）中構建項目（mvn clean install），這將構建libraryprojects-lib1項目（以便將最新的apklib安裝到您的本地maven存儲庫中）以及libraryprojects-mainapp項目。

如果在子項目文件夾（../libraryprojects/libraryprojects-mainapp）中構建項目（mvn clean install），這將只構建libraryprojects-mainapp並使用存儲在本地maven存儲庫中的現有apklib來實現項目依賴性。 換句話說，libraryprojects-lib1項目重建沒有發生，並且有助於libraryprojects-mainapp項目的構建生命周期。

請注意，如果您在Eclipse中導入整個項目並通過Eclipse清理/構建libraryprojects-mainapp，它將自動觸發依賴庫項目libraryprojects-lib1的重建過程。

更新：

我已經下載了最新的android maven插件並在我的Windows XP盒子上試一試並復制了這個問題，它實際上是一個Microsoft Fault！ 如果您嘗試訪問（這是構建項目時創建的臨時文件夾Maven之一）：

C:\Users\nicola\Desktop\maven_example\jayway-maven-android-plugin-samples-c475bf4\libraryprojects\libraryprojects-mainapp\target\unpack\apklibs\com.jayway.maven.plugins.android.generation2.samples.libraryprojects_libraryprojects-lib2_apklib_1.0.0-SNAPSHOT\res

從資源管理器中，你得到：

點擊此處和此處了解更多詳情。 Windows上的最大路徑長度限制為256個字符。

解：

首先，嘗試使用短路徑，例如，可以找到以下內容：

    C:\c475bf4\libraryprojects\libraryprojects-mainapp\target\unpack\apklibs\com.jayway.maven.plugins.android.generation2.samples.libraryprojects_libraryprojects-lib2_apklib_1.0.0-SNAPSHOT\res

然后給它另一個嘗試，看看你是否可以構建它，你可能會得到另一個構建錯誤（我試過我的Windows XP框並得到此錯誤），如下所示：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0.1:compile (default-compile) on project libraryprojects-mainapp: Compilation failure: Compilation failure:
[ERROR] C:\c475bf4\libraryprojects\libraryprojects-mainapp\src\main\java\com\jayway\maven\plugins\android\generation2\samples\libraryprojects\mainapp\MainActivity.java:[16,5] annotations are not supported in -source 1.3

要解決此問題，您可以在.. \\ libraryprojects \\ pom.xml中指定更高版本的maven-compiler-plugin：

<plugin>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>2.3</version>
  <configuration>
    <source>1.6</source>
    <target>1.6</target>
  </configuration>
</plugin>

最后但並非最不重要的是，請注意您需要打開模擬器才能讓測試子項目運行檢測測試，否則構建測試項目將失敗。

希望這可以幫助。

Answer 2

我有同樣的問題，它的解決方案是使用Eclipse Marketplace更新/安裝Maven android配置器。 （Eclipse幫助 - > Eclipse marketplace - >找到maven android配置器並安裝它）

之前我還使用Eclipse幫助更新了m2e插件 - >檢查更新

如果它沒有幫助，那么嘗試逐步搜索錯誤。 我已經描述了在這里使用android和eclipse配置maven所需的所有步驟
