如何克服构建 Zxing android 应用程序时缺少的依赖项？

Question

我正在尝试使用说明 here 构建 Zxing android 应用程序（不是库）。我能够构建罐子但无法构建应用程序本身。当我运行 mvn package android:apk 我得到以下错误：

[INFO] Scanning for projects...
[ERROR] [ERROR] Some problems were encountered while processing the POMs:
[ERROR] 'dependencies.dependency.version' for com.google.android:android:jar is missing. @ line 34, column 17
 @

如有任何帮助，我们将不胜感激。更好的是一些关于使用 Android Studio 构建应用程序的说明。

Answer 1

检查您是否没有错过 <dependencyManagement> 依赖项标记。

您也可以查看 this 答案以便更好地理解。

Answer 2

你可以从下面这行看出错误在哪里

[ERROR] 'dependencies.dependency.version' for com.google.android:android:jar is missing. @ line 34, column 17

您需要向依赖项添加有效的 <version> 标记。检查工件的 Maven repository，我们可以看到最新版本是 4.1.14。

确保包含依赖项的 POM 看起来像

<platform.version>4.1.1.4</platform.version>

这也被作为答案提到 here 所以我想你遇到了同样的问题。
