MojoExecutionException：带有 Android 的 Maven

Question

我正在使用带有 Maven 3.1.1 的 Android Studio，并且在包目标中它崩溃并出现 MojoExecutionException。我已经阅读了很多帖子，但我无法得到解决方案。

[ERROR] 生成来源时出错。

Answer 1

这个问题有点棘手，但可以解决！

首先，当您收到类似您收到的错误消息时，您应该尝试运行 Maven 说它无法运行的命令，因为在 maven 下载依赖项并构建代码等之后。Maven 它自己运行初始命令制作你的apk。你的情况是：

C:\Users\hvalls\AppData\Local\Android\android-studio\sdk\build-tools\19.0.3\aapt.exe package -f --no-crunch -I C:\Users\hvalls\AppData\Local\Android\android-studio\sdk\platforms\android-19\android.jar -M C:\Users\hvalls\Desktop\my-app\AndroidManifest.xml -S C:\Users\hvalls\Desktop\my-app\res -A C:\Users\hvalls\Desktop\my-app\target\generated-sources\combined-assets\assets -m -J C:\Users\hvalls\Desktop\my-app\target\generated-sources\r --output-text-symbols C:\Users\hvalls\Desktop\my-app\target --auto-add-overlay

因此，当您运行它时，它将为您提供 dx.bat 工具的真正错误输出。只需修复您在输出中看到的错误并重新运行 mvn。

就我而言，我收到此错误是因为我的 res 文件夹下的图像之一不是 png 文件，尽管扩展名是 png。在我修复了文件类型之后，它就可以工作了。

Answer 2

我遇到了同样的错误，我花了 2.5 个工作日才找出问题所在。 问题实际上是文件系统上的路径太长！是的，文件路径太长了！

我将项目从：

C:\work\workspaces\intelliJ\dory3

到

C:\work\n\dory

它立即奏效了。构建时没有错误，在 IntelliJ 中没有问题。

Answer 3

错误信息不多说，但它意味着构建你的android apk失败。如果您查看上述错误的 Maven 输出，您可能会看到带有实际错误的消息。在我的情况下是：

Extracting libs
Generating R file for Planer:AndroidApk:apk:1.0.0
C:\NetBeansProjects\Planer\AndroidApk\res\values\strings.xml:30: error: Resource entry ui.separator is already defined.
C:\NetBeansProjects\Planer\AndroidApk\res\values\strings.xml:29: Originally defined here.

Error when generating sources.
org.apache.maven.plugin.MojoExecutionException: 
    at com.jayway.maven.plugins.android.phase01generatesources.GenerateSourcesMojo.generateR(GenerateSourcesMojo.java:894)
    at com.jayway.maven.plugins.android.phase01generatesources.GenerateSourcesMojo.execute(GenerateSourcesMojo.java:323)
...
Caused by: com.jayway.maven.plugins.android.ExecutionException: ANDROID-040-001: Could not execute: Command ....
...

如您所见，有关问题的信息是在 maven 错误上方输入的。例如，我的问题是字符串资源的重复——由于某种原因，Android Studio 已经复制了。因此，您不必自己运行该命令。只看输出。
