编译Android项目与库项目失败，缺少classes.jar [英] Compiling android project with a library project fails with missing classes.jar

问题描述

我在做这取决于Android的V7应用程序兼容性支持库的应用程序。当我试图建立与Ant的项目，我从地塞米松，指出它无法找到从应用程序兼容性项目的bin目录下的文件classes.jar错误。下面是我做了什么：

I'm making an app that depends on the Android v7 appCompat support library. When I'm trying to build the project with Ant, I get an error from dex stating that it can't find the file classes.jar from the appCompat project's bin directory. Here's what I have done:

1. 我复制的SDK下的应用程序兼容性目录到我的项目。它现在是与库，水库，SRC等沿顶级目录中的一个。



2. 我添加库到我的项目：

1. I copied the appCompat directory under the SDK over to my project. It is now one of the top-level directories along with libs, res, src etc.

2. I added the library to my project:

android update project --target 1 --path . --library .\appCompat

（ - 1目标指的是API 22级我的系统上）

(--target 1 refers to api level 22 on my system.)

我产生建立的应用程序兼容性项目文件：

I generated build files for the appCompat project:

cd appCompat
android update lib-project --target 1 --path .

我回到我的项目，并试图构建它：

I went back to my project and attempted building it:

cd ..
ant clean debug

一切顺利，直到我得到以下几点：

Everything goes smoothly until I get the following:

-dex:
      [dex] input: C:\Users\Tuukka\Documents\app\bin\classes
      [dex] input: C:\Users\Tuukka\Documents\app\appcompat\bin\classes.jar
      [dex] input: C:\Users\Tuukka\Documents\app\appcompat\libs\android-support-v4.jar
      [dex] input: C:\Users\Tuukka\Documents\app\appcompat\libs\android-support-v7-appcompat.jar
      [dex] Pre-Dexing C:\Users\Tuukka\Documents\app\appcompat\libs\android-support-v4.jar -> android-support-v4-7d4b9d18b52617b1310b8c2397abe6b7.jar

       [dx] UNEXPECTED TOP-LEVEL EXCEPTION:
       [dx] java.io.FileNotFoundException: C:\Users\Tuukka\Documents\app\appcompat\bin\classes.jar (No such file or directory)

有确实是在应用程序兼容性\\ bin中没有classes.jar。事实上，在整个构建输出照看，似乎这样的事情从来没有建成，但蚂蚁似乎期望它的存在。

There is indeed no classes.jar in appCompat\bin. In fact, after looking through the entire build output, it seems such a thing was never built, yet Ant seems to expect that it exists.

有我丢失的东西吗？任何帮助将大大AP preciated。

Is there something I'm missing here? Any help would be greatly appreciated.

推荐答案

我觉得这个问题是由不被设置为库项目的项目造成的。如果你正在建立由专人一切你可以通过添加解决这个问题 android.library = TRUE 到 [项目] /appCompat/project.properties 文件。

I think this problem is caused by the project not being set up as a library project. If you are setting up everything by hand you can fix this by adding android.library=true to the [your project]/appCompat/project.properties file.
