问题描述

我已经安装并设置了最新版本的 Android Studio(0.3.6，11 月 14 日发布)，但是在尝试构建我的项目(使用 Android Studio 新项目向导制作的基本 hello world 项目)时，我得到了以下错误:

I've installed and setup the latest version of Android Studio (0.3.6, nov 14 release) but upon trying to build my project (a bare-bones hello world project made with the Android Studio new project wizard) I get the following error:

BUILD FAILED

Total time: 5.923 secs

之后，我收到此错误:

Gradle: Execution failed for task ':Test2:dexDefaultFlavorDebug'.
> Could not call IncrementalTask.taskAction() on task ':Test2:dexDefaultFlavorDebug'

所以，看起来文件名、目录名或卷标语法"有问题，但是什么文件?什么目录?

So, it looks like something is wrong with the "The filename, directory name, or volume label syntax" but what file? What directory?

我猜这可能与分隔符有关，但我不确定，而且我对 gradle 的掌握很弱.

I'm guessing it might be something about the separator characters, but I'm not sure and my grasp of gradle is quite weak.

(我已将路径变量、JAVA_HOME 变量和 JDK_HOME 变量设置为指向我的 JDK 7_45 目录.我正在运行 Win 7.)

(I have set the path variable, JAVA_HOME variable and JDK_HOME variable to point to my JDK 7_45 directory. I'm running Win 7.)

我的 Gradle 文件看起来像这样

My Gradle file looks like this

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 17
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 17
        targetSdkVersion 17
    }
    buildTypes {
        release {
            runProguard true
            proguardFile getDefaultProguardFile('proguard-android-optimize.txt')
        }
    }
    productFlavors {
        defaultFlavor {
            proguardFile 'proguard-rules.txt'
        }
    }
}

dependencies {
}

推荐答案

终于解决了.我再次查看错误信息并尝试运行失败前的最后一条命令，例如:

Finally solved it. I looked at the error message again and tried to run the last command before failure, e.g.:

C:\Android\android-studio2\sdk\build-tools\android-4.4\dx.bat --dex --ou
tput E:\Backups\etc\TestProj2\Test2\build\libs\Test2-defaultFlavor-debug.dex E:\
Backups\etc\TestProj2\Test2\build\classes\defaultFlavor\debug E:\Backups\etc\Tes
tProj2\Test2\build\dependency-cache\defaultFlavor\debug

这给出了文件名、目录名或卷标语法不正确."然后我转到 build-tools 文件夹并运行 dx.bat 没有 cmd-line 参数:

This gave the "The filename, directory name, or volume label syntax is incorrect." So then I went to the build-tools folder and ran dx.bat with no cmd-line args:

C:\Android\android-studio2\sdk\build-tools\android-4.4\dx.bat

还是出现同样的错误.所以我查看了文件内部，发现了以下几行:

And still got the same error. So I took a look inside the file and found these lines:

rem Check we have a valid Java.exe in the path.
set java_exe=
if exist    "%~dp0..\tools\lib\find_java.bat" call    "%~dp0..\tools\lib\find_java.bat"
if exist "%~dp0..\..\tools\lib\find_java.bat" call "%~dp0..\..\tools\lib\find_java.bat"
if not defined java_exe goto :EOF

所以我尝试从命令行运行 find_java.bat，它什么也没返回.

So I tried running find_java.bat from the command line and it returned nothing.

所以我用下面的替换了上面的行:

So I replaced the above lines with the below one:

set java_exe=C:\Windows\System32\java.exe

一切都开始工作了......

And everything started working...
