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），但在试图构建我的项目（一个用Android Studio新项目向导制作的光秃秃的hello world项目）时，我得到了以下错误。

在这之后，我得到这个错误。


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

所以，看起来是 "文件名、目录名或卷标语法 "出了问题，但什么文件？什么目录？


我猜这可能是关于分隔符的问题，但我不确定，而且我对gradle的掌握相当薄弱。


(我已经设置了路径变量、JAVA_HOME 变量和 JDK_HOME 变量，以指向我的 JDK 7_45 目录。我运行的是Win 7）。


编辑：我的Gradle文件看起来像这样


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 {

终于解决了。我又看了看错误信息，试着运行失败前的最后一条命令，例如。 

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

这就出现了 "文件名、目录名或卷标的语法不正确"。于是我去了build-tools文件夹，运行dx.bat，没有cmd-line args。


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

但仍然得到同样的错误。所以我看了一下文件，发现了这几行。


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

所以我试着从命令行运行find_java.bat，结果发现it returned nothing.


所以我用下面这句话代替了上面这句话。


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

一切都开始工作了...
ChiefTwoPencils ：
这不亚于一项伟大的工作。拍拍你自己的背!
Gorkamorka ：
谢谢！@ChiefTwoPencils 谢谢!如果我能提供帮助，我很高兴。

Here is my solution:

我在运行我的React Native应用时遇到这个错误。 

java.io.IOException: The filename, directory name, or volume label syntax is incorrect.

这意味着你在Gradle中出现了问题。然后我去了build-tools文件夹，运行了dx.bat，没有cmd-line args


C:\Android\build-tools\30.0.1\dx.bat

(位于Sdk中）。


用记事本或任何编辑器或IDE打开这个文件。你在哪里找到下面这行代码


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

用下面的代码替换这个代码。
