【中文标题】Gradle 构建不起作用：任务“：MyApp：compileDebug”执行失败【英文标题】：Gradle build not working: Execution failed for task ':MyApp:compileDebug' 【发布时间】：2014-01-31 11:42:58 【问题描述】：我正在尝试将项目迁移到 Gradle，但每次运行命令时都会引发异常
gradle build --stacktrace
我使用的是 Gradle 1.6。这是错误的堆栈跟踪：
:MyApp:compileDebug FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':MyApp:compileDebug'.
> Compilation failed; see the compiler error output for details.
* Try:
Run with --info or --debug option to get more log output.
* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':MyApp:compileDebug'.

我在 settings.gradle 中定义了以下结构：
include ':MyApp'
include ':Libraries:LibProject1'
include ':Libraries:LibProject2'
include ':Libraries:LibProject3'
include ':Libraries:LibProject4'
而我项目的目录是这样的：
- My Repository
-- settings.gradle
- My App
-- build.gradle
- Libraries
- LibProject1
-- build.gradle
- LibProject2
-- build.gradle
- LibProject3
-- build.gradle
- LibProject4
-- build.gradle
我的应用> build.gradle 文件是这样的：
buildscript
repositories
mavenCentral()
dependencies
classpath 'com.android.tools.build:gradle:0.5.+'
apply plugin: 'android'
dependencies
compile fileTree(dir: 'libs/main', include: '*.jar')
compile project(':Libraries:LibProject1')
compile project(':Libraries:LibProject2')
compile project(':Libraries:LibProject3')
compile project(':Libraries:LibProject4')
android
compileSdkVersion "Google Inc.:Google APIs:19"
buildToolsVersion "19.0.1"
sourceSets
main
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src/main/java', 'src-gen/main/java', 'generated']
resources.srcDirs = ['src']
aidl.srcDirs = ['src']
renderscript.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
而所有的LibProject#> build.gradle文件都是这样的：
buildscript
repositories
mavenCentral()
dependencies
classpath 'com.android.tools.build:gradle:0.5.+'
apply plugin: 'android-library'
android
compileSdkVersion 19
buildToolsVersion "19.0.1"
sourceSets
main
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src']
resources.srcDirs = ['src']
aidl.srcDirs = ['src']
renderscript.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
我已经尝试了在其他线程中找到的几种可能的解决方案，但似乎没有任何效果。
我还将我的项目结构及其所有 .gradle 文件与另一个正在成功构建的项目进行了比较，我找不到任何遗漏。
与我在相关线程中发现的其他问题不同，这里的堆栈跟踪似乎没有提供任何关于引发异常的具体原因。有什么想法吗？
【问题讨论】：
:MyApp:compileDebug 因编译错误而失败，并且应该在某处出现编译器错误消息。 （您不必使用--debug 或--stacktrace 来获取该消息。）
@PeterNiederwieser 我找不到任何编译器错误消息。我得到的只是Execution failed for task ':MyApp:compileDebug'. > Compilation failed; see the compiler error output for details. * Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. 在哪里可以获得更详细的编译器消息？
请问您为什么不使用更新版本的插件？ Android-Gradle 插件现在为 0.7.4，Gradle 为 1.9 - 并不是说这对您遇到的问题有影响，但它可能会。
编译器错误消息将在您显示的消息上方的某个位置。对于您的升级问题，请参阅 SO 上的类似问题。
在 build.gradle（文件中的第 6 行）中，您需要将插件的类路径更改为“com.android.tools.build:gradle:0.7.+”。这应该会导致插件寻找正确的 Gradle 版本（对于插件 - 1.9）。
【参考方案1】：
如果您不使用 Android Annotations 但仍然看不到原因，您实际上可以按照消息中的说明执行操作（检查编译器输出），方法是：
转到构建选项卡 将输出切换到编译器输出【讨论】：
哪天我会遇到错误，却不知道有这个出色的按钮，谢谢！ 我为 Android 开发已经 7 年了，但是每次我遇到问题时，我都不关心这个按钮，谢谢【参考方案2】：我终于找到了问题所在。该项目使用 Android Annotations，我已将其生成的源文件夹包含在我的 build.gradle 文件中。
当 Gradle 再次尝试生成源时，会因为类重复而失败。
这是正确的 build.gradle：
buildscript
repositories
mavenCentral()
dependencies
classpath 'com.android.tools.build:gradle:0.5.+'
apply plugin: 'android'
dependencies
compile fileTree(dir: 'libs/main', include: '*.jar')
compile project(':Libraries:LibProject1')
compile project(':Libraries:LibProject2')
compile project(':Libraries:LibProject3')
compile project(':Libraries:LibProject4')
android
compileSdkVersion "Google Inc.:Google APIs:19"
buildToolsVersion "19.0.1"
sourceSets
main
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src/main/java', 'src-gen/main/java']
resources.srcDirs = ['src']
aidl.srcDirs = ['src']
renderscript.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
【讨论】：
对不起，这个 Gradle 文件的主要区别是什么？ @IgorGanapolsky'generated' 文件夹不包含在java.srcDirs 中。
有趣。我遇到了同样的问题，我正在使用 AA，但我在 srcDirs 中没有“生成”文件夹。
@FelipeBari src-gen 是什么？
@IgorGanapolsky 这是一个由其他东西自动生成的类的文件夹。在我的例子中，它存储了所有由 greenDAO 创建的数据库类。以上是关于Gradle 构建不起作用：任务“：MyApp：compileDebug”执行失败的主要内容，如果未能解决你的问题，请参考以下文章
