Gradle构建不起作用：任务执行失败'：MyApp：compileDebug'

Question

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

我正在使用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'

我的项目目录是这样的：

- 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＆gt; 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']
        }
    }
}

所有LibProject＃＆gt; build.gradle文件是这样的：

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']
        }
    }
}

我已经尝试过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文件与另一个成功构建的项目进行了比较，但我找不到任何遗漏。

与我在相关线程中发现的其他问题不同，此处的堆栈跟踪似乎没有提供有关引发异常的具体原因。有什么想法吗？

Answer 1

我终于找到了问题所在。该项目使用Android Annotations，我已将其生成的sources文件夹包含在我的build.gradle文件中。

当Gradle再次尝试生成源时，由于重复的类，它会失败。

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']
        }
    }
}

Answer 2

如果您不使用Android Annotations，但仍然看不到原因，则可以通过以下方式实际执行消息中的内容（检查编译器输出）：

• 转到“构建”标签

• 切换到编译器输出
