Gradle修改styles.xml后第二次构建失败

Gradle修改styles.xml后第二次构建失败

6

我已经将我的项目迁移到使用Gradle（使用旧的Android项目结构）。最近我将Android Studio升级到v0.2，这迫使我使用android gradle插件v0.5。我能够使用我定义的任何flavour来构建我的项目，无论是debug还是release。

以下是我遇到的问题：

- 执行gradlew clean - 执行gradlew assembleTestenvDebug - 此时Gradle输出：

“BUILD SUCCESSFUL”

- 修改styles.xml文件中的任何值 - 再次执行gradlew assembleTestenvDebug - 此时Gradle输出：

“/Users/myuser/Project/src/com/namespace/project/views/SomeCustomView.java:60: error: cannot find symbol mSize = arr.getInt(R.styleable.SomeCustomView_some_custom_styleable, 0);”

现在Gradle会抱怨我在attrs.xml中声明的每个自定义xml属性。这让我抓狂，因为每次修改styles.xml后都必须清理和重建我的项目。

请帮帮我。

谢谢！我的项目结构：

- Project
- . AndroidManifest.xml
- . assets/
- . build/
- . build.gradle
- . gen/
- . gradle/
- . gradle.properties
- . gradlew
- . libs (includes .jar files)
- . modules
- . . library_projectA
- . . library_projectB
- . out
- . project.properties
- . res

- . res_testenv
- . . values
- . . . strings.xml

- . res_prodenv
- . . values
- . . . strings.xml

- . settings.gradle
- . src/
- . . com/
- . . . namespace/
- . . . . android/

项目目录下的build.gradle文件：

task wrapper(type: Wrapper) {
    gradleVersion = '1.6'
}

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}

apply plugin: 'android'

dependencies {
    compile 'com.android.support:support-v4:13.0.0'
    compile fileTree(dir: 'libs', include: '*.jar')
    compile project(':modules:libprojectA')
    compile project(':modules:libprojectB')
}

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 10
        targetSdkVersion 17
    }

    signingConfigs {
        release {

        }
    }

    buildTypes {
        debug {
            runProguard false
        }

        alphaRelease {
            runProguard false
            zipAlign true
            signingConfig signingConfigs.release
        }

        release {
            runProguard true
            proguardFile 'proguard-project.txt'
            signingConfig signingConfigs.release
        }
    }

    productFlavors {
        testenv {}
        prodenv {}
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
            aidl.srcDirs = ['src']
        }

        testenv {}
        prodenv {}
    }

    android.sourceSets.testenv {
        res.srcDirs = ['res_test']
    }

    android.sourceSets.prodenv {
        res.srcDirs = ['res_prod']
    }
}

if (project.hasProperty('storeFile') && project.hasProperty('storePassword') &&
        project.hasProperty('keyAlias') && project.hasProperty('keyPassword')) {
    android.signingConfigs.release.storeFile = file(storeFile)
    android.signingConfigs.release.storePassword = storePassword
    android.signingConfigs.release.keyAlias = keyAlias
    android.signingConfigs.release.keyPassword = keyPassword
}

对于每个库项目，都需要编写相应的 build.gradle 文件：

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}

apply plugin: 'android-library'

dependencies {
    compile 'com.android.support:support-v4:13.0.0'
}

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 10
        targetSdkVersion 17
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            res.srcDirs = ['res']
        }
    }
}

附上堆栈跟踪：

你是在res文件夹中修改style.xml，还是在其他文件夹比如res_flavor1中进行修改？ - Joe

@Joe - 我正在修改主项目目录下的res/values/styles.xml，而不是任何风味。 - woot

我有一个理论，但我可能错了。

查看用户指南，我没有看到任何直接添加自定义源集的提及。这可能意味着构建系统不会检测源集（如testenv）的更改，除非它是一个风味或构建类型的一部分。

我会尝试将您的环境定义为一个风味组。不确定您的具体要求，但它可能看起来像这样：

flavorGroups "environment", "flavors"
productFlavors {
    testenv { 
        flavorGroup "environment"
    }

    prodenv {
        flavorGroup "environment"
    }

    flavorA {
        flavorGroup "flavors"
        ...
    }

    flavorB {
        flavorGroup "flavors"
        ...
    }

假设您需要一个可以由这两个构建组成的版本，例如app-flavor1-testenv-debug.apk。只是一个想法，我还没有测试过。

另外，如果您成功了，我建议迁移到新的布局。这样，您就可以依赖于src/main/res与src/testenv/res和src/debug/res（如果存在）合并的约定，甚至不必在build.gradle中提及它们。
