升级Android studio 3.0后，externalNativeBuildRelease出现依赖错误

Question

在 2.3.3 上，构建运行良好，但是在升级 3.0.0 后出现此问题。有谁能帮助我吗？ 原因是没有生成libSDL2.so，但是我不明白为什么SDLActivity模块在SDL2-android-studio完成构建之前就开始构建。

我认为 SDLActivity 模块在 SDL2-android-studio 模块的构建作业完成后开始构建。事实上，在 2.3.3 上，它起作用了。但是，在 3.0.0 上，它没有。也就是说，在 2.3.3 上，SDLActivity 的任务 externaNativeBuildRelease 在 SDL-android-studio 的任务完成之后开始。在 3.0.0 上，在 SDL-android-stduio-studio 的任务 transformClassesAndResourcesWithPrepareIntermediateJasrForDebug 之后，处理所有的 SDLActivity。 如何控制任务之间的依赖关系？

提前致谢。

SDL2 模块的 build.gradle 如下所示。

apply plugin: 'com.android.library' 

android 
{
    compileSdkVersion 26
    buildToolsVersion '26.0.2'

    defaultConfig {
        minSdkVersion 21
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"

        ndk {
            abiFilters 'x86', 'armeabi-v7a', 'arm64-v8a'
        }
        externalNativeBuild {
            cmake {
                arguments '-DANDROID_TOOLCHAIN=clang'
            }

        }
    }

    externalNativeBuild {
        cmake {
            path 'android-cmake/CMakeLists.txt'
        }
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'),
                    'proguard-rules.pro'
        }
        debug {
            jniDebuggable true
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
}

而且，SDLActivity 的 build.gradle 如下所示。

apply plugin: 'com.android.library'

android {
    compileSdkVersion 26
    buildToolsVersion '26.0.2'

    defaultConfig {
        minSdkVersion 21
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"

        ndk {
            abiFilters 'x86', 'armeabi-v7a', 'arm64-v8a'
        }
        externalNativeBuild {
            cmake {
                arguments '-DANDROID_TOOLCHAIN=clang',
                        '-DANDROID_PLATFORM=android-21'
                cppFlags "-std=c++11"
            }

        }
    }

    externalNativeBuild {
        cmake {
            path 'CMakeLists.txt'
        }
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        debug {
            jniDebuggable true
        }
    }

}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:26.+'
    androidTestCompile 'junit:junit:4.12'
    testCompile 'junit:junit:4.12'
    compile project(':SDL2-android-studio')
    compile project(':libtciplayer')
    compile project(':TciSdk')
    compile project(':soundtouch')
}
