android - 创建创建输出jar的自定义gradle项目时出现问题

Question

我目前有一个自定义的build.gradle，它可以cmake并构建一个SWIG c++项目并生成一个jar文件供我的android项目使用。 ( jar 在cmake内生成)

我当前的设置大部分都可以使用。 jar文件已正确链接到我的android项目，并且构建良好。我唯一的问题是android studio无法识别该库。没有自动完成功能在起作用，它强调了将我的媒体库的所有使用作为错误。

C++项目build.gradle

task cmakeMyLibrary(type: Exec) {
     inputs.file 'CMakeLists.txt'
     outputs.file 'Makefile'

     ext.jarFile = new File(parent.buildDir, "mylibrary.jar")

     commandLine 'cmake' ...
}

task makeMyLibrary(type: Exec, dependsOn: cmakeMyLibrary) {

    inputs.dir '.'

    outputs.file cmakeMyLibrary.jarFile

    commandLine 'make', '-j10'
}

task cleanMyLibrary(type: Exec) {
     commandLine 'make', 'clean'
}

configurations.create('default')
artifacts {
    it."default"(cmakeMyLibrary.jarFile) {
        builtBy makeMyLibrary
    }
}

android项目build.grade

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.7.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 19
    buildToolsVersion "18.1.1"

    defaultConfig {
        minSdkVersion 10
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:+'
    compile project(':mylibrary')
}

每次我执行“使用gradle文件同步项目”时，都会得到一个异常(exception):

Gradle 'MyApplication6' project refresh failed:

当我查看gradle源时，似乎断言传递给getModuleName的路径为空。

可能无法帮助您回答问题，但请确保从18.1.1和0.7。+升级到Build Tools 19.0.1和Android Gradle插件0.8.1(或最新版本)。过去使用gradle / IntelliJ时，存在一些由旧版本的bug引起的错误。您将要确保Gradle包装器最多为0.10，但是IntelliJ会提示您有关情况。

也许发布更多有关您的项目结构的信息...或者由于已经过去了一个多月，请告诉我们您是否已找到解决方法... :)
