Android 安卓工作室可以'；无法编译，但gradle cli可以编译

我在Mac上的Android Studio 0.5.7出现了奇怪的错误。我无法使用gradle和ndk build编译我的项目。它失败，出现以下错误：

FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':SKG:ndkBuild'.
A problem occurred starting process 'command 'ndk-build''

但是，当我从CLI运行./gradlew compileArmDebugJava时，项目已成功编译

android studio中的错误：

这是我的build.gradle文件：

import org.apache.tools.ant.taskdefs.condition.Os
apply plugin: 'android'

android {
    compileSdkVersion 16
    buildToolsVersion '19.0.3'


    defaultConfig {

        }
    }
    sourceSets.main {
        jniLibs.srcDir 'src/main/libs'
        jni.srcDirs = []
    }

    defaultConfig {
        ndk {

        }
        mips {

            }
        }
        arm {
            ndk {

        fat
    }
}


dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:19.+'
}

// call regular ndk-build(.cmd) script from app directory
task ndkBuild(type: Exec) {
    if (Os.isFamily(Os.FAMILY_WINDOWS)) {
        commandLine 'ndk-build.cmd', '-C', file('src/main').absolutePath
    } else {
        commandLine 'ndk-build', '-C', file('src/main/jni/').absolutePath
    }
}

tasks.withType(JavaCompile) {
    compileTask -> compileTask.dependsOn ndkBuild
}

---

已解决，删除了最后一行“/”，更改了此行：

commandLine 'ndk-build', '-C', file('src/main/jni/').absolutePath

为此：

commandLine 'ndk-build', '-C', file('src/main/jni').absolutePath 

---

如果你使用的是windows，你需要在gradle.build:

命令行ndkCommand，'-C'，file（'src/main/jni'）。绝对路径，'clean'

但如果您使用了其他操作系统，如Linux或Mac，则需要编写以下内容：

---

命令行ndkCommand，'-C'，file（'src/main/jni/'）。absolutePath，'clean'

您可以为自己的问题添加答案，而不是将其嵌入问题中，以使其他人更清楚地知道您找到了解决方案。当时，当我找到答案时，我无法回答我的问题，因为这样做我的分数很低。即使我将文件路径设置为没有尾随斜杠，我也会遇到同样的问题。你用什么系统？窗户？linux？对我来说，“libs/armeabi-v7a/libmylibrary.so”文件被生成到/jni/文件夹中，这是错误的，它应该在目录上。有没有办法在适当的文件夹中生成它们？用于回答您自己的问题。
