Question

我在运行Android Studio 3.3的Ubuntu 18.04上。我正在编写一个基本应用程序，以从android应用程序调用JNI函数。构建项目时，出现以下错误：

Process 'command '/home/pradeep/Android/Sdk/ndk-bundle/ndk-build'' finished with non-zero exit value 2

这是我的build.gradle文件。此处给出的ndk-build路径正确。

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.ndktest"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner 
"android.support.test.runner.AndroidJUnitRunner"
    }

    sourceSets.main {
        jni.srcDirs = [] //disable automatic ndk-build call
    }
    task ndkBuild(type: Exec, description: 'Compile JNI source via NDK') {
        commandLine '/home/pradeep/Android/Sdk/ndk-bundle/ndk-build',
                'NDK_PROJECT_PATH=build/intermediates/ndk',
                'NDK_LIBS_OUT=src/main/jniLibs',
                'APP_BUILD_SCRIPT=src/main/jni/Android.mk',
                'NDK_APPLICATION_MK=src/main/jni/Application.mk'
    }
    tasks.withType(JavaCompile) {
        compileTask -> compileTask.dependsOn ndkBuild
    }

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

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

这是错误消息：

如何解决？

处理'command'/ home / pradeep / Android / Sdk / ndk-bundle / ndk-build'完成，退出值非零2
