在Android Studio中的错误内置本地库 - NDK-build.cmd完成了非零退出值2在Windows中执行问题

Question

我真的试图建立strongswan lib但在Windows机器。我按照从strongswan wiki所有步骤，但是当我试图打造的项目中，我得到这个错误。

我看到的问题是，NDK建造无法找到，但我真的确信NDK和SDK目录是正确的，仔细检查他们。

这里是我的build.gradle文件

   apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion '27.0.3'

    defaultConfig {
        applicationId "org.strongswan.android"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 62
        versionName "2.0.2"
    }

    sourceSets.main {
        jni.srcDirs = [] // disables the default ndk-build call (with on-the-fly Android.mk files)
        jniLibs.srcDir 'src/main/libs'
    }

    task buildNative(type: Exec) {
        workingDir 'src/main/jni'
        commandLine "${android.ndkDirectory}/ndk-build", '-j', Runtime.runtime.availableProcessors()
    }

    task cleanNative(type: Exec) {
        workingDir 'src/main/jni'
        commandLine "${android.ndkDirectory}/ndk-build", 'clean'
    }

    tasks.withType(JavaCompile) {
        compileTask -> compileTask.dependsOn buildNative
        options.compilerArgs << "-Xlint:unchecked" << "-Xlint:deprecation"
    }

    clean.dependsOn 'cleanNative'

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
    compileOptions {
        targetCompatibility 1.8
        sourceCompatibility 1.8
    }
}

dependencies {
    implementation 'com.android.support:appcompat-v7:26.0.2'
    implementation 'com.android.support:design:26.0.2'
    implementation 'com.android.support:preference-v7:26.0.2'
    implementation 'com.android.support:support-v4:26.0.2'
    testImplementation 'junit:junit:4.12'
}

编辑：

我看到的问题可以

        commandLine "${android.ndkDirectory}/ndk-build.cmd", '-C', Runtime.runtime.availableProcessors()

NDK建造必须NDK-build.cmd因为我使用Windows计算机。但是，当我改变此行中我得到这个错误：

Caused by: org.gradle.process.internal.ExecException: Process 'command 'C:\Users\kristiyan.varbanov\AppData\Local\Android\Sdk\ndk-bundle/ndk-build.cmd'' finished with non-zero exit value 2

Answer 1

我一直在寻找在堆栈跟踪，我看到的错误是摇篮want`s在文件夹中执行程序NDK建造：

C：\ Users \用户kristiyan.varbanov \桌面\ strongswan的\ src \前端\机器人\程序\ SRC \主\ JNI

正如你在gradle这个文件“任务buildNative”已配置。

您需要检查是否NDK建造是在指定的文件夹，但我相信你已经错误地配置了buildNative任务。
