Error:Execution failed for task ‘:app:buildNative’. > A problem occurred starting process ‘command ‘C:\NDK/ndk-build”

运行有native库调用的项目，出现该错，原build文件中，task代码如下

task buildNative(type: Exec, description: 'Compile JNI source via NDK') {        def ndkDir = android.ndkDirectory        commandLine "$ndkDir/ndk-build",                '-C', file('src/main/jni').absolutePath, // Change src/main/jni the relative path to your jni source                '-j', Runtime.runtime.availableProcessors(),                'all',                'NDK_DEBUG=0'    }    task cleanNative(type: Exec, description: 'Clean JNI object files') {        def ndkDir = android.ndkDirectory        commandLine "$ndkDir/ndk-build",                '-C', file('src/main/jni').absolutePath, // Change src/main/jni the relative path to your jni source                'clean'    }

因为windows操作环境下， commandLine “ndkDir/ndk−build",这句指令是错误的，需要加上后缀为：commandLine"ndkDir/ndk-build.cmd”,修改后代码如下：

task buildNative(type: Exec, description: 'Compile JNI source via NDK') {        def ndkDir = android.ndkDirectory        commandLine "$ndkDir/ndk-build.cmd",                '-C', file('src/main/jni').absolutePath, // Change src/main/jni the relative path to your jni source                '-j', Runtime.runtime.availableProcessors(),                'all',                'NDK_DEBUG=0'    }    task cleanNative(type: Exec, description: 'Clean JNI object files') {        def ndkDir = android.ndkDirectory        commandLine "$ndkDir/ndk-build.cmd",                '-C', file('src/main/jni').absolutePath, // Change src/main/jni the relative path to your jni source                'clean'    }
