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' }
