转换输出文件E：\ NewJoystick \ mavlink \ build \ libs \ ndk-libs.jar不存在

Question

没有mavlink / build / libs libs文件也不存在ndk-libs.jar也不存在！我怎么解决这个问题？我改变了路径，路径也正确我认为但是我做了sdk配置和同步，清理项目重建项目仍然存在同样的错误。有人可以帮忙吗？

这是我的local.properties文件代码

ndk.dir=C\:\\Users\\X\\AppData\\Local\\Android\\Sdk\\ndk-bundle
sdk.dir=C\:\\Users\\X\\AppData\\Local\\Android\\Sdk
gst.dir=C\:\\Users\\X\\Desktop\\gstolayi

这是我的build.gradle模块：mavlink

    buildToolsVersion '27.0.3'
    defaultConfig {
        minSdkVersion 21
