Question

我尝试将原生调试添加到Android Studio NDK项目的项目中。在过去，我只是使用gradle来启动一个shell脚本，它构建了NDK lib。现在我试图使用gradle-experimental插件。

我已经在网上搜索了一些信息，（主要是Android Tools Site - Gradle Experimental），关于使用NDK的gradle-experimental和我把这个版本放在一起.gradle文件，它使用预览NDK支持，使用Java构建内联进行NDK构建。

最终通过各种信息将这些内容整合在一起后，我设法建立了NDK部分，但现在它无法包含明确包含在依赖项中的httpmime-4.4-beta1.jar文件，并且我尝试了很多不同的排列，例如：

compile files("libs/httpmime-4.4.jar")

但无论如何，Jar文件中缺失符号的错误仍然会出现。

出于沮丧，我切换回非实验分支，即使使用旧的build.gradle文件，它现在也无法找到相同的jar文件。这是Android Studio 2.0 Preview 6的一个问题吗？

有没有其他人经历过这个，或者有解决方案？最终在Android Studio中进行NDK调试工作会非常方便，如果它不是最后一道障碍，我想我会在那里。

如果没有重新编写依赖于该jar文件的代码，我将无法尝试其他什么。我也对上面的build.gradle文件的格式提出了建议，因为这些新功能的文档仍然非常稀疏，并且一些示例似乎已经过时关于正确的语法。

我错过了什么？

你可以看到C和Cpp（mobile：compileNativeArmeabiDebugArmSharedLibraryNativeMainCpp）步骤正常发生，但Javac失败了。对于来自apache的http-mime lib，这种jar文件方法在过去的2年左右都运行良好，所以我不明白为什么突然这是一个问题。

是的，我知道apache libs已被弃用，但这是遗留代码，尽管如此，它仍然可以使用，并且将来会更新。

执行此操作的一般方法包括您在依赖项中查找的内容。编译fileTree（dir：＆＃39; libs＆＃39;，include：[＆＃39; * .jar＆＃39;]）

但是，我不确定能否解决这个问题。我总是把jar放在目录结构顶部的libs目录中。如果您需要将jar放在不同的位置，那么这对我有用：

repositories {
    flatDir {
        dirs '<relativePathToJar>'
    }
}

model { ... }

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

使用gradle-experimental插件进行NDK调试
