Android Studio 无法编译，但 gradle cli 可以编译答案

【问题标题】：Android Studio can't compile, but gradle cli CAN compileAndroid Studio 无法编译，但 gradle cli 可以编译

【问题描述】：

我在 Mac 上使用 Android Studio 0.5.7 时出现奇怪错误。我无法使用 gradle 和 ndk-build 编译我的项目。它失败并出现此错误：

FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':SKG:ndkBuild'.
A problem occurred starting process 'command 'ndk-build''

但是，当我从 CLI 运行 ./gradlew compileArmDebugJava 时，项目编译成功。

android studio 中的错误：

【问题讨论】：

您可以为自己的问题添加答案，而不是将其嵌入问题中，以便其他人更清楚您找到了解决方案。
当时，当我弄清楚时，我无法回答我的问题，因为我的分数很低。
即使我将文件路径设置为没有尾部斜杠，我也遇到了同样的问题。嗯。
你用什么系统？窗户？ linux ?
对我来说，“libs/armeabi-v7a/libmylibrary.so”文件生成到 /jni/ 文件夹中，这是错误的，它应该在目录上。有没有办法在正确的文件夹中生成它们？

【解决方案1】：

已解决，删除了最后一个“/”，从这里更改了一行：

commandLine 'ndk-build', '-C', file('src/main/jni/').absolutePath

到这里：

commandLine 'ndk-build', '-C', file('src/main/jni').absolutePath

【讨论】：

回答您自己的问题。

【解决方案2】：

如果你使用的是 windows，你需要在 gradle.build 中写下这个：commandLine ndkCommand,'-C', file('src/main/jni').absolutePath,'clean'

但如果你使用其他操作系统，如 Linux 或 Mac，你需要这样写： commandLine ndkCommand,'-C', file('src/main/jni/').absolutePath,'clean'
