ios:createIPA gradle 任务因 HfsCompressor.compressNative 错误而失败

Question

从命令行使用 ./gradlew ios:createIPA 构建 iOS 的 libGDX 游戏时，有时会收到以下错误：

...
:ios_lite:createIPA
RoboVM has detected that you are running on a slow HDD. Please consider mounting a RAM disk.
To create a 2GB RAM disk, run this in your terminal:
SIZE=2048 ; diskutil erasevolume HFS+ 'RoboVM RAM Disk' `hdiutil attach -nomount ram://$((SIZE * 2048))`

:ios_lite:createIPA FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':ios_lite:createIPA'.
> org.robovm.compiler.util.io.HfsCompressor.compressNative(Ljava/lang/String;[BI)Z

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

--info 和 --debug 提供更多输出，但没有更多有用信息，--stacktrace 仅显示 Gradle 中的内部堆栈跟踪。

使用 Gradle 2.2、OS X 10.11.5、JVM 1.8.0_74、RoboVM 1.12.0。

是什么导致了这个错误，我该如何解决？

Answer 1

我仍然不知道是什么原因造成的（欢迎在这方面提供更好的答案），但我找到了一种解决方法：重新启动 Gradle 守护程序。在构建之前，只需运行：

$ ./gradlew --stop

守护程序将自动重新启动以进行下一次构建。到目前为止，这个解决方法已经可靠地为我修复了错误。
