IOS：createIPA gradle這個任務失敗，錯誤在HfsCompressor.compressNative

Question

當在命令行建設我libGDX遊戲的iOS，使用./gradlew ios:createIPA，我有時會收到以下錯誤：

... 
: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))`

FAILURE: Build failed with an exception. 

* What went wrong: 
Execution failed for task ':ios_lite:createIPA'.

* 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提供更多輸出，但沒有更多有用的信息，並且--stacktrace只顯示了Gradle中的內部堆棧跟蹤。

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

是什麼導致了這個錯誤，我該如何解決？

Answer 1

我仍然不知道是什麼導致它（在這方面更好的答案），但我找到了一個解決方法：重新啓動Gradle守護進程。大樓前，只需運行：

$ ./gradlew --stop 

守護程序會自動重新啓動下一個版本。到目前爲止，這種解決方法已經可靠地解決了我的錯誤。
