转自：http://www.cnblogs.com/raomengyang/p/4367620.html Android Studio报错：What went wrong:java.io.FileNotFoundException: /Users/raomengyang/Documents/workspace/fontmanager/.gradle/2.2.1/taskArtifacts/cache.properties (No such file or directory)> /Users/raomengyang/Documents/workspace/fontmanager/.gradle/2.2.1/taskArtifacts/cache.properties (No such file or directory) * Try:Run with –stacktrace option to get the stack trace. Run with –info or –debug option to get more log output. 1.项目中local.properties 的sdk.dir= <此处SDK路径不同需修改>2. Google一番没找到问题解决方法，cd 到Users/raomengyang/Documents/workspace/fontmanager/.gradle/2.2.1/ 后发现没有cache.properties文件，只有一个cache.properties.lock 感觉应该是这个文件被lock上了
➜ / cd Users/xxxxx(Username)/Documents/workspace/fontmanager
➜ fontmanager git:(temp) ✗ ls -a
. .gradle actionbarsherlock_new gradle local.properties.bak
.. .idea build gradlew local.properties.bak~HEAD
.git FontManage build.gradle gradlew.bat settings.gradle
.gitignore SliderLib fontmanager.iml local.properties viewpagerindicator
➜ fontmanager git:(temp) ✗ cd .gradle
➜ .gradle git:(temp) ✗ ls
2.2.1
➜ .gradle git:(temp) ✗ cd 2.2.1/taskArtifacts
➜ taskArtifacts git:(temp) ✗ ls
cache.properties.lock fileHashes.bin fileSnapshots.bin outputFileStates.bin taskArtifacts.bin
➜ taskArtifacts git:(temp) ✗ cache.properties.lock
于是cp cache.properties.lock /Users/raomengyang/Desktop然后把文件的读取改为everyone 读写，并去掉.lock后缀变为cache.properties再将其cp回去，项目成功运行。
