在 ubuntu 12 上，我正在尝试运行 fuse-jna 的示例程序.我收到以下错误消息

On ubuntu 12, I am trying to run example program of fuse-jna. I got below error message

syed@ubuntu:~/Downloads/fuse-jna-master/examples$ ./hellofs.sh ~/hellofs
:compileJava FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':compileJava'.

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

BUILD FAILED

运行 java -version 命令显示我:

syed@ubuntu:~/Downloads/fuse-jna-master/examples$ java -version
java version "1.7.0_15"
OpenJDK Runtime Environment (IcedTea7 2.3.7) (7u15-2.3.7-0ubuntu1~12.10)
OpenJDK Client VM (build 23.7-b01, mixed mode, sharing)

javac -version 的输出:

syed@ubuntu:~/Downloads/fuse-jna-master/examples$ javac -version

推荐答案

这是环境变量的问题.更正etc/environment中的java_home环境变量，重启ubuntu后，运行正常.谢谢指导.

It was a problem with an environment variable. After correcting the java_home environment variable in etc/environment and restarting ubuntu, now it runs ok. Thanks for the guidance.
