How to execute a command line process ? (tried with Exec but not worked)

Phuong_LuHoai · September 10, 2012, 8:19am

Hi,

Now I’m building Gradle in Cygwin in Windows 7 64bit. In Cygwin, I run the command successfully on a terminal: “gem install compass” I can use maven-exec-plugin to call that command in Maven.

But how should we call in Gradle ?

I have tried with Exec but not done successfully:

task installCompass(type:Exec) {
    commandLine 'gem', 'install', 'compass'
}

Thanks, Phuong.

Hey Phuong, Your snippet works fine on my machine. What error do you get? can you run gradle with “-i” to get more output? Do you have “gem” on your path?

cheers, René

Hi René,

I think “gem” is on path now because I can run that command everywhere in Cygwin’s terminal.

Below is the error when run with --info:

Process 'command 'gem'' finished with exit value -1 (state: FAILED)
  FAILURE: Build failed with an exception.
  * What went wrong:
Execution failed for task ':activation:prepareCss'.
> A problem occurred starting process 'command 'gem''

And with --debug: ( The PATH contains “gem” definitely.)

Can anybody help me ?

Peter_Niederwieser · September 17, 2012, 7:18am

If it works on the command prompt, it might be a compatibility issue with cygwin. From my personal experience, I would recommend to run Gradle from the command prompt rather than from cygwin.

Brandon_Barker · December 11, 2014, 9:34pm

The problem here is that some projects with native components may depend on Cygwin for their Windows builds. I verified this is still an issue. I intend to see if this ( https://github.com/derianto/Gradle-Cygwin-Toolkit-Plugin) helps, but it is old, and I’m a Gradle newbie trying to use Gradle for native projects, which seems to pose a number of obstacles.

Brandon_Barker · December 11, 2014, 9:42pm

Note the above plugin does not seem to help.
