[gradle-user] exit value from exec command on windows - running subversion from gradle

[Sean Van Buggenum]

Hi all,

i'm looking for non-OS specific solution to my problem with windows and the
exit value on the exec command.

I had this problem previously, using gradle on windows, but then it was
solved brilliantly by a suggestion by a helpful user, Jesper Skov, who, when
he realized I wanted to run a gradle instance from gradle, suggested that I
use the Gradle Launcher. This worked perfectly. Not only did it solve my
problems on windows, but it was a general solution that allowed me to run my
gradle build script on linux (my native OS) as well.

Now I have this problem again, and can not solve it using the gradle
launcher, because it is not Gradle I am launching .... it is Subversion; see
here below

result = exec {
executable = 'svn'
 ignoreExitValue = true
args = ['info', "${svn_repo_root}/${projectLoc}/build.gradle",
 '--username', "${svn_user}", '--password', "${svn_pass}"]
}
 if (result.getExitValue()==0){
                                         // do something
                               }
                               else // do something else


Apparently (and I am no windows expert) I need to, if I want to get the exit
value from the exec command on windows, use the COMSPEC thingymagig.

%COMSPEC% /c svn

??

The problem with this is I don't just want to run this on windows, but on
linux as well (without having to modify the script each time).

Is there an OS transparent way of getting my exit value?

Alternatively, is there any way of getting gradle to tell you (a project
property or so) which OS you are currently running on?

Also, i'm not one for windows...

Can I count on this COMSPEC being present on windows? If I need to use it,
what syntax should I use, in the context of the 'exec' command on gradle.

thanks for any help!
