Execute shell script in Gradle
I have a gradle build setup at the beginning of which I want to execute a shellscript in a subdirectory that prepares my environment.
task build << {
}
task preBuild << {
println 'do prebuild stuff:'
}
task myPrebuildTask(type: Exec) {
workingDir "$projectDir/mySubDir"
commandLine './myScript.sh'
}
build.dependsOn preBuild
preBuild.dependsOn myPrebuildTask
However, when I execute the task either by calling gradle myPrebuildTask
or by simply building the project, the following error occurs:
> A problem occurred starting process 'command './myScript.sh''
Unfortunately, thats all I get.
I have also tried the following - same error.
commandLine 'sh mySubDir/myScript.sh'
I use Gradle 1.10 (needed by Android) on Windows, inside a Cygwin shell. Any ideas?
Solution 1:
use
commandLine 'sh', './myScript.sh'
your script itself is not a program itself, that's why you have to declare 'sh' as the program and the path to your script as an argument.
Solution 2:
A more generic way of writing the exec task, but portable for Windows/Linux, if you are invoking a command file on the PATH:
task myPrebuildTask(type: Exec) {
workingDir "$projectDir/mySubDir"
if (System.getProperty('os.name').toLowerCase(Locale.ROOT).contains('windows')) {
commandLine 'cmd', '/c', 'mycommand'
} else {
commandLine 'sh', '-c', 'mycommand'
}
}
This doesn't directly address the use case for the OP (since there is script file in the working directory), but the title of the question is more generic (and drew me here), so it could help someone maybe.
Solution 3:
unfortunately options with commandLine not worked for me in any way and my friend find other way with executable
executable "./myScript.sh"
and full task would be
task startScript() {
doLast {
exec {
executable "./myScript.sh"
}
}
}
