git.exe is not found by gradle

Question

My Android Studio project uses git from gradle :

branchName = ByteArrayOutputStream().use { outputStream ->
                    exec {
                        commandLine("git branch --show-current")
                        standardOutput = outputStream
                    }
                    outputStream.toString()
                }

On Linux and Mac, this works just fine, but on Windows it says:

Could not start 'git'

and I have to replace it with this :

commandLine("cmd", "/c", "git branch --show-current")

this defeats the purpose for me since I want this to work on different platforms and machines. If I add it it'll instead break on Linux and Mac. any suggestions on what should I do ?

Answer 1

You can probably do an OS checking this way

import org.apache.tools.ant.taskdefs.condition.Os

// ...

branchName = ByteArrayOutputStream().use { outputStream ->
                    exec {
                        if (Os.isFamily(Os.FAMILY_WINDOWS)) commandLine("cmd", "/c", "git branch --show-current")
                        else commandLine("git branch --show-current")
                        standardOutput = outputStream
                    }
                    outputStream.toString()
                }
