You can also use the WSL on recent Windows and call the wsl shell, which
can be call with:
“wsl ${cmd}”
I made myself a function that do call the proper shell based on the current
platform, so my pipeline script does look like a big if else mess for each
shell command, on windows it append the wsl in front of my command and fix
the stdout return value.
Here is some groovy scripts function I do inject to “fix” (or if you prefer
bring it to human decent version of command) the shell:
*/**
** Console cross platform command*
**/*
def BasicConsole(labelStr, cmd, returnStatus = *false*, returnStdout =
*false*, useWsl = *false*) {
*// Only good for exact same syntax command on all platform or use wsl
to execute the command into unix like under Windows if this is available*
*if*(isUnix()) {
*return*
sh(label: labelStr, script: cmd, returnStatus: returnStatus, returnStdout:
returnStdout);
} *else* {
*return*
WindowFixReturn(bat(label: labelStr, script: WindowFixCmd(cmd, useWsl),
returnStatus: returnStatus, returnStdout: returnStdout), returnStdout);
}
}
def ConsoleVar(varName) {
*if*(isUnix()) {
*return* "\${${varName}}";
} *else* {
*return* "%${varName}%";
}
}
def WindowFixReturn(data, returnStdout) {
*if*(returnStdout) {
*// Remove the requested command echo into the shell, this make the
behavior more closer to unix for cross platform behavior*
*return* data.trim().readLines().drop(1).join("\n");
}
*return* data;
}
def WindowFixCmd(cmd, useWsl) {
*if*(useWsl) {
*return* WindowsWslCommand(cmd);
}
*return* cmd;
}
def WindowsWslCommand(cmd) {
*return* "wsl ${cmd}";
}
def WindowsEscapeVarPercentage(str) {
*if*(isUnix()) {
*return* str;
}
*// If we want literal %*
*return* str.replace("%", "%%");
}
def ConsoleScriptExtension() {
*if*(isUnix()) {
*return* ".sh";
} *else* {
*return* ".bat";
}
}
def ConsoleCommandDelimiter() {
*// When doing command that must be execute no matter the results of
the first one*
*if*(isUnix()) {
*return* ";";
} *else* {
*return* "&";
}
}
I did some file manipulation commands for files and folders manip (delete,
create, exist, etc) some my pipeline scripts now run the same code on all
platform without issues and remove the big if(isWindows()) mess all around.
Wish they have made this build in. This is a CI, this is what it should do
manipulated files in many env. Feel like this is lacking big time.
If you want to detect the main platform for the 3 majors OS and you need to
determine which one it is:
*/**
** Platform specific check*
**/*
def GetOS() {
*if*(isUnix()) {
def uname = sh(script: 'uname', returnStdout: *true*);
*if*(uname.startsWith("Darwin")) {
*return* "MacOS";
}
*// TODO godboutj 2019-07-30, Add other *nix check here*
*return* "Linux";
}
*return* "Windows";
}
def IsMacOS() {
*return* GetOS() == "MacOS";
}
def IsLinux() {
*return* GetOS() == "Linux";
}
def IsWindows() {
*return* GetOS() == "Windows";
}
Then you can manipulate the path:
*/**
** Path Manipulation*
**/*
def ToWindowsPath(path) {
*return* path.replace("/", "\\");
}
def ToUnixPath(path) {
*return* path.replace("\\","/");
}
def ToNativePath(path) {
*if*(isUnix()) {
*return* ToUnixPath(path);
}
*return* ToWindowsPath(path);
}
This allow for very simple scripts and make it bearable to work with the
Jenkins API.
