How do I run a PowerShell command from groovy the same way as "cmd /c <command>".execute()?

Use the -command parameter:

powershell -command "dir"

You can use the List form:

['powershell', '-command', 'dir'].execute()

I used a Groovy class to execute a PowerShell script. This is a little more elaborate than just executing a command, but I thought it might be helpful.

import groovy.util.logging.Log4jimport org.springframework.stereotype.Component@Component@Log4jclass PowerShellUtil {    def exec(debug, command, args){        def powerShellCommand = ".\\${command} ${args}"        def shellCommand = "powershell.exe -ExecutionPolicy Bypass -NoLogo -NonInteractive -NoProfile  -Command \"${powerShellCommand}\""        if (debug) log.debug powerShellCommand        def process = shellCommand.execute()        def out = new StringBuffer()        def err = new StringBuffer()        process.consumeProcessOutput(out, err)        process.waitFor()        if(out.size() > 0 && debug) log.debug out        if(err.size() > 0) log.error err    }}

Then I can execute the script with:

PowerShellUtil psUtil = new PowerShellUtil()psUtil.exec(true, 'script.ps1','script-args')
