Java - 在同一 shell 中逐行执行命令

Question

我是 Talend Open Studio 的 Java 新手。我想知道是否可以使用“Import-Module ActiveDirectory”执行 powershell.exe，然后启动动态命令，而无需使用“Import-Module ...”重新加载 powershell。

我知道这行不通，但我的想法可以这样翻译:

Runtime.getRuntime().Exec("powershell.exe");
Runtime.getRuntime().Exec("Import-Module ActiveDirectory");
Runtime.getRuntime().Exec("Get-ADUser TestLogin1");
Runtime.getRuntime().Exec("Set-ADUser -Identity TestLogin1 -Company MyCompany1");
Runtime.getRuntime().Exec("Get-ADUser TestLogin2");
Runtime.getRuntime().Exec("Set-ADUser -Identity TestLogin2 -Company MyCompany2");

为了让它发挥作用，我必须做......

Runtime.getRuntime().Exec("powershell.exe /c Import-Module ActiveDirectory ; Get-ADUser TestLogin");
Runtime.getRuntime().Exec("powershell.exe /c Import-Module ActiveDirectory ; Set-ADUser -Identity TestLogin1 -Company MyCompany1");
Runtime.getRuntime().Exec("powershell.exe /c Import-Module ActiveDirectory ; Get-ADUser TestLogin_2");
Runtime.getRuntime().Exec("powershell.exe /c Import-Module ActiveDirectory ; Set-ADUser -Identity TestLogin2 -Company MyCompany2");

我不想检查脚本文件，因为第一个更新命令 (Set-ADUser) 可能会对下一个更新命令产生影响。

谢谢。

我找到了一个使用 profesorfalken 的 jPowerShell 库的解决方案

https://github.com/profesorfalken/jPowerShell

//Creates PowerShell session (we can execute several commands in the same session)
   try (PowerShell powerShell = PowerShell.openSession()) {
       //Execute a command in PowerShell session
       PowerShellResponse response = powerShell.executeCommand("Import-Module ActiveDirectory");

       //Get an ADUser
       PowerShellResponse response = powerShell.executeCommand("Get-ADUser TestLogin1");
       //Print results ADUser
       System.out.println("PS : " + response.getCommandOutput());
       //Set an ADUser
       PowerShellResponse response = powerShell.executeCommand("Set-ADUser -Identity TestLogin1 -Company MyCompany1");

       //Get an ADUser
       PowerShellResponse response = powerShell.executeCommand("Get-ADUser TestLogin2");
       //Print results ADUser
       System.out.println("PS : " + response.getCommandOutput());
       //Set an ADUser
       PowerShellResponse response = powerShell.executeCommand("Set-ADUser -Identity TestLogin2 -Company MyCompany2");

   } catch(PowerShellNotAvailableException ex) {
       //Handle error when PowerShell is not available in the system
       //Maybe try in another way?
   }
