Question

我正在尝试将实际运行java语句的.bat文件转换为PowerShell脚本，主要是因为.bat文件的用户/密码是硬编码的，而且

set /p password="Enter password: " %=%

没有从命令提示符中隐藏密码。

java命令在我从.bat文件或直接从dos提示符运行时以及从.bat文件运行时运行正常。

我确保所有环境变量都在批处理文件中设置。

我的问题在于以下内容：

当我从命令行或直接从命令提示符运行它时，java工作正常，

当我尝试运行使用cmd.exe / c直接运行该行时不起作用，如果我从powershell调用.bat文件它不起作用并给出以下错误。

cmd : java.lang.NoClassDefFoundError

我不明白...为什么手动我可以运行并通过PowerShell脚本它不起作用？

这是我的.BAT文件，运行正常：

@rem ###################################
set IIQPATH=C:\IIQ\IIQ
set exportpath=C:\EXPORT
set /p userid="Enter ID: " %=%
set /p password="Enter password: " %=%
@rem ##################################
echo %exportpath%
set CLASSPATH=%CLASSPATH%;%IIQPATH%\WEB-INF\classes
set CLASSPATH=%CLASSPATH%;%IIQPATH%\WEB-INF\lib\identityiq.jar
set CLASSPATH=%CLASSPATH%;%IIQPATH%\WEB-INF\lib\sqljdbc4.jar
set CLASSPATH=%CLASSPATH%;./split

@rem Export the objects

java sailpoint.launch.Launcher console iiqBeans -u %userid% -p %password% -c "export -clean %exportpath%\Application.xml Application"

这是我的PowerShell代码

$iiquser = Read-Host 'Provide User for'$target2' environment'
$iiqpass = Read-Host 'Provide Password?' -AsSecureString
$actualdate=Get-Date -format MM_dd_yyyy
$iiquser
$iiqpass

Push-Location C:\EXPORT

$env:IIQPATH="C:\IIQ\IIQ"
$env:exportpath="C:\EXPORT"
Remove-Item env:CLASSPATH
$env:CLASSPATH="$env:CLASSPATH;$env:IIQPATH\WEB-INF\classes"
$env:CLASSPATH="$env:CLASSPATH;$env:IIQPATH\WEB-INF\lib\identityiq.jar`$time"
$env:CLASSPATH="$env:CLASSPATH;$env:IIQPATH\WEB-INF\lib\sqljdbc4.jar"
$env:CLASSPATH="$env:CLASSPATH;./split"

$commandline="java sailpoint.launch.Launcher console iiqBeans -u $iiquser -p $iiqpass -c "+[char]34+"export -clean $env:exportpath\Application.xml Application"+[char]34

$commandline

cmd /c $commandline

任何提示？

======================= 快速更新......

我在cmd windows提示符中手动设置变量并进入PS Cmd提示符。

当我运行没有参数的java命令时，我得到了以下内容

C:\>java sailpoint.launch.Launcher
Usage: sailpoint.launch.Launcher [ -d ] [<application> | <class>] <arguments>...

Applications:
  setup           Bootstrap configuration utility
  schema          Schema file generator
  upgrade         Perform data upgrades between releases
  patch           Perform data upgrades post release
  console         Administrative console
  encrypt         Administrative console
  integration     Integration console
  oim             OIM Integration console
  exportschema    Data Export console
  exportviews     View Export console
  keystore        Key Store console
  parse           XML file parser

但是当我尝试在PS命令行中运行时，我得到了以下内容：

PS C:\> java sailpoint.launch.Launcher
Exception in thread "main" java.lang.NoClassDefFoundError: sailpoint/launch/Launcher
Caused by: java.lang.ClassNotFoundException: sailpoint.launch.Launcher

Could not find the main class: sailpoint.launch.Launcher.  Program will exit.

Answer 1

应该使用的命令是

java -cp .\identityiq.jar sailpoint.launch.Launcher

-cp选项负责在Powershell命令行中设置CLASSPATH。

从Powershell脚本调用Java函数时的java.lang.NoClassDefFoundError
