Jar 到 exe 使用 NSIS

Question

所以我正在寻找一个程序（这是免费的），它可以让我从 jar 到 exe 并包装 JRE...直到现在我使用 Launch4J 并且我也尝试了其他人，但我发现 NSIS 更强大，我think 会适合我正在寻找的东西，但是我在定义 CLASSPATH 和 CLASS 时遇到了问题。

这是代码：

Name "Tool"
Caption "Internal"
Icon "UIT.ico"
OutFile "Tool.exe"

VIAddVersionKey "ProductName" "Tool"
VIAddVersionKey "Comments" "Internal"
VIAddVersionKey "CompanyName" ""
VIAddVersionKey "LegalTrademarks" ""
VIAddVersionKey "LegalCopyright" ""
VIAddVersionKey "FileDescription" "Tool"
VIAddVersionKey "FileVersion" "3.0.1934"
VIProductVersion 3.0.1934"

!define CLASSPATH "ApplicationTool.jar"
!define CLASS "v3build1934"
!define PRODUCT_NAME "Tool"

; Definitions for Java 8.0
!define JRE_VERSION "8.0"
!define JRE_URL "http://javadl.sun.com/webapps/download/AutoDL?BundleId=24936&/jre-6u10-windows-i586-p.exe"
;!define JRE_VERSION "8.0"
;!define JRE_URL "http://javadl.sun.com/webapps/download/AutoDL?BundleId=22933&/jre-1_5_0_16-windows-i586-p.exe"

; use javaw.exe to avoid dosbox.
; use java.exe to keep stdout/stderr
!define JAVAEXE "javaw.exe"

    StrCmp 0 $0 0 UAC_Err ; Error?
    StrCmp 1 $1 0 UAC_Success ;Are we the real deal or just the wrapper?
    Quit

  UAC_ElevationAborted:
    # elevation was aborted, run as normal?
    MessageBox MB_ICONSTOP "This installer requires admin access, aborting!"
    Abort

  UAC_Err:
    MessageBox MB_ICONSTOP "Unable to elevate, error $0"
    Abort

  UAC_Success:
    StrCmp 1 $3 +4 ;Admin?
    StrCmp 3 $1 0 UAC_ElevationAborted ;Try again?
    MessageBox MB_ICONSTOP "This installer requires admin access, try again"
    goto UAC_Elevate 
FunctionEnd

我需要在这两个中放入什么，还是应该将脚本移到其他地方，例如 netbeans 项目所在的位置？？？

您可以通过调用SetEnvironmentVariable为 NSIS 进程和子进程设置环境变量：

System::Call 'Kernel32::SetEnvironmentVariable(t "CLASSPATH", t "c:\some\path\you\got\from\the\registry")'
