Ant构建NSIS失败

Question

I'm trying to make the installer exe of a java project using it's build.xml from eclipse but the build fails.

[zip] Building zip: D:\Documents and Settings\Administrator\My Documents\Workspace\JDownloader\dist\JDownloader_windows_13312.zip
[echo] Clean Windows Setup...
[nsis] java.io.IOException: Cannot run program "makensis": CreateProcess error=2, The system cannot find the file specified

This appears to be the section of build.xml that is failing:

<echo message="Clean Windows Setup..." />
  <nsis script="${exe.windows.script}" verbosity="2" />
  <echo message="Kikin Windows Setup..." / 

Answer 1

The message

CreateProcess error=2, The system cannot find the file specified

arises because Ant is unable to locate the script you are trying to run.

The script name (makensis? .nsi?) and location appear to be set in the Ant property exe.windows.script . Suggest you check that is set, set as you expect, and that the script exists and is executable at that location.

edit: this is similar to an entry in the Ant FAQ :

A common problem is not having the executable on the PATH. In case you get an error message Cannot run program "...":CreateProcess error=2. The system cannot find the path specified. have a look at your PATH variable.

Just type the command directly on the command line and if Windows finds it, Ant should do it too. (Otherwise ask on the user mailinglist for help.) If Windows can not execute the program add the directory of the programm to the PATH (set PATH=%PATH%;dirOfProgram) or specify the absolute path in the executable attribute in your buildfile.
