Jar2Exe Command Line

Command Line mode is supported


Jar2Exe Command Mode is a powerful and direct way to use Jar2Exe.

Every feature of Jar2Exe is supported at command line mode.

 At the last step of  Jar2Exe Wizard mode, you can get a equivalent command line string, so usually you need not to write the whole long command line by yourself.

Keep files not hidden


I'm having some problems when trying to generate an encrypted or hidden exe via CLI:

I need to keep META-INF folder not hidden, in GUI I can select that option, isn't it in command line?

remove artificial sleep

When I run j2ewiz from command line, it waits around 10 seconds before exit, which is very annoying when integrated with my installer script. Most probably the sleep is there to allow time for the users to run it, but some users might just run it integrated into other tools.

More exactly it displays the following text for ~10 seconds:
Executive file "C:\Myprojects\pacman\pacman.bin" created successfully.

Can you add a /nowait command line option which will eliminate this extra wait time at the end?

(j2ewiz might just exit with 0 on success or 1 with error, so it could be easily integrated in install scripts)

Thank you.




There is no artificial sleep

The wait is because Jar2Exe is processing the converting. You can try a small jar it will end immediately.

Yes j2ewiz will return 0 on success, non-0 on fail and different result means different fail reason.

remove artificial sleep

But it already displays "X.bin created successfully".

How it could display "create successfully" if still processing the converting?

I am not talking here about the overal time required to run j2ewiz.exe. Only the time while it displays "X.bin created successfully".

silent exe generation using .j2e project file


is it possible to automate the generaion of the output exe using the input .j2e project file?

Would be really great to have such a feature!

Use '/make'

Thank you for your advice. Please use:

j2ewiz /make xxx.j2e

instead of the long command line.
