What is the exact issue?

dapper brook
#

I have installed proguard and there is no .jar

hoary salmon
#

How did you configure Prouard?

#

Did you configure a main class?

#

Can you run the JAR before proguard?

dapper brook
#

yes

#

my problem is proguard.jar not existing

hoary salmon
#

Can you rename it to proguard.zip?

#

and then show its content?

#

also run the dir command in the cmd window first

dapper brook
#

it didn't come with proguard when I downloaded it

hoary salmon
#

Oh so the issue is you cannot run proguard?

dapper brook
hoary salmon
#

What is in there?

#

I thought you had an issue running the minified executable

dapper brook
#

heres the bin folder

hoary salmon
#

What happens when running proguard.bat from cmd?

#

Did your antivirus maybe delete the JAR?

dapper brook
hoary salmon
#

I meant you run proguard.bat from inside cmd

dapper brook
#

ok

dapper brook
hoary salmon
#

Can you show the content of the proguard.bat file?

dapper brook
hoary salmon
# dapper brook

Can you show the full command you were executing to get that and the full output?

dapper brook
#

i just went into cmd and ran the command "proguard.bat"

hoary salmon
#

Can you right-click on the proguard.bat file and select edit?

#

What other files and directories are in the proguard installation other than bin?

dapper brook
# hoary salmon Can you right-click on the proguard.bat file and select edit?

REM Note: when passing file names containing spaces to this script,

:home

java -jar "%PROGUARD_HOME%\lib\proguard.jar" %*

#

Can you run proguardgui.bat?

dapper brook
#

yes

hoary salmon
#

ok that should work

#

in input/output, you should be enable to configure the JAR etc

#

and then use other options

#

and in shrinking you can do other things

dapper brook
#

heres some errors i got

hoary salmon
#

these are warnings from what I see

#

What happens when running the generated JAR?

dapper brook
#

cat

#

*cant

hoary salmon
#

oh ok

#

Cab you show your configuration?

dapper brook
hoary salmon
#

Was that file created by the GUI?

dapper brook
#

theres a save configuration button

hoary salmon
#

Can you show the options in the GUI?

dapper brook
hoary salmon
#

e.g. for input/output and shrinking

dapper brook
hoary salmon
#

Can you add -dontwarn javax.swing.**?

#

idk where exactly to add it

hoary salmon
# dapper brook

otherwise what happens if you disable the Swing L&F button there?

dapper brook
#

same thing

hoary salmon
#

What's the output with the dontwarn thing

dapper brook
#

idk where to add it

hoary salmon
#

maybe put it in a file

#

add the dontwarns (you'd also need -dontwarn java.awt.**)
and then run proguard.bat @yourconfigfilehere

#

something like that maybe

dapper brook
#

Are there any other ways to shrink a jar file?

#

i vaguely remember reading something about 7zip
