jar file too big - corrupted jar file

Question

rladstaetter opened this issue 5 years ago · 3 comments

i had a problem when packaging a jar file into an exe, which grew too big due to transitive dependencies.

the jar file itself starts via 'java -jar xyz.jar' fine, but when i wrap it using this plugin i get an:

'Error: Invalid or corrupt jar file'

error message. Jar file size at about 113 MB, another version of this jar file with 112,9 MB works.

This plugin just wraps Launch4j and doesn't do any magic with jars, except that you can use Maven Assembly Plugin to create your own fat jar.

thank you for your fast response.

in fact, if i circumvent wrapping the jar it runs perfectly fine. (using parameter 'dontWrapJar').

the bad thing about this is that then i have my exe AND my jar file.

I'll close this issue, since I assume its more a problem of launch4j then.
