Subject Re: Generating Incorrect fat jar using maven-assembly-plugin in maven 2 with war packaging
Date Wed, 16 Apr 2014 05:27:06 GMT
Hi,
Which version of the war plugin are you using?

BTW, you say it's OK with maven 3. Can't you just upgrade? Maven 2 is many
years old and has already been officially end of lifed (
http://maven.apache.org/maven-2.x-eol.html).

And about what you're doing: I'm unsure about why you seem to unnecessarily
try to package a fat jar although your target is a war?

Cheers
