I looked at the maven docs , however I can't understand this statement: "This plugin provides the capability to package the artifact in an uber-jar, including its dependencies and to shade - i.e. rename - the packages of some of the dependencies." The documentation on the page doesn't seem very newbie-friendly. What is an "uber jar?" Why would

And what is the correct way, if any, to do this in 1 hop? 回答1: First off, note that when you say this: BAR=$(basename $FOO) # result is BAR="baz" BAZ=${BAR:0:1} # result is BAZ="b" the first bit in the construct for BAZ is BAR and not the

Specifically, how do I get pluses ( + ) correctly escaped because Spring is interpreting as spaces , so, I need to encode them. I tried using UriComponentsBuilder like this: String foo = "fo+o"; String bar = "ba r"; UriComponentsBuilder ucb =
