The following quick and dirty bash script will take a pom and a jar and fake a maven build based on the source files for that that can be found in the current directory.
Really useful when running mvn dependency:analyze on a project you are validating POMs for.
#!/bin/bash
if [ "A$3" == "A" ]
then
echo "Syntax: $0 pomfile jarfile dir"
return
fi
rm -rvf "$3/src"
mkdir -p "$3/src/main/java"
cp -f "$1" "$3/pom.xml"
for name in $(jar -tf "$2" | sed -n -e "/\\$/d;s/\\.class/.java/p")
do
echo -n "Looking for $name ... "
loc="$(find . | fgrep $name | head -n 1)"
if [ "A$loc" == "A" ]
then
echo "NOT FOUND"
else
echo "$loc"
mkdir -p "$3/src/main/java/$(dirname $name)"
cp "$loc" "$3/src/main/java/$name"
fi
done
