I have a file called versionInfo.txt. This file among other things has the following text: \"Implementation-Version: 7.5.0.1\".
I need to retrieve the version value
For the second part of your question, retrieve the version info.. : If you need to read the Implementation-Version from the Manifest of a jar you may use a macrodef, f.e. :
$${foobar} => ${foobar}
