Prof. [~aloraine] as per the following lines, I think we are attempting to exclude all the folders namely, core, distribution, doc, etc.
<entry location="core" fileType="regular" />
<entry location="distribution" fileType="regular" />
<entry location="docs" fileType="regular" />
<entry location="main" fileType="regular" />
<entry location="plugins" fileType="regular" />
But the contents of the doc folder are still visible in the installation directory. I am sorry for not noticing this earlier. Just wanted to confirm is it okay if that folder is visible?
Suggestions for testing:
.git directory
.gitignore directory
pom.xml
scripts for running IGB from command line (except Linux installer maybe?)
