In short: Get the source code. Install Apache Ant In the parent directory execute the ant target "ant". That'll give you a list of "targets", the interesting ones at this point are "idea", "netbeans" or "eclipse". Those will create a project you can open in the respective IDEs. NOTE: the first time you run an ant target, you may be prompted to run a specific target to install "ivy". For Solr, go into the solr directory and execute "ant server" and/or "ant dist" to build Solr. At that point you have just what you'd get from downloading and exploding the standard distro. Of course you have to have java installed. Java 8 is the usual standard at this point. Again, the solr "How to Contribute" page walks you through the steps in more detail, I don't know why it's not found at present but it should come back sometime Best, Erick On Tue, Jan 8, 2019 at 9:36 AM Rajdeep Sahoo <rajdeepsahoo2...@gmail.com> wrote: > > How can I set up code Base and do the changes.
