OpenGrok is a fast and usable source code search and cross reference engine, written in Java. It helps you search, cross-reference and navigate your source tree. It can understand various program file formats and version control histories of many source code management systems.

Official page of the project is on: https://oracle.github.io/opengrok/

See https://github.com/oracle/opengrok/wiki/How-to-setup-OpenGrok

OpenGrok uses semantic versioning and the version components further indicate more details about updating to newer version. The version scheme is major.minor.micro and change in any component is interpreted as:

• major - major backwards incompatible update, will require full reindex as well as configuration changes
• minor - full clean reindex of your repositories is needed (e. g. index format has changed)
• micro - redeploy web application

Generally it is possible to go backward only within the micro version.
