How to build OpenGrok from source
The easiest way to build (or modify) {OpenGrok is by using any modern IDE, but you can also build {OpenGrok from the command line.
You need the following:
- JDK 11 or higher
- The source code is located in a git repository
- First build has to happen with mvn which downloads all dependencies
The first thing you need to do is to check out the source code. You can check out the source with the following command:
git clone https://github.com/oracle/OpenGrok
(or clone any of your forks)
OpenGrok does have a maven pom.xml for its modules.
First build should download all needed dependencies, so don't get scared about missing jars.
If you use NetBeans you should be able to open OpenGrok as a project and build it from there. Specifically, open pom.xml from the root directory, and click Run => Build Project (opengrok). (Ignore "Resolve problem" for jar files other than junit, but setup a webapp server for the -web-nbproject application.)
If you want to build from the command line, execute the following command (it will need internet connection first time, so setup any proxies if needed):
./mvnw compile
or (to clean and start from scratch)
./mvnw clean compile
