Download and install following:

• Java SE Development Kit 8 (http(see README for version requirements; https://wwwfoojay.oracle.comio/technetwork/java/javase/downloads/jdk8-downloads-2133151.htmldownload/ can help to find a JDK)
• IDE - NetBeans  recommended recommended (note: if you install NetBeans you are ready to go since you'll also get bundled Ant and GIT, so no further installation and configuration will be required, so you can continue from Getting Started section)
• Apache Ant (https://ant.apache.org/)
• GIT (https://git-scm.com/downloads)
  

Following instructions  assume assume that you already have an account on on https://github.com and you are familiar with basic GIT operations as fork (making copy of project under your account) and clone (making your local development copy)

...

If you plan to submit changes, then you should fork the Apache NetBeans GitHub repo, to do this please follow the steps here on GitHub - just replace the example repository for https://github.com/apache/incubator-netbeans.  If you don't plan to submit changes and want to just browse the codebase beforehand, you can always clone the main GitHub repository, but you won't be able to submit pull requests from this.

In the examples below, if you have created a fork then please clone your fork and not the apache repository.

Step	Without NetBeans	With NetBeans
Clone	Clone the Apache NetBeans Git Repo (https://github.com/apache/ incubator- netbeans) Code Block language bash $ git clone git@github.com:apache/ incubator- netbeans.git $ cd incubator- netbeans Info If you are cloning your own fork, then the clone command would be different, please have a look at your fork in GitHub.

Build	Code Block language bash $ ant
Run	Code Block language bash $ ant tryme
Debug	You can pass java options through the netbeans launcher via -J<javaarg>. This will run netbeans with debugging enabled: Code Block language bash title Start pre-built NetBeans and wait for debugger to attach $ /bin/netbeans -J-agentlib:jdwp=transport=dt_socket,suspend=y,server=y,address=9009 To run a freshly build netbeans you can invoke: Code Block language bash title Run development version through Ant waiting for debugger $ ant -Ddebug.port=9009 tryme This will start the build IDE with a test userdir and it will wait on tcp port 9009 for debugger connections.
