Apache NetBeans

Apache NetBeans is an open source development environment, tooling platform, and application framework.

Build status

• GitHub actions
  • 
  • 
• TravisCI:
  • 
• Apache Jenkins:
  • Linux:
  • Windows:
• License Status ( Apache Rat and ant verify-libs-and-licenses )
  • 

Requirements

• Git
• Ant 1.9.9 or above
• JDK 11 or above (to build and run NetBeans)

Notes:

• NetBeans license violation checks are managed via the rat-exclusions.txt file.
• Set JAVA_HOME and ANT_HOME appropriately or leave them undefined.

Building NetBeans

Build with the default config (See the cluster.config property.)

$ ant

Build the basic project (mainly, JavaSE features):

$ ant -Dcluster.config=basic

Build the full project (including Groovy, PHP, JavaEE/JakartaEE, and JavaScript features):

$ ant -Dcluster.config=full

Build the NetBeans Platform:

$ ant -Dcluster.config=platform

Notes:

• You can also use php, enterprise, etc. See the cluster.properties file.

Generating Javadoc

Build javadoc:

$ ant build javadoc

Note Run javadoc-nb task in Netbeans to run the javadoc build and display it in a web browser.

Running NetBeans

Run the build:

$ ant tryme

Note: Look in nbbuild/netbeans for the NetBeans installation created by the build process.

Reporting Bugs

Bugs should be reported to https://github.com/apache/netbeans/issues

Log, Config and Cache Locations

• start config (JVM settings, default JDK, userdir, cachedir location and more):
  netbeans/etc/netbeans.conf
• user settings storage (preferences, installed plugins, logs):
  system dependent, see Help -> About for concrete location
• cache files (maven index, search index etc):
  system dependent, see Help -> About for concrete location
• default log location (tip: can be inspected via View -> IDE Log):
  $DEFAULT_USERDIR_ROOT/var/log/messages.log

Note: removing/changing the user settings directory will reset NetBeans to first launch defaults

Full History

The origins of the code in this repository are older than its Apache existence. As such significant part of the history (before the code was donated to Apache) is kept in an independent repository. To fully understand the code you may want to merge the modern and ancient versions together:

$ git clone https://github.com/apache/netbeans.git
$ cd netbeans
$ git log platform/uihandler/arch.xml

This gives you just few log entries including the initial checkin and change of the file headers to Apache. But then the magic comes:

$ git remote add emilian https://github.com/emilianbold/netbeans-releases.git
$ git fetch emilian # this takes a while, the history is huge!
$ git replace 6daa72c98 32042637 # the 1st donation
$ git replace 6035076ee 32042637 # the 2nd donation

When you search the log, or use the blame tool, the full history is available:

$ git log platform/uihandler/arch.xml
$ git blame platform/uihandler/arch.xml

Many thanks to Emilian Bold who converted the ancient history to his Git repository and made the magic possible!
