Java Platform Module System Support

Java Application project extensions

NetBeans 9 supports JPMS (Jigsaw) to full extent. Modulepath was added as a crucial paradigm to NetBeans in addition to Classpath.


The picture below shows the structure of JavaSE projects with JUnit tests in same module and with own module:

Java Modular Application Project type

New project called Java Modular project was added. This allows to develop several JDK9 modules in one NetBeans project (Ant based). Advantage of this project over several Java SE project each containing 1 module is that dependencies are simply managed by declaring appropriate exports and requires in files and all modules in the project are being compiled at once.


Following picture depicts how Java Modular Project can look like.

Other Java 9 features

Every JavaSE (with or Java Modular App project can be packaged into JLink image allowing seamless distribution of app and required modules.


HTML5 tags are supported in NetBeans editor and HTML5 JavaDoc can be generated using projects Properties | Documenting customizer.

Maven projects and JDK 9 modules


Java Shell is a tool in JDK9 defined in JEP 222 to introduce REPL (read-eval-print-loop) capabilities to Java. NetBeans provides integrated console-like UI for the Java Shell, leveraing NetBeans editor capabilites. NetBeans can support the tool with the user project configuration, so the Java Shell is set up to work with project classes and libraries.


Snippets written in JShell can be redefined and tested, even against a running code. When prototype is ready, it can be saved to a regular java source file and integrated with the project.



All the PHP support for NetBeans 9 was contributed by our NetBeans user Junichi Yamamoto.

PHP 7.1 Support


  • Class constant visibility


  • PHP version in Project Properties dialog

PHP 7.0 Support


  • Context sensitive lexer



  • Hint for void return types


  • Lowercase code completion for TRUE, FALSE, and NULL constants. Enabled by default.


  • Code folding for arrays



  • Autocompletion for delimiters, brackets, and quotes

Java Profiler

Profiler Results Improvements

Actions to expand and collapse nodes have been added to the profiler treetable results. For example, the Expand Topmost Path action makes it very easy to select the performance bottleneck in the EDT. For Methods results the Show Only This Thread and Hide This Thread actions have been added.

Resizable Popups

The popups used to configure the profiler or filter the results can now be resized, which makes it easier to handle long class or method names.


Dbx support

C/C++ debugger supports dbx native debugger.

Clang-format support

C/C++ editor supports popular formatting tool clang-format.

Clank-based Diagnostics (Experimental)

We have added new diagnostics based on the Clank (java clang) that can show you error path for the problem discovered, use Fix it suggestions.
