On this article we will discuss how to install Apache NetBeans version 12.1 on Linux CentOS 8 Desktop.


Apache NetBeans is an integrated development environment (IDE) for creating any applications from its modular components called as modules. Netbeans supports any programming language, such as : Java, PHP, HTML, JavaScript, C, C++, Ajax, JSP, Ruby on Rails and other programming languages using extensions. NetBeans runs on Windows, macOS, Linux and Solaris. On this article, we will discuss how to install Apache Netbeans version 12.1 on CentOS 8 Desktop.

Before continuing read the article, it is better to know the NetBeans history as mention in NetBeans framework began in 1996, as Java IDE student project under the guidance of the Faculty of Mathematics and Physics at Charles University in Prague. Then NetBeans was acquired by Sun Micrsosytem in 1999, and then Oracle acquired Sun Microsystem in 2010. Oracle submitted a proposal to donate the NetBeans project to the Apache Software Foundation in 2016.

Apache NetBeans Installation

Apache NetBeans 12 is latest LTS version of the IDE, which was released on June 4, 2020. On this article, we will install Apache NetBeans version 12.1. The installation process will consist of several steps, namely:

  1. Install Java JDK
  2. Download NetBeans 12 IDE
  3. Install NetBeans 12 IDE

Install Java JDK

Apache Netbeans needs Java JDK to run on the system, so the first step on installing Netbean is to check if the system (CentOS 8) has had Java JDK installed, if it was No, then we instal Install Java JDK with teh following step.

[ramans@localhsost ~]$ java -version
openjdk version "1.8.0_252"
OpenJDK Runtime Environment (build 1.8.0_252-b09)
OpenJDK 64-Bit Server VM (build 25.252-b09, mixed mode)

On our system, it was already OpenJDK version 1.8.0, I think it is better if we have the latest OpenJDK on our system, then we will install the latest OpenJDK version and make it as default.

[ramans@localhsost ~]$ sudo dnf install java-11-openjdk-devel

The output will be :

java-11-openjdk-1: java-11-openjdk-devel-1:

To switch from the OpenJDK existing to the new one, then submit the command line :

[ramans@localhsost ~]$ sudo alternatives --config java
There are 2 programs which provide 'java'.
Selection Command
*+ 1 java-1.8.0-openjdk.x86_64 (/usr/lib/jvm/java-1.8.0-openjdk-
2 java-11-openjdk.x86_64 (/usr/lib/jvm/java-11-openjdk-
Enter to keep the current selection[+], or type selection number: 2
OpenJDK switch version
OpenJDK version 11.0.9

On this step, we have OpenJDK version 11.0.9 on our system, the we will continue to the next step for installing Apache Netbean 12 LTS.
