Install Netbeans IDE

First, you should install Java. As a general thumb of rule, the JDK 1.8 version is the most used and the most stable JDK you could use. Read more at quora about this.

Step 1 – Install Java

Install the Java version you need

Step 2 – Download and extract latest Netbeans

Download latest netbeans from the official site. Create a directory named opt in your home directory and extract the archive you downloaded to that directory

Step 3 – Setup the JDK path

Unfortunately you have to manually configure the directory of the JDK that Netbeans will use. To find the path of the installed JDKs you can type:

$ update-java-alternatives -l

A sample output would be:

java-7-oracle 1078 /usr/lib/jvm/java-7-oracle
java-8-oracle 1081 /usr/lib/jvm/java-8-oracle

What you have to do is to locate the file netbeans.conf and set the netbeans_jdkhome variable to one of the paths displayed above.

The easiest way to find netbeans.conf is to run the following command:

find / -name netbeans.conf 2> /dev/null
locate netbeans.conf

This may take a while.

You could also look at the following standard directories:

  • /home/netbeans-X.Y/etc/netbeans.conf
  • /usr/local/netbeans-X.Y/etc/netbeans.conf

After you have found netbeans.conf, you perform the following steps:

  1. open netbeans.conf with any text editor you like
  2. set netbeans_jdkhome variable to point to the proper location, eg:
