NetBeans 8.1 Activation Failure

Question

I am trying to install NetBeans 8.1 on my Ubuntu 14.04.3 LTS. When I try to create a new project, it shows an error, saying that "not all requested modules can be enabled". I tried activating it from the plugins, but to no avail.

Why is this happening, and what can I do to resolve it?

@WillShackleford As the installation path is `/home/khlim/netbeans-8.1` I would assume it was not installed from a Ubuntu repository. — SubOptimal, Nov 23 '15 at 13:15
Maybe you tried to run Netbeans with an JRE not a JDK (see https://forums.netbeans.org/post-167346.html) — SubOptimal, Nov 23 '15 at 13:20

I had the same problem with NetBeans 8.1 on Linux Mint 17.2 and I found the solution (during install a have chosen wrong JDK directory).

If a compatible JDK installation cannot be found, you might need to manually add a path to the JDK installation directory by doing the following:

Open the netbeans.conf file located in the netbeans/etc directory in a text editor.
Enter the location of a compatible JDK installation for the netbeans_jdkhome option. The default location in Windows is C:\Program Files\Java\jdk1.7.0_67 or similar.
In my case: /usr/lib/jvm/java-8-oracle/
Save the netbeans.conf file and run the executable file in the netbeans/bin directory.

Yes, this fixed the problem on Ubuntu for me too. – Alexandros May 24 '16 at 09:15
Works on Ubuntu 14.04. – magic_al Nov 22 '16 at 08:37
Worked for me on Ubuntu 16 – Emiliano Sangoi May 17 '17 at 19:36
If someone experiences this issue with openSUSE, the location that should be used for `netbeans_jdkhome` is usually `/usr/lib64/jvm/java-1.8.0-openjdk-1.8.0`, but bear in mind that this is true for **java-1_8_0-openjdk**. For java-1_7_0-openjdk and java-9-openjdk you would need to tweak the path accordingly. – iganev May 29 '17 at 21:45

Just in case, I solved this just by commenting out the following line;

netbeans_jdkhome="/usr"

To

#netbeans_jdkhome="/usr"

Edit:

The directory of the above code is inside the file ~/netbeans-8.1/etc/netbeans

After installing JDK 8, your solution resolved my issue. – zkjellberg Sep 26 '16 at 01:13

To clarify, this line was located in ~/netbeans-8.1/etc/netbeans.conf for my installation. – zkjellberg Sep 26 '16 at 01:21

For Netbeans 8.2 and actual Debian or Ubuntu i had to be more precise and declase netbeans_jdkhome=" /usr/lib/jvm/java-8-oracle" . This worked for me – wegus Oct 11 '16 at 12:38
As mentioned by @zkjellberg . The line was located in ~/netbeans-8.1/etc/netbeans.conf. I forgot to put it together – Wei Oct 21 '16 at 02:07
fixing JAVA_HOME should fix this as well – cody.tv.weber May 09 '19 at 16:17

Make sure that right JDK directory chosen in the installation wizard if you not sure you can change it from C:\Program Files\NetBeans {netbeans version}\etc you will see a file which is netbeans.conf edit it(I am using Notepad++ for that) At the bottom of the file, you will see a line netbeans_jdkhome="C:\Program Files\Java\{jdk directory you want}" make sure it is valid JDK and it is JDK, not JRE
