Netbeans 8.1 won't make it past "Turning on modules" screen

Question

This week I installed netbeans 8.1 in my fresh ubuntu 18.04 installation.Prior to that I have installed jdk,jre and configured the JAVA_HOME variable.After trying to open netbeans I get the netbeans loading screen.However when the loading screen writes "Turning on modules" after a while netbeans will close.I've tried starting it through terminal but I get no errors.However I found this text files in my netbeans var folder

Any ideas why this is happening?

Solution

I suggest all of you read the chat that is posted on comments.I couldn't fix netbeans 8.1.What I did though was to download the latest version (8.2) from the site and install it using the bash script.However after opening netbeans 8.2 I couldn't create a new project.

Then I found the folowing stack overflow question: https://stackoverflow.com/questions/46476470/cant-create-project-on-netbeans-8-2

In summary what I have to do was to find my netbeans.conf file and change my java_home path

Netbeans 8.1 doesn't work in Ubuntu 18.04 by Netbeans 8.2 can be installed by ubuntu-make with umake ide netbeans and it works in 18.04, but I don't think it's worth installing in Ubuntu 18.04 because the Eclipse snap package (eclipse Extensible Tool Platform and Java IDE) is a much better IDE for Java than Netbeans in 18.04.

I'am a student and my professor want us to use netbeans :(

[karel]

Your professor and you will be happy to know that Netbeans 8.2 works in 18.04.

[Manos Kounelakis]

I will try it and will let you know

[Manos Kounelakis]

but why isn't it working on 18.04?

[karel]

Netbeans 8.2 doesn't have any problem recognizing openjdk-11-jdk automatically in 18.04. Netbeans 8.1 does not recognize openjdk-11-jdk automatically in 18.04, and it does not recognize openjdk-8-jdk either, even when openjdk-8-jdk is selected as the default java.

[Manos Kounelakis]

I don't have jdk 11

[karel]

openjdk-11-jdk isn't Java 11, it's just a funny package name in 18.04. I uninstalled it and tried opening Netbeans 8.1 with only openjdk-8-jdk installed and it didn't recognize openjdk-8-jdk either.

[Manos Kounelakis]

I tried umake ide netbeans but it throws segmentation fault

Let us continue this discussion in chat.

@karel Can you post your upvoted comment as an answer so I can use this one as the dupe of this one? Please? Pretty Please???

[Fabby]

@karel Yeah, read chat transcript; but OP has logged on 10 hours ago but didn't post an answer, so... :-)

[Manos Kounelakis]

@Fabby sorry for being late :)

[Fabby]

No worries: answer posted so upvoted! ;-)

[Manos Kounelakis]

The post is about 8.1 not 8.2
