context: rather than downloading IDE's and SDK's manually, where possible, I prefer to use automation such as: rVM, SDKman, snap, and umake or ubuntu make. The scope of this question is limited to tools like this, such as apt and not to manual downloads.

How do I install Netbeans 9 using umake?

I installed umake with apt because snap has problems with umake.

Java 11 was installed with SDKman, although I also installed 8.0.192-zulu and 9.0.7-zulu as well.

Ubuntu make only installs Netbeans 8.2.

How do I get umake to download Netbeans 9?

Ubuntu Make

Ubuntu Make is a command line tool which allows you to download the latest version of popular developer tools on your installation, installing it alongside all of the required dependencies (which will only ask for root access if you don't have all the required dependencies installed already), enable multi-arch on your system if you are on a 64 bit machine, integrate it with the Unity launcher. Basically, one command to get your system ready to develop with!

Since I'm at version 8.2 for Netbeans, presumably there's a better way to utilize umake.

Maybe I should downgrade Java:

https://askubuntu.com/a/1093681/45156

and then re-install NB. I don't see how that would update netbeans, however.

footnote: actually, Netbeans 8.2 installs fine from the snap version of ubuntu-make or umake.

    Possible duplicate of NetBeans doesn't work – karel Dec 15 '18 at 18:24
  • Not really a duplicate because it's confined to using ubuntu make. I'll update at a later point. My two cents, at least. – Thufir Dec 16 '18 at 0:10
  • What is the XY problem? "The XY problem is asking about your attempted solution rather than your actual problem." – karel Dec 16 '18 at 4:53
  • @karel I believe this isn't a duplicate since it not only focuses on "Netbeans doesn't work' but the reason why umake can't install v9.0 – Kulfy Dec 16 '18 at 8:16

According to Ubuntu-make's official repository on GitHub last time Netbeans data such as link was updated/committed on 30 March 2017 while Netbeans 9.0 was released on 29 July 2018. So, I believe as of now it is impossible to install Netbeans 9.0 via ubuntu-make until it updates the details. You'll find that all folders here which contain details about Netbeans have details of version 8.2.

Also, according to Netbeans 8.2 official release notes:

The tested JDK for this release is JDK 8u101 for Windows, Linux, and OS X. The 8.2 version of the IDE cannot be installed or run on the JDK older than JDK 8.

So, I think its better to downgrade the Java and use Netbeans 8.2 or install Netbeans 9.0 using other methods.

  • it installed and runs, but is 8.x, not 9. Odd that ubuntu make doesn't update netbeans. grrr. thanks for the deep dive into GitHub. I had no idea how to get more info on that. Thanks, also, for confirming incompatibility between JDK and NB versions. – Thufir Dec 16 '18 at 0:05

    @Thufir You can make a request to update Netbeans on GitHub. – Kulfy Dec 16 '18 at 7:32
