can't install STS 3.8.4 on Ubuntu 12.04

jazzo · 04-06-2017, 01:45 PM

I run into an interesting problem. I have a machine with Ubuntu 12.04 STS and I wanted to install STS 3.8.4. I have the jdk 8 installed but when I try to run STS I get this message "Version 1.6.0_41 of the JVM is not suitable for this product. Version: 1.8 or greater is required." SO, I've had a look on SO and a few forums, I discovered this command sudo update-alternatives --config java but I only get these results:

Code:

linux-Dell-System-XPS-L702X:~/opt$ sudo update-alternatives --config java
There are 2 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                            Priority   Status
------------------------------------------------------------
  0            /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java   1061      auto mode
* 1            /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java   1061      manual mode
  2            /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java   1051      manual mode

Press enter to keep the current choice[*], or type selection number: 2

still no jdk 8, which, as I said, is installed on my machine because I use it with eclipse. Now, is there a way to manually set it in some kind of STS configuration file as far as you know or any other way that I seem to fail to identify?

You will have to make a java8 entry to /etc/alternatives/ , like this example

Code:

sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/1.8.0_121-b13/bin/java 4

Please replace with actual path, and actual version.

When done, you can run the config command again :
sudo update-alternatives --config java

ah OK, I see, thanks. This is what I got as output:

Is that OK that my jdk sits inside the home directory?

Code:

Now if I try to run STS I get another error:
A Java Runtime Environment (JRE) or Java Development Kit (JDK)
must be available in order to run STS. No Java virtual machine
was found after searching the following locations:
/home/antobbo/Documents/sts-bundle/sts-3.8.4.RELEASE/jre/bin/java
java in your current PATH

Do I have to set the java version even inside the PATH variable? I thought that was a windows thing...and I've definitely downloaded STS for linux

Suggest : Install the latest java8 (runtime) to /usr/lib/jvm/.

Download jre-8u121-linux-x64.tar.gz ( If Ubuntu 12.04 - amd64 ) from
http://www.oracle.com/technetwork/ja...s-2133155.html

Code:

cd /usr/lib/jvm/
sudo tar xvf /home/antobbo/Downloads/jre-8u121-linux-x64.tar.gz

sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jre1.8.0_121/bin/java 5

After sudo update-alternatives --config java :
java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)
