problem running eclipse on ubuntu?

Question

I downloaded eclipse on ubuntu. But when I run it it show following error.

A Java Runtime Environment (JRE) or Java Development Kit (JDK)
must be available i         


        

Answer 1

If you allready installed java** you need to add the Java-Path to your eclipse.ini

in my case it's located at:

/usr/lib/eclipse/eclipse.ini

there you need to add direct under the "openFile" statement, where you replace the path with your java path:

-vm
/usr/lib/jvm/java-7-openjdk/bin/java    //!replace with your path to java!

** check wether java is installed by typing the commands

java -version 

or

javac -version

If you are sure that java is installed, but it's not found you may have multiple versions installed, check that by:

sudo update-alternatives --config java

and select installation first

Answer 2

You need to install either the openjdk-7-jre or oracle-java7-jre package.

sudo apt-get install openjdk-7-jre

Note that openjdk-7-jre is easier to install, because it's available via the standard Ubuntu repository, whereas you have to build oracle-java7-jre yourself using java-package.

Answer 3

I had similar problem. It solved after, I have download JRE from http://www.oracle.com/technetwork/java/javase/downloads/jre7-downloads-1880261.html

and put it in the path of eclipse as shown below -

abc@ubuntu:~/Downloads/eclipse$ ls

about_files
configuration
eclipse.ini
icon.xpm
p2 about.html
dropins
epl-v10.html
jre
plugins artifacts.xml
eclipse
features
notice.html
readme

I hope it helps.

Answer 4

Just copy jre and paste in eclipse folder that's it. After this just click on eclipse icon to launch eclipse. Thanks.

Answer 5

You need to install the JDK or OpenJDK (Eclipse only officially supports the former, but the latter mostly works).

Answer 6

I solved it by created a symbolic link java in /usr/bin that points to the VM.

Steps :

1. Downloaded the appropriate version of Oracle's JDK from http://www.oracle.com/technetwork/java/javase/downloads/index.html?ssSourceSiteId=otnjp

2. extract it to any folder. For example :

   tar zxvf ~/Downloads/jdk-8u5-linux-x64.tar.gz ~/DEV

3. create symbolic link with name java :

   cd /usr/bin

   ln -s ~/DEV/jdk1.8.0_05/bin/java java
