Installing IDEA on Ubuntu 11.10

Question

I am trying to install IDEA on Ubuntu 11.10. First, I installed openjdk-7-jdk. Then I tried running the idea.sh file as instructed. However it complains:

ERROR: cannot start IntelliJ IDEA.
No JDK found to run IDEA. Please validate either IDEA_JDK, JDK_HOME or JAVA_HOME 
environment variable points to valid JDK installation.

Press Enter to continue.

Trying to echo these three variables prints an empty line to the screen. How (and to what values) do I set these variables and proceed with the installation? Thanks.

Answer 1

UPDATE:

It's recommended to use the bundled JetBrains Runtime on Linux to run IntelliJ IDEA. At the moment IntelliJ IDEA requires Java 8 to run on this platform. It's possible to switch to a system or some other Java version, please check the FAQ.

Original answer (obsolete):

It's recommended to use OpenJDK 1.7+ or Oracle JDK to run IntelliJ IDEA on Linux, OpenJDK 1.6 is strictly unsupported because of the known performance and visual issues.

Starting from IntelliJ IDEA 16, custom JRE is bundled with Linux distributions.

The tricky part is that Oracle JDK is no longer distributed via .deb packages and you can't just install it with apt-get or Ubuntu Software Center.

Their site is also confusing and you can easily download JRE instead of the JDK (which will not work as IntelliJ IDEA needs tools.jar that is missing from JRE package).

Here is the correct URL for the JDK downloads (version 1.6.0_29). From this URL download the appropriate .bin file, for example jdk-6u29-linux-i586.bin if you need 32-bit Java or jdk-6u29-linux-x64.bin for 64-bit version.

chmod +x jdk-6u29-linux-i586.bin
./jdk-6u29-linux-i586.bin

to install in the current directory.

Inside bin/idea.sh add the following on the second line:

export IDEA_JDK=/path/to/jdk1.6.0_29

Normally resides under /usr/lib/jvm/<YOUR_JDK>. Now IntelliJ IDEA should start fine under Oracle JDK 1.6.0_29. You can verify it in Help | About.

i also face a question... in firs day all works without problems, but then... i solve a problem: add to file idea.sh line with path to JDK IDEA_JDK="/opt/java/32/jdk1.6.0_45/"

add after 46 line

Answer 3

if you had install java ,try

type java

if you see like this

java is /usr/java/default/java

then you should edit .bash_profile,add

export JAVA_HOME=/usr/java/default

then execute

source .bash_profile

if you not install java,you should install manual or auto.

Answer 4

You install JDK 8 with:

sudo apt-get install openjdk-8-jdk

Then, sometimes the problem lies on the default version of JAVA you are running. For this, use update-alternatives to modify it:

sudo update-alternatives --config java

See how I did it:

$ 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-7-openjdk-amd64/jre/bin/java   1071      auto mode
  1            /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java   1071      manual mode
  2            /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java   1069      manual mode

Press enter to keep the current choice[*], or type selection number: 2
update-alternatives: using /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java to provide /usr/bin/java (java) in manual mode

And now Intellij IDEA 2016.3 is running fine.

Answer 5

You can set JAVA_HOME variable and add to your PATH, by doing the following. As root open up /etc/bash.bashrc and add the following to the end of the file.

JAVA_HOME=/usr/lib/jvm/java
export JAVA_HOME

When you reboot, try running the following:

$ echo $JAVA_HOME

Here is a bash script for developers that installs IDEA so that you can run it from the shell via idea.sh

It also:

• Tests if the operating system is running on VirtualBox
• If it runs on VirtualBox, tests if IdeaProjects is set up for sharing
• If yes, writes a mount command to the bootstrap script to automount projects from host to guest
• Also creates a script to mount and unmount idea projects on-the-fly
