问题


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.

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.

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

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




回答4:


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.




回答5:


I have had this problem a few times...

  1. Add the IDEA_HOME/bin to your PATH Make sure JAVA_HOME & other variables are correct.

then run it from the terminal:

$ idea projects-name;

OR 2: navigate into the IDEA_HOME/bin and run it from there.




回答6:


Actually, you can configure the JAVA_HOME in bash. But, IDEA use javac and java from standard bin folders. So, you have to configure like this.

  • Download the JDK to home(~) folder
  • extract the zip file
  • use these command to mv to jvm folder under /usr/lib/jvm

    sudo mv -r ~/jdk-xx-version /usr/lib/jvm
    
  • use these commands to configure the JAVA_HOME

    sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk-xx-version/bin/java" 1 
    sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk-xx-version/bin/javac" 1 
    sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/lib/jvm/jdk-xx-version/bin/javaws" 1
    



回答7:


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.

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

This might not be the root cause for the original question, but it is the top hit when searching for this error:

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.

Short answer: If you were upgrading IDEA and run into this error and are using JBRE (JetBrains Runtime), export your previous runtime path to JAVA_HOME to load up the latest version of IDEA and allow the import wizard to copy configs over.

  • The issue appears on my development environment when there's no default JAVA_HOME installed.
  • I updated from 2019.2 to 2019.3, which causes the latest version of IDEA to temporarily have no config files.
  • This would mean there would be no 'valid Java runtime'.

Solution

  1. Look into your previous configuration and lookup what runtime you're using:

% cat ~/.IntelliJIdea2019.2/config/idea.jdk /home/username/.IntelliJIdea2019.2/config/jdks/jbrsdk-8u232-linux-x64-b1638.3

  1. In my case above it is jbrsdk-8u232-linux-x64-b1638.3 and the path is as shown above. Export that temporarily as JAVA_HOME.

EXPORT JAVA_HOME=/home/username/.IntelliJIdea2019.2/config/jdks/jbrsdk-8u232-linux-x64-b1638.3

  1. Run idea &.

You should now have the first time run dialog show up to copy the config over, and you won't need to export the variable again.
