Selected directory is not a valid home for JDK - Intellij IDEA on Ubuntu

Question

After installing Intellij Idea 14, with OracleJDK 1.8 u25 (64 bit) on my 14.04 Ubuntu system, I cannot configure the Java SDK to use any JDK. When I navigate to Module Settings->SDK and click configure SDK, the add button, and then select /usr/java/jdk1.8.0_25 in the dialog, I get an error popup stating that "The selected directory is not a valid home for JDK."

I've checked the contents of the directory, which contains a bin folder with both java and javac inside, a lib folder and a jre folder.

I've tried selecting each of those in turn, to no avail, which I expected.

@A1ternat1ve Not a duplicate in the sense that accepted answer doesn't apply since the folder in question is a full jdk install, unlike as within that case. According to the answer, one of `bin`, `lib`, or `jre` was missing or incomplete. — Andrew Schade, May 08 '15 at 05:35

@Evan Thanks! That provided me with a solution to the question. I've posted an answer with the method I used. — Andrew Schade, May 08 '15 at 05:52
Check you installed the jdk (not only the jre) : sudo apt-get install openjdk-8-jdk — Remy Mellet, Aug 18 '16 at 08:57

I had the same problem, in my case I wasn't able to select any of the "openjdk" directories under /usr/lib/jvm/, I solved with:

sudo apt-get install openjdk-8-jdk

When restarting intellij it will find the path to the jdk automatically.

On ubuntu 16.04 I did not have a `/usr/local/java/` folder. This worked for me, however. Right after doing this IJ was able to let me select `/usr/lib/jvm/java-1.8.0-openjdk-amd64` – ferahgo Aug 12 '17 at 02:37

For the ones who run into this problem even though you select the right directory under /usr/lib/jvm, there is something you should know : The directories under /usr/lib/jvm are created when your system installs the minimum set of java tools. But it doesn't mean you have the development files available. You need to install the development files :

sudo apt-get install java-1.8.0-openjdk-devel

After installing this package, try to select the directory again and it should work.

This is especially necessary if you want to install any jdk8+, thanks @vdegenne – Zarathustra Nov 24 '18 at 12:42

Evan Knowles posted a link to https://askubuntu.com/questions/130186/what-is-the-rationale-for-the-usr-directory. It provided me with the solution to the problem.

Instead of using the JDK at /usr/java/jdk1.8.0_25, I instead used the JDK at /usr/local/java/jdk1.8.0_25. The reasons that this works rather than the other are explained in detail within the link.

I came across this error because I did not have JAVA_HOME set.

Adding export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64 (for openjdk 11 in my case) and export PATH=$JAVA_HOME/bin:$PATH to my ~/.bashrc and then running source ~/.bashrc solved the problem for me.
