I've downloaded Intellij ultimate version and I am trying to open idea.sh but it tells me this:

"JDK Required: 'tools.jar' seems to be not in IDEA classpath. Please ensure JAVA_HOME points to JDK rather than JRE."

I don't know what to do, can anybody help? I've searched in Google but couldn't find anything.

all I know is that I have jdk because when I use java -version it tells me something, but I can't locate the path or somethings wrong

echo $JAVA_HOME returns

/usr/lib/jvm/java-7-openjdk-amd64/

this happened after I've installed java-7-openjdk before that I had java-9-oracle and I thought it was jdk but there were still problems

I've tried without sudo and everythings seems fine.

Seems like you don't have de JDK, only the JRE. Try run this:

sudo apt-get install openjdk-7-jdk

The java you see on java -version is installed via the openjdk-*-jre package and it's able to run java applications. But to develop java (and run most of java IDEs) you need the openjdk-*-jdk packages.

If you're still having trouble, try this links:

  • i have that and echo $JAVA_HOME returns: /usr/lib/jvm/java-7-openjdk-amd64/ – Nika Garibashvili Sep 20 '15 at 11:20
  • That's strange. I have a recently installed Freya. I just installed the openjdk-7-jdk and set the JAVA_HOME to the same folder as yours. Downloaded the IDEA Community Edition 14 and all worked fine. Try apt-get purge the openjdk packages and reinstall them. Also, see if your previous installation from oracle have been completed removed as it may have conflicting configs with openjdk. – Thiago Jedi Sep 21 '15 at 15:45
