Answer 1

First of all you need to set your JAVA path in .bashrc file. goto cd ~ open .bashrc,vi .bashrc add a line at the end export path="path/to dir:$path" do source .bashrc for changes to take effect.

Then open your eclipse.ini file(if you want to locate eclipse.ini do whereis eclipse). open eclipse.ini,then add a line

-vm
"path/to/bin/of/open-jdk"

Answer 2

You need to add the JDK to your PATH.

Answer 3

I solved this error message by adding jre path in to eclipse.ini.To solve the error like this,your machine should have java installed. In my setup eclipse.ini is in eclipse-jee-mars-linux-gtk-x86_64-5.0.0/eclipse folder.

Add,

-vm /home/user/Documents/Softwares/jdk-8u202-linux-x64/jdk1.8.0_202/jre/bin

at the top of the file.

In here /home/user/Documents/Softwares/jdk-8u202-linux-x64/jdk1.8.0_202 is my JAVA_HOME

For me, directing JDK path to -vm didn't work.I had to put the jre/bin path which is inside jdk folder.

Answer 4

I tried editing .profile, .bashrc, to no avail. (I'm trying to use eclipse by clicking an icon, NOT by executing it from a bash shell).

SOLUTION: I copied my /home/denise/jdk1.7.0_25/jre to /home/denise/dev//jre

which is a stupid solution because it defeats the purpose of having a .profile or .bashrc.

and no, there was no .pam_environment file

peace!

Answer 5

You need to have a Java environment that can execute the Java instructions in Eclipse for it to run.

Install a suitable Java package in the package manager, and try again. Note that Eclipse does not require a JDK, a JRE is enough.
