Ubuntu – Desktop link to Eclipse

eclipsejava

I was tring to install eclipse on ubuntu. What I did: I unzipped the tar archive of eclipse. I tried to start eclipse from the command line – like this – ./eclipse. It works. But then I tried to create a desktop icon with: gnome-desktop-item-edit ~/Desktop --create-new. In a new icon I showed the path to the eclipse executable which I could launch from the command line. But then eclipse does not start stating:

A Java Runtime Environment (JRE) or Java Development Kit (JDK)
must be available in order to run Eclipse. No Java virtual machine
was found after searching the following locations:
/home/artem/eclipse/jre/bin/java
java in your current PATH

The same message appears if I try to launch eclipse by double-clicking its original launcher. So it starts from the terminal but not from the desktop (it does not start when double-clicked)
And also I get a message in the terminal (at some stage it appeared):

(gnome-desktop-item-edit:8998): Gtk-WARNING **: Attempting to store changes into `/root/.local/share/recently-used.xbel', but failed: Failed to create file '/root/.local/share/recently-used.xbel.DSV8LW': No such file or directory

I am using Ubuntu 12.04 x32 and eclipse Juno.

PS. PATH variable points at jdk/bin and JAVA_HOME – to the jdk folder
PSS. I actually set the environment variables through .bashrc file(JAVA_HOME and PATH)

Best Answer

Create a file "eclipse.desktop" or similar, just be sure to have the .desktop extension.
Open File with a texteditor (gedit for instance)

paste following code into the file:

[Desktop Entry]
Version=1.0
Type=Application
Terminal=false
Exec=/home/path/to/eclipse/eclipse --clean -vmargs -Dfile.encoding=UTF-8 -Xmx1024m -Xms256m -XX:MaxPermSize=256m
Name=Eclipse JEE IDE
Icon=/home/path/to/eclipse/icon.xpm

Be sure to replace "/home/path/to/eclipse/" with your path to your eclipse installation folder.
Save the file
Make the file executable and copy it whereever you want an eclipse starter.

Happy Coding!

Ubuntu – How to create a .desktop file to launch eclipse

I had the same problem.

The next eclipse.desktop file works in Ubuntu 14.06 x64.

[Desktop Entry]
Encoding=UTF-8
Name=Eclipse
Comment=Eclipse IDE
Exec=/home/ivan/Eclipse/eclipse -vm /home/ivan/java/jdk1.7.0_25/bin/java
Icon=/home/ivan/Eclipse/icon.xpm
Categories=Application;Development;Java;IDE
Type=Application
Terminal=0

I didn't modify the eclipse.ini

Another solution is to modify the eclipse.ini file without modify your eclipse.desktop

My eclipse.ini:

-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20130327-1440.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.200.v20140116-2212
-product
org.eclipse.epp.package.standard.product
--launcher.defaultAction
openFile
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vm
/home/ivan/java/jdk1.7.0_25/bin/java
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.6
-XX:MaxPermSize=256m
-Xms40m
-Xmx512m

The -vm option and its value (the path) must be on separate lines.

Ubuntu – Can’t reset the JAVA_HOME to new Open JDK 11 Java installation

To Answer the question

The answers and some comments focus on how to set JAVA_HOME to version 11 but the question is partly about "where is version 8 being set?". To answer that see:

`grep`ing all files for a string takes a long time

Use this command:

$ sudo grep -rnw --exclude-dir={boot,dev,lib,media,mnt,proc,root,run,sys,/tmp,tmpfs,var} '/' -e '/usr/lib/jvm/java-8-oracle' | grep JAVA_HOME

/etc/profile.d/jdk.sh:4:export JAVA_HOME=/usr/lib/jvm/java-8-oracle
/etc/profile.d/jdk.csh:4:setenv JAVA_HOME /usr/lib/jvm/java-8-oracle
/home/rick/.gradle/daemon/4.6/daemon-14831.out.log:53:20:45:23.553 [DEBUG] (... SNIP ...) /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/lib/jvm/java-8-oracle/bin:/usr/lib/jvm/java-8-oracle/db/bin:/usr/lib/jvm/java-8-oracle/jre/bin (... SNIP ...) Configuring env variables: {PATH=/home/rick/bin:/home/rick/.local/bin:/mnt/e/bin:/mnt/e/usr/local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/lib/jvm/java-8-oracle/bin:/usr/lib/jvm/java-8-oracle/db/bin:/usr/lib/jvm/java-8-oracle/jre/bin,  (... SNIP ...)

This is what my system returns. Yours will likely be different. To make a long story short the culprit is /etc/profile.d/jdk.sh:

$ cat /etc/profile.d/jdk.sh

setenv J2SDKDIR /usr/lib/jvm/java-8-oracle
setenv J2REDIR /usr/lib/jvm/java-8-oracle/jre
setenv PATH ${PATH}:/usr/lib/jvm/java-8-oracle/bin:/usr/lib/jvm/java-8-oracle/db/bin:/usr/lib/jvm/java-8-oracle/jre/bin
setenv JAVA_HOME /usr/lib/jvm/java-8-oracle
setenv DERBY_HOME /usr/lib/jvm/java-8-oracle/db

You probably surmise /etc/profile.d/jdk.csh needs changing too. Indeed it contains the exact same contents as /etc/profile.d/jdk.sh

To address the XY problem

There is a better way than going through files line by line and changing an 8 to an 11.

The easiest method is using Java installer. From this Ask Ubuntu Q&A: Setting JDK 7 as default

To get a list of your installed Java platforms, run the following command from the terminal:

sudo update-alternatives --config java

This will give you a list output similar to this:

There are 2 choices for the alternative java (providing /usr/bin/java).
   Selection    Path                                           Priority   Status
