Answer 1

I had the same problem, and found a lot of fixes for Windows but not for Ubuntu.

This seems to be working for me in Ubuntu 12.04, with Eclipse Juno:

I followed the instructions here to install Sun Java JDK 6: http://www.devsniper.com/ubuntu-12-04-install-sun-jdk-6-7/

(if you already have Sun Java JDK installed, then maybe just try the parts labelled "Choose default java" and "Verify the symlinks".)

Then I added the following to my eclipse.ini file:

-vm
/usr/lib/jvm/jdk1.6.0_32/bin/java

Note that it seems you have to put the new line in, and it must go in the right place in the file, after --laucher.defaultAction but before -vmargs. So my full eclipse.ini now reads:

-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.200.v20120522-1813
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
-Dandroid.sdk.path=/home/gguser/android-sdk-linux
openFile
-vm
/usr/lib/jvm/jdk1.6.0_32/bin/java
-vmargs
-Xms512m
-Xmx512m

That may be the your default Java installation, but it doesn't mean that's your only Java installation. Assuming you haven't installed any by hand, you should look in Synaptic to see if you have sun-java6-jre installed in addition to sun-java6-sdk (note that sun-java6-jre installs in a subdirectory of where sun-java6-sdk installs. You may also have OpenJDK installed, et al.

Next, be aware that Eclipse does NOT use $JAVA_HOME to find a JDK to run under. The VM to use is defined in the eclipse.ini config file, and if one isn't defined there, it looks for a JRE installed under its own directory.

Solved: m2eclipse: Eclipse is running in a JRE, but a JDK is required
