Eclipse -vm option trouble - java

I'm having trouble setting up a new eclipse installation with the -vm option. I'm using the eclipse.ini file below (which has worked in the past). I need this for the m2eclipse plugin. Currently, if I include the -vm option eclipse fails to start.
Any idea what the problem is with this?
-startup
plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519
-vm
C:\Program Files\Java\jdk1.6.0_20\bin\javaw.exe
-showsplash

-vmargs
-XX:PermSize=256m
-XX:MaxPermSize=512m
-Xms128m
-Xmx1024m

Are you using a 64bit version of Eclipse with a 32bit JVM?

I'm guessing its the space in the Program Files part of the path. The below example works fine for me. Can you try to install the JDK in c:/apps and see if the script below works for you?
-startup

Pointing eclipse to JRE 1.7 instead of 1.6

I am getting error whenever I click eclipse icon that version 1.6 of the jvm is not suitable for this product. Version 1.7 or greater is required.
My other java applications in the system are using JRE 1.6 so I dont want to change that.
I have JDK 7 in my system as well but how can I point my eclipse to JDK 1.7 instead of default 1.6.
Thanks
You have several options.
Since you want to default to Java 1.6 for most of your other applications, I'd suggest modifying your Eclipse.ini:
https://wiki.eclipse.org/Eclipse.ini
EXAMPLE:
-startup
plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.100.v20110502
-product
org.eclipse.epp.package.java.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vm
C:\Java\JDK\1.8\bin\javaw.exe
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx1024m

Eclipse Not Working

Actually I downloaded the Android SDK from their site it was a bundle for android development and it was working fine. Then I downloaded the Netbeans from Java official site. It said it requires JDK7 so I downloaded that too. Now the Net Beans is working fine but eclipse displays this really long message box saying that Java was started but returned exit code 1 and then followed by some gibberish
My eclipse configuration file has the following text in it:

Add '-XX:-UseCompressedOops' to the eclipse.ini

Anyone have any suggestions? I tried changing:

to
-Dosgi.requiredJavaVersion=1.7
-Xms1024m
with no luck
One reason is that your -Xms parameter (initial heap size) defines a larger heap size than the -Xmx parameter (maximum heap size), you should fix it. If after fixing it the problem remains try to revert to the original eclipse.ini file and apply the parameters one by one to see which is the other 'wrong one'.
You seem to have changed a lot of things in one go.
As a general strategy, I would suggest reverting to the original settings, and then make the changes one at a time, starting with the most important one ... or the one that is most likely to work.

Regarding slow performance of eclipse

I am using eclipse 3.7 indigo , the issue that I am facing is when I start my eclipse my machine gets too slow even the eclipse get hang some times in between , the settings of my eclipse.ini file is below..
-startup
plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.100.v20110502
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx512m
please advise how to overcome from this..!!
Change this values to the higher ones:
--launcher.XXMaxPermSize 256m
-Xms40m
-Xmx512m
Perhaps this will help? I mean, I don't know the specs of the machine you're on, but this is nice on less powerful machines.
What are the best JVM settings for Eclipse?
Check with the eclipse.ini file and add the following java parameters and values.
-vmargs
-Dosgi.requiredJavaVersion=1.6
-Xmn128m
-Xms1024m
-Xmx1024m
-Xss2m
-XX:PermSize=256m
-XX:MaxPermSize=256m
-XX:+UseParallelGC
This worked for me. Might help.

Eclipse fails to create JVM after defining --launcher.XXMaxPermSize in eclipse.ini

I was using Eclipse and I got java.lang.OutOfMemoryError: PermGen space error. In Eclipse FAQ it says I should add these lines to eclipse.ini:
--launcher.XXMaxPermSize
[xxx]m
where xxx is the memory size I want to use (I tried 256). But after I do this I get Failed to create Java Virtual Machine error on Eclipse startup. What should I do to get it working?
My eclipse.ini file before editing:
-startup
plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.100.v20110502
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
--launcher.defaultAction
openFile
-vmargs
-Xms40m
-Xmx1024m
You need to adjust your eclipse.ini to include the argument -XX:MaxPermSize + specify a specific JVM for Eclipse to run on by adding the -vm option just before the -vmargs option. Ex:
-vm
C:\Java\JDK\1.6\bin\javaw.exe (The exact path to javaw.exe)
-vmargs
-Xms40m
-Xmx1024m
The -vm option and its value (the path) must be on separate lines.
A complete example:
-startup
plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.100.v20110502
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vm
C:\Java\JDK\1.6\bin\javaw.exe
-vmargs
-XX:MaxPermSize=256m
-Xms40m
-Xmx768m
Your eclipse.ini should be:
-XX:MaxPermSize=256m
