how do I set eclipse.ini -vm option ?

Question

I installed maven plugin for eclipse, then I get an error like below:

please make sure the -vm option in eclipse.ini is pointing to a JDK

how to use -vm option to point to my jdk in eclipse.ini?

Answer 1

You have to edit the eclipse.ini file to have an entry similar to this...

C:\Java\JDK\1.5\bin\javaw.exe (your location of java executable)
-vmargs
-Xms64m   (based on you memory requirements)
-Xmx1028m

also remember that in eclipse.ini, anything meant for eclipse should be before -vmargs line and anything for JVM should be after -vmargs line.

Answer 2

I know that there exists an command line option -vm to specify the path to executable of the java runtime. This may be the same as in eclipse.ini.

Answer 3

let me share my solution

-vm 
D:/work/Java/jdk1.6.0_13/bin/javaw.exe
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256M
-framework
plugins\org.eclipse.osgi_3.4.3.R34x_v20081215-1030.jar
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx512m

Answer 4

There is a wiki page here.

There are two ways the jvm can be started: by forking it in a seperate process from the eclipse launcher, or by loading it in-process using the JNI invocation API.

If you specify -vm with a path to the actual java(w).exe, then the vm will be forked in a separate process. You can also specify -vm with a path to the jvm.dll so that the vm is loaded in the same process:

-vm
D:/work/Java/jdk1.6.0_13/jre/bin/client/jvm.dll

You can also specify the path to the jre/bin folder itself.

Note also, the general format of the eclipse.ini is each argument on a seperate line, it won't work if you put the "-vm" and the path on the same line.

Answer 5

-vm

C:\Program Files\Java\jdk1.5.0_06\bin\javaw.exe

remember, no quotes. no matter if your path has spaces. (opposed to command line execution)

see here: Find the JRE for Eclipse

Answer 6

Not sure if something has changed, but I just tried the other answers regarding entries in "eclipse.ini" for Eclipse Galileo SR2 (Win XP SR3) and none worked. Java is jdk1.6.0_18 and is the default Windows install. Things improved when I dropped "\javaw.exe" from the path.

Also, I can't thank enough the mention that -vm needs to be first line in the ini file. I believe that really helped me out.

Thus my eclipse.ini file starts with:

-vm
C:\Program Files\Java\jdk1.6.0_18\bin

FYI, my particular need to specify launching eclipse with a jdk arose from my wanting to work with the m2eclipse plugin.

Answer 7

Anything after the "vmargs" is taken to be vm arguments. Just make sure it's before that, which is the last pices in eclipse.ini
