maven error: can not create the java virtual machine
Hi,
I am a newbie to maven, this morning I followed maven install
documentation step by step and complete the maven install.
System: windows XP Professional sp2
Java Version: jdk1.6.0_02
Maven Version: 2.2.0
at first installed, under command line, I can run: mvn --version, it
seems Ok, and output like:
Java home: D:\Program Files\Java\jdk1.6.0_02\jre
System os Windows Xp and blablabla... no error, no warn
However after a while, I change my command line path to another disk
F, and run mvn --version again, it appears imcompatible initial and
maximum heap sizes sepcified error.
I follew this mail:
http://www.nabble.com/Incompatible-initial-and-maximum-heap-sizes-specified-td23284917.html
then changed my MAVEN_OPTS to this: "-Xms256m -Xmx256m"
run mvn --version again, then it output:
invalid initail heap size: -Xms256m -Xmx256m
can not create the java virtual machine
this is my environment variable setting, is there some wrong in it?
======================================================================
System environment variable:
path ------

JAVA_HOME D:\Program Files\Java\jdk1.6.0_02
M2_HOME D:\Program Files\apache-maven-2.2.0
M2 %M2_HOME%\bin
MAVEN_OPTS "-Xms256m -Xmx256m"
======================================================================
Should I go back to install old maven version as 2.1.0? I like to use
the latest version of software, and my classmate says it is not a good
habit, because the latest version means
unstable performance.
Who can give me some suggestion, please? Thanks a lot!
ps: please forgive my poor english vocabulary

Note the quotes around the value of MAVEN_OPTS! Try again after doing
set MAVEN_OPTS=-Xms256m -Xmx256m
