Check that your system is not subject to the JRE XP issue. There was gap in JRE packaging by Msoft..see http://www.microsoft.com/windowsxp/evaluation/news/jre.mspx The result is on some installations of XP the JRE has issues.
as you explicitely path C:\CSI\eclipse_workspaces\CSI\csi_build\src\tools\jdk\jdk1.5.0_04\bin; in one instance you are OK. however you might look closer at the JRE as packaged with XP. -----Original Message----- From: Matthew Wheaton [mailto:[EMAIL PROTECTED] Sent: Friday, December 02, 2005 1:09 PM To: Maven Users List Subject: Re: M2 : Having problems with a javac on a very simple build of my first M2 project. Hi Bill, I have nothing else, in fact, in my system environment there is no JAVA_HOME at all, and absolutely no java references in the system path.
