Chris,

Yes it works without -XstartOnFirstThread.

Hi Yiguang


Would you be able to redo a clean install with 
<extraJvmArgs>-Xmx1024M -XstartOnFirstThread -Dconnection.string="${db.connection.string}" -Ddb.driver=${db.driver}</extraJvmArgs>

i.e. withouot the -XstartOnFirstThread, but with the extra memory setting. This option doesn't work on Windows, so I'm wondering if all you required was the memory max.
Cheers,
Chris

In a way, the mvn -pl <modulename> clean install command you did earlier last week is the same as cd <modulename> & mvn clean install

And I didn't notice a memory surge during the process). Will look at the pom file to see how to do it by individual modules. (I am new to mvn). It would be great if you can show me how to divide mvn clean install into more steps for building the STEP.
