OutOfMemory Error

[Eran Chinthaka]

Title: Message

I was using maven site command. At one time it is saying copying some number of files. But the problem is the number of files this is copying seems to be increasing, without much  of a change to the code or relevant xml files. And another things is after transforming user documents, it is saying an OutOfMemoryError. For maven to come to this state, it has taken 116 minutes. Please help me to fix this.   Eran Chinthaka
