what is the function of gwt-unitcache directory (not under target directory)?

[tong123123]

I try to run mvn:clean install and the content in gwt-unitCache (not the one in target directory, but the one directly under the project folder) will not changed, so what is its use? Could I not commit this folder in svn if it is not important?

AFAICT, gwt-maven-plugin will only create things under target/ (unless told it otherwise). If you have a gwt-unitCache folder sibling to the target/ folder, it has probably been creating when launching the DevMode from within Eclipse (rather than "mvn gwt:run").

Anyway, as its name suggests, it's a "cache", you shouldn't generally commit it to your SCM.
