Intellij IDEA Java classes not auto compiling on save

Yesterday I switched to Intellij from Eclipse.

I am using jRebel with Websphere Server 7 as well.

Everything now seems to be working somewhat fine, except that when I modify a Java file, and hit save, Intellij does not re-compile the file, in order for jRebel to pick it up.

The eclipse "Build Automatically" feature resolved this issue.

In Intellij, I have to hit CTRL + SHIFT + 9 to re-compile the relevant class for jRebel to pick it up. If changes are done across two files, I have to do this on each and one of them and since Intellij uses the save all mechanism, its pretty hard to know what to recompile manually which I am not really interested in doing either.

Isn't there a way to make Intellij to do this on its own?

For IDEA 12+ releases we can build automatically the edited sources if we are using the external compiler option. The only thing needed is to check the option "Make project automatically", located under Compiler Settings. Compiler Settings

For versions older than 12, you can use the EclipseMode plugin to make IDEA automatically compile the saved files. See: for more tips when migrating from Eclipse.
