Question

I installed Java 7 JDK (jdk-7u9-windows-x64.exe) and started up Eclipse Indigo to try a statement using the new diamond syntax. It does not compile.
I have added jdk1.7.0_09 in Preferences – Java – Installed JREs.
Under Preferences – Java – Compiler I wanted to set 1.7 compliance level, but my drop-down list only contains 1.3 – 1.6. How can I get 1.7 to appear here?
Version: Indigo Release Build id: 20110615-0604

Copied from eclipse page:

Download Eclipse 3.7SR2 for out of the box support. Or, follow the
steps below to get the JDT source code in an earlier build and launch
a runtime workbench which will contain Java 7 features.

Edit:
Eclipse indigo sr2 can be downloaded: here
