The GWT SDK contains the core libraries and compiler that you need to write web applications. See the Release Notes for this latest version.
Note - This download contains the standalone GWT SDK and tools only. If you're using Eclipse, we suggest that you download and install the GWT Eclipse Plugin instead.
Plugin for Eclipse (incl. SDKs)
The GWT Eclipse Plugin provides IDE support for GWT projects.
Note - This download includes Eclipse tools as well as the option to install the GWT SDK.
Note - GWT release candidates are not bundled with the GWT Eclipse Plugin. The GWT Eclipse Plugin's version of GWT might also not always be up-to-date.
