Not able to install GWT Plugin as of May 2018 in eclipse

Question

Please reply for both the issues.

Issue 1: The installation of GWT Plugin through eclipse marketplace was working fine until last month. But now as I check there is some issue. The URL http://storage.googleapis.com/gwt-eclipse-plugin/v3/release is not reachable. This url is used to install the plugin in eclipse.

Issue 2 Also I tried compiling the source code from https://github.com/gwt-plugins/gwt-eclipse-plugin . I am also pasting part of the log output for reference:

Answer 1

Just use https://github.com/gwt-plugins/gwt-eclipse-plugin

This is a fork of the old plugin, but is still maintained and has a bunch of extra features.

Look at the GitHub page for documentation (also in the form of videos).

Also available in Eclipse Marktplace: https://marketplace.eclipse.org/content/gwt-eclipse-plugin
