GWT eclipse plugin 3.0.0 install error

[jkwiu]

I am using Eclipse 2020-06, Java 1.8, and GWT 2.8.0. However, the installation link for GWT Plugin 3.0 in the Eclipse Marketplace (https://storage.googleapis.com/gwt-eclipse-plugin/v3/release) is broken, and the plugin is not installing properly. Does GWT no longer support GWT 2.8.0? I hope the link will be restored.

I'm afraid that we never saved 3.0.0 and... it is gone. @niloc132 can you confirm?
While I'm not sure that Eclipse 4.0.0 will work with eclipse 2020-06 (it should work on Eclipse >= 2022-09) it definitely supports GWT 2.8.
As a matter of fact, GWT 2.8 is supported by all 4.x.x plugins

Unfortunately, we never deleted this - we never had access to it to begin with. I suspect that someone at Sencha took it upon themselves to delete this old version now that new versions were being published.

Separately we've been asked to also ship 2.8.1 as an available SDK version - I think we could include 2.8.0 as well if that would resolve this for you. Note that you don't need to use the SDK version from the plugin, but can download your own old SDK releases from https://www.gwtproject.org/versions.html and configure the plugin to use it from where you unpack it.

Its true that we didn't save a backup copy, but I didn't think they would proactively delete this for us.

Thanks for your reply. I have tried to build and compile my GWT project many times using GWT Plugin 3.0 and GWT 2.8.0 SDK, but all attempts failed.

Finally, referring to @protoism , @niloc132 suggestion, I succeeded in building my project with GWT Plugin 4.0 and GWT 2.8.0. I properly set up my build environment with the latest version of Eclipse, and the compilation was completed successfully.

Thank you all!
