Re: GWT 2.8.0-rc1 and closure compiler

I've always used the closure compiler with past versions (even with 2.8.0-beta1, which we have used in production already).

Now, to my surprise, it is no longer supported in GWT 2.8.0-rc1, as there's no mention to it in the release notes (http://www.gwtproject.org/release-notes.html).

We may want to add a note about it; but that was an experimental feature and those tend to come and go as experiments prove their value or not.

See https://gwt.googlesource.com/gwt/+/162ccc9c9112a09bf9ea046da95760f5f1886b72%5E%21/ for the rationale.

 

Now the compiler no longer supports the old closure compiler option, but has a new -X[no]closureFormattedOutput option.

It's not really new actually: https://gwt.googlesource.com/gwt/+/6fa611cf9ad7ffa077a7378a100a7ccbd95e3cb3%5E%21/

 

I'm guessing closure compiler is no longer integrated in GWT, but it still has the option to format for closure to a later (manual) usage of closure compiler.

I'm using the gwt-maven-plugin, which still uses beta1, but explicitly changing its dependencies to 2.8.0-rc1 for gwt-user, gwt-dev and gwt-codeserver artifacts, making it usable already for rc1.

I can't, however, pass the new option (I think there's no way to pass arbitrary compiler arguments with gwt-maven-plugin) until the maven plugin is updated.

What are the new instructions to keep using closure compiler?

There aren't (see comment about -XclosureFormattedOutput in the commit message that introduced it)

Do you really *need* it?
