GWTP Rebind throwing IllegalArgumentException (ProxyGenerator) after GWT 2.7.0 upgrade - gwt

Question

I'm trying to upgrade an older GWT 2.5.1 project that was semi-retrofitted with GWTP 1.0.2 to GWT 2.7.0, but but I'm running into an error I just can't figure out. I've googled and googled, I've rearranged project dependencies, and still I get the same error when doing a mvn gwt:compile, below:
Computing all possible rebind results for 'com.example.foo.client.administration.AdminPresenter.AdminProxy'

This is occuring for every presenter it appears - it's a fairly large project, and I'm seeing over a dozen versions of the same message, each regarding a different Presenter/Proxy.
One possible cause / twist is that the presenters / views / proxies were manually built / retro-fitted after the fact - it was previously a plain GWT project, and they used a separate GWTP-created project as an example. This has worked for the last 2 yrs using GWTP .7 - 1.0.2 on GWT 2.5.1, but somehow it appears to be breaking for the 2.7.0 upgrade.
I tried upgrading the project to GWTP 1.3.1, but it made no difference.
I've tried rearranging dependencies - gwt-user fist, gwtp-all first, it made no difference.
After a string of many of the previous errors, there are also a
java.lang.NoSuchMethodError: com.google.gwt.uibinder.rebind.UiBinderWriter.<init>(Lcom/google/gwt/core/ext/typeinfo/JClassType;Ljava/lang/String;Ljava/lang/String;Lcom/google/gwt/core/ext/typeinfo/TypeOracle;Lcom/google/gwt/uibinder/rebind/MortalLogger;Lcom/google/gwt/uibinder/rebind/FieldManager;Lcom/google/gwt/uibinder/rebind/messages/MessagesWriter;Lcom/google/gwt/uibinder/rebind/DesignTimeUtils;Lcom/google/gwt/uibinder/rebind/UiBinderContext;ZZLjava/lang/String;)V
error, which in other modules I've been able to fix by moving gwt-user to the top of the dependencies, but it isn't working here. It's hard to tell which errors are really breaking things, and ideally I'd fix them all.
I'm also getting another, certainly related error:

It is GWT-compiling in eclipse, but in regular dev mode I get this stacktrace:
