Errai 2.4.3.Final and GWT 2.6.0 anyone?

hr.stoyanov Feb 20, 2014 12:53 AM

Hi all. Has anyone succeeded using Errai 2.4.3 with GWT 2.6.0? I decided to use the newly released GWT 2.6.0 with Errai 2.4.3.Final and started getting errors like these:

So, I checked my Gradle build if I am accidentally introducing some GWT 2.5.1 dependency, but could not find any. My concerns is that Errai 2.4.3. Final is hard-wired to GWT 2.5.1, preventing upgrade to GWT 2.6.0. Indeed, take a look at this dependency:

Hi Hristo,

This is an issue with GWT's caching system. It can happen when you switch between versions of the GWT library jars. To fix it, find and delete all gwt-unitCache directories within your project(s). Our example Maven POMs are set up to delete these directories when you clean; you could do the same with your Gradle build.

GWT 2.6.0 compiles with the Java 7 source level by default, and according to this mailing list thread, Guava 14 can't be compiled as Java 7 source code. You can fix this by updating to Guava 15.

So, I checked my Gradle build if I am accidentally introducing some GWT 2.5.1 dependency, but could not find any. My concerns is that Errai 2.4.3. Final is hard-wired to GWT 2.5.1, preventing upgrade to GWT 2.6.0. Indeed, take a look at this dependency:

Yes, Errai 2.4.3 (also 3.0 currently) declares a dependency on GWT 2.5.1, but in Maven you can override that in your POM's <depencencyManagement> section. Gradle probably has a similar feature for overriding the versions of transitive dependencies.

Hope that helps,
Jonathan
