Error compiling with trunk and guava-gwt-18.0.jar

[John Huss]

I built GWT trunk locally today and I'm trying to compile my app that uses Java 8 lambdas along with guava-gwt-18.0,jar.  When I compile I get an error thrown because of guava:

     [java]    Tracing compile failure path for type 'com.google.common.collect.GwtPlatform'

     [java]       [ERROR] Errors in 'jar:file:/Users/john/repos/styleware-net/Salondata/lib/guava-gwt-18.0.jar!/com/google/common/collect/super/com/google/common/collect/GwtPlatform.java'

     [java]          [ERROR] Line 38: The method createFrom(T[], int) is undefined for the type Array

     [java]    [ERROR] Aborting compile due to errors in some input files

     [java] Java Result: 1

For reference, this previously DID compile with an older version of GWT that I built in late January.

Thanks,

John

You need to use Guava from their master branch or a SNAPSHOT build. Guava will do a new release as soon das GWT 2.8 has been released.

Oh, I thought 19.0-rc2 (or even 19.0-rc1) was enough.

I would expect the RCs to work, the patch is already in the trunk for a while.

They have reverted the Array fix in the release branch of Guava 19 as they want it to be GWT 2.6 / 2.7 compatible. Guava 20+ will require GWT 2.8+

See GWT notes: https://github.com/google/guava/wiki/Release19

You could try to patch the guava-gwt.jar locally by yourself ... you need only apply this patch https://github.com/google/guava/commit/9e56ef17c335319d21f1f2c454176c9d32687a59 by editing a java source file in the jar and it should work... I did a similar patch for guava 17 and this works with gwt 2.7 and the latest snapshot for gwt 2.8 (both with Java7)! :-)
