Guava version which is compatible with GWT 2.9.0

[pratik thaker]

Hi Team,

We were using GWT 2.7.0 and guava-18 earlier.

Recently we have upgraded to GWT 2.9.0 and we are facing issue in using below classes from guava,

com.google.common.collect.ComparisonChain

com.google.common.collect.Ordering

I tried upgrading to guava-gwt-29.0-jre.jar but for that we are getting below error,

                            [ERROR] Line 373: ComparisonChain cannot be resolved

     [java]             [ERROR] Line 8: The import com.google.common cannot be resolved

     [java]             [ERROR] Line 374: Ordering cannot be resolved

     [java]             [ERROR] Line 7: The import com.google.common cannot be resolved

Can you please help me compile ?

I just realized that this might be because I had remove below line from my gwt.xml file,

<inherits name="com.google.common.collect.Collect"/>

I am checking now.

Hey,

     [java]    [ERROR] Hint: Your source appears not to live underneath a subpackage called 'client'; no problem, but you'll need to use the <source> directive in your module to make it accessible

Did you try making the source accessible?

Hi Shawn,

It is because of org.checkerframework.checker.nullness.qual.Nullable

I don't know how to make it available.

Can you help me with that ?

I tried with guava 19,20 etc. but all of them are having one or another issue.

It looks like you're not using any tooling to resolve your dependencies (Maven, Gradle, Ivy, Coursier, you name it), so you have to grab the transitives manually (and resolve version conflicts).

Compare the dependencies block (lower right) between https://search.maven.org/artifact/com.google.guava/guava-gwt/21.0/jar and https://search.maven.org/artifact/com.google.guava/guava-gwt/29.-jre0/jar; you need https://search.maven.org/artifact/org.checkerframework/checker-qual/2.11.1/jar now.

I would highly recommend automating this through dedicated tooling though.
