Support for Java 8 and AssertJ 3.x?

[bcalmac]

From the pom.xml dependency for assertj-core [2.1.0, 2.99.0] I infer that assertj-guava is not compatible with AssertJ 3.x and Java 8. Are there current plans to get it working?

I tried to see if it works anyway (assertj-guava 2.0.0 + assertj-core 3.2.0) and the following test:

    @Test
    public void assertjMultimapTest() {
        assertThat(ImmutableListMultimap.of(6, "Mickey", 6, "Minnie", 3, "Goofy"))
            .hasSameEntriesAs(ImmutableListMultimap.of(6, "Mickey", 6, "Minnie", 5, "Goofy"));
    }

fails with the exception below. It looks related to type inference changes from Java 8.

java.lang.NoSuchMethodError: org.assertj.core.error.ShouldContainOnly.shouldContainOnly(Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Iterable;)Lorg/assertj/core/error/ErrorMessageFactory;

@bcalmac I will release by the end of the year a new assertj-guava version (probably 3.0.0) compatible with assertj-core 3.x. version.

[bcalmac]

Good timing :-) If there's any way I can help, let me know.

[joel-costigliola]

Well, I was expecting someone to (rightfully) complain ;-)

AssertJ Guava 3.0.0 released.
Can you give it a try ?

[bcalmac]

My test case works now, thanks.

Thanks for the feedback 👍
