Update guava to latest version

[SchulteMarkus]

Please update guava to latest version. For time being, querydsl is using version 14.0;latest stable is 18.0[1].

There are known bugs meanwhile fixed in guava18.0. In special, 14.0 is not deployable to JavaEE7 containers[2].

I understand your concern, and I wish I could sticky this, but a little explanation here:

Querydsl code doesn't use all that much Guava code, so if you use Guava 18.0 it should work, but we compile against 14 because of Batoo JPA.
We are probably going to try to update the dependency soon, but for now we can't as you could see in your pull request, and as I explained in this issue:
#835

I hope this answers your question, and thanks for letting us know!

I understand - and this problem is not a big deal, anyhow.

As a workaround for others:

• Exclude ("exclusions") guava as a querydsl dependency
• Import guava > 16.0 as an own entry in your pom.xml

The next release is a minor release, so dropping official Batoo support in the tests could be considered which would give as the possibility to upgrade Guava. What do you think?

Batoo JPA is not actively maintained anymore and the Guava upgrade pull requests for Batoo have not been accepted.

In my opinion this is fine by me.

Thanks!

Released in 3.5.0

How strongly is querydsl (4.0) dependent on Guava? Would it be OK to exclude it completely for a JPA (Eclipselink) & j2EE7 (Glassfish) application?

[Shredder121]

We use quite a few features to make up for the Java 6 to 7 bridging(Objects), and for things that should exist in a sane way in the JDK by default (CharMatcher, Sets, Maps).
If you look for Querydsl without Guava I think building it yourself and removing it shouldn't be that much work (?)

[Shredder121]

Oh, just remembered, we use the Function interface, so unfortunately I think it requires quite some work.
