[guava incompatibility] when is the next milestone?

[or-shachar]

The latest release(https://github.com/google/jimfs/milestone/2) pretty old and is incompatible with guava 20 even...
I saw Guava was updated several time since the last release.

What's holding us from releasing 2.0 (https://github.com/google/jimfs/milestone/3)?

What exactly is incompatible?

[swankjesse]

Jimfs requires an obsolete version of Guava that is incompatible with current releases. Running Jimfs with current versions of Guava causes Jimfs to crash hard:

java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkArgument(ZLjava/lang/String;[Ljava/lang/Object;)V
	at com.google.common.jimfs.WatchServiceConfiguration$PollingConfig.<init>(WatchServiceConfiguration.java:66)

Scratch that; this one is not Jimfs’ fault. I’ve got another project on my classpath (kotlin-compiler 1.2.21) and it embeds an even older version of Preconditions.class that doesn’t interop with Jimfs. Ick.
