titan 0.5 throws IllegalAccessError because of guava 18.0

[Vikraman Choudhury]

Hi,

While trying to update my scala project to titan 0.5, I got a java
exception at startup, with the following stacktrace.

[error] (run-main-0) java.lang.IllegalAccessError: tried to access method com.google.common.base.Stopwatch.<init>()V from class com.thinkaurelius.titan.graphdb.database.idassigner.StandardIDPool
java.lang.IllegalAccessError: tried to access method com.google.common.base.Stopwatch.<init>()V from class com.thinkaurelius.titan.graphdb.database.idassigner.StandardIDPool
at com.thinkaurelius.titan.graphdb.database.idassigner.StandardIDPool.waitForIDRenewer(StandardIDPool.java:118)
at com.thinkaurelius.titan.graphdb.database.idassigner.StandardIDPool.close(StandardIDPool.java:214)

at com.thinkaurelius.titan.graphdb.database.StandardTitanGraph.shutdown(StandardTitanGraph.java:155)

After checking the sbt dependency graph, I noticed that titan's guava
15.0 dependency was being evicted by guava 18.0 which was being pulled
in by a different package.

I managed to get it working by forcing guava to 15.0 in build.sbt.

"com.google.guava" % "guava" % "15.0" force()

Just FYI.

This is becoming a pain. 

Any chance of titan upgrading to guava 18.0?

[Matthias Broecheler]

yes, we will do this for 0.9.

You can just go into line 117 of StandardIDPool and change it to:

Stopwatch sw = Stopwatch.createStarted();

[Alireza Rezaei Mahdiraji]

How do we do that in Maven based project?

Cheers,

I don't know if you can use this, but I've forked a version of Titan with this at:

https://github.com/nuixkeith/titan

I'll see if this can be pushed back into the Titan project.
