I'm getting runtime these errors but at runtime, not with an IDE.
My application will not run unless I add google-collect-
snapshot-20080530.jar to the classpath.
I'm using JRE 1.6, and the recently downloaded guice-
snapshot20081016.zip.
I did not build it myself.
I've checked a few times and can't see what I'm doing wrong.
Perhaps there's a jarjar problem with the snapshot creation?
Gory details below:
The error I get is
java.lang.NoClassDefFoundError: com/google/common/base/Preconditions
at com.google.inject.multibindings.Multibinder$RealMultibinder.<init>
(Multibinder.java:178)
Line 178 is a reference to checkNotNull, which is one of the two
static imports from com.google.common.base.Preconditions.
I have these classes in the servlet applications WEB-INF/lib
directory:
guice-assistedinject-snapshot20081016.jar
guice-commands-snapshot20081016.jar
guice-multibindings-snapshot20081016.jar
guice-privatemodules-snapshot20081016.jar
guice-servlet-snapshot20081016.jar
guice-snapshot20081016.jar
guice-spring-snapshot20081016.jar
guice-struts2-plugin-snapshot20081016.jar
guice-throwingproviders-snapshot20081016.jar
If I add this file to the classpath, the error doesn't happen:
google-collect-snapshot-20080530.jar
Here is the error:
