Is it possible to use guava in the client side code of a gwt web application? If so, how does one add guava to an Eclipse project?
I've added both the guava-10.0.1 and guava-gwt-10.0.1 jars to my build path and have added the source attachments to each but I still get this error:
No source code is available for type com.google.gwt.thirdparty.guava.common.base.Predicate; did you forget to inherit a required module
OK, look at your import line. Does it look like this?
import com.google.gwt.thirdparty.guava.common.base.Predicate; That's wrong. Change it to:
import com.google.common.base.Predicate; If you use completion assist in Eclipse -- Control-Spacebar -- study the list of offered completions. Don't just pick the first one. Look to the right where it will identify the source of the completion in light grey text. If you are looking at the thirdparty.guava one, move to the next one until you see the google.common one.
Maybe someone can give some insight into what the thirdparty.guava library is used for, whether it needs to be in the build path, and in what order Guava libraries ought to appear in the typical GWT project.
Guava classes that are GWT compatible are (supposed to be) marked with the @GwtCompatible annotation. Check the source.
According to this, it is: http://guava-libraries.googlecode.com/svn/trunk/javadoc/com/google/common/base/Predicate.html
You'll still need to follow Thomas Broyer's instructions to put the correct into the .gwt.xml file.
