I can run the Java version of my project fine by simply importing Guava libraries like so:

```
import com.google.gwt.thirdparty.guava.common.collect.ImmutableList;

```

Following the advice [here](http://groups.google.com/group/playn/msg/cccb7916d5c2d40c), I've added this line to html/pom.xml:

```
<dependency>
  <groupId>com.google.guava</groupId>
  <artifactId>guava-gwt</artifactId>
  <version>10.0.1</version>
</dependency>

```

And this line to html/project.gwt.xml file:

```
<inherits name="com.google.common.collect.Collect"/>

```

But when I try to GWT-Compile my HTML version in Eclipse, I get errors like the following:

```
[ERROR] Line 61: No source code is available for type com.google.gwt.thirdparty.guava.common.collect.ImmutableList<E>; did you forget to inherit a required module?

```
