Re: GWT 2.8.0 RC1 - InternalCompilerException: Error constructing Java AST

Try adding just the following dependency:

<dependency>
    <groupId>xml-apis</groupId>
    <artifactId>xml-apis</artifactId>
    <version>1.4.01</version>
</dependency>

Also this, if you have not already done so:

<dependency>
   <groupId>javax.servlet</groupId>
   <artifactId>javax.servlet-api</artifactId>
   <version>3.1.0</version>
   <scope>provided</scope>
</dependency>

And this is how GWT dependencies look for me (2.8.0-rc1):

<dependencyManagement>
   <dependencies>
      <dependency>
         <groupId>com.google.gwt</groupId>
         <artifactId>gwt</artifactId>
         <version>${gwtVersion}</version>
         <type>pom</type>
         <scope>import</scope>
      </dependency>
   </dependencies>
</dependencyManagement>

<dependencies>
   <dependency>
      <groupId>com.google.gwt</groupId>
      <artifactId>gwt-servlet</artifactId>
      <scope>runtime</scope>
   </dependency>
   <dependency>
      <groupId>com.google.gwt</groupId>
      <artifactId>gwt-user</artifactId>
      <scope>provided</scope>
   </dependency>
   <dependency>
      <groupId>com.google.gwt</groupId>
      <artifactId>gwt-dev</artifactId>
      <scope>provided</scope>
   </dependency>

<dependencies>

I get the same issue using the maven plugin 2.8.0-rc1... Anyone got the maven gwt plugin working? Or is it because I have some rogue dependency?
