Hello, I am currently using GWT2.6.0. I am trying to migrate to 2.7 but things do not work well.
-- There is no eclipse version for GWT2.7, neither any instructions, so I downloaded the SDK and added it to my project setting.
I also changed module.xml file.
from:
<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 2.6.0//EN"
"http://google-web-toolkit.googlecode.com/svn/tags/2.6.0/distro-source/core/src/gwt-module.dtd">
to:
<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 2.7.0//EN"
"http://gwtproject.org/doctype/2.7.0/gwt-module.dtd">
But it is unable to compile, and constantly Eclipse complains there is unknown error, or nullPointerException...
I get the following errors during compilation:
[ERROR] An internal compiler exception occurred
com.google.gwt.dev.jjs.InternalCompilerException: Unexpected error during visit.
