We are trying to upgrade from

google:gwt-user:2.0.0 --> org.gwtproject:gwt-user:2.11.0
google:gwt-servlet:2.0.0 -> org.gwtproject:gwt-servlet:2.11.0
extjs:gxt:2.1.0 -> com.sencha.gxt:gxt2.2.5-gwt2.X:2.7.0

This is blocking whole java upgrade any help is appreciacted
Is jsinterop-annotations on your project classpath? This was historically part of GWT itself, but version 2.8.1 RC1 split it out into its own jar, which you need to depend on separately.
GWT 2.0.0 to 2.11.0 is a huge jump, 15 years of changes, many release notes entries to review. Plus, you almost certainly will also need to update your GXT version as well, so keep an eye out for that.
I have added jsinterop-annotations-2.1.0.jar to the classpath but what is not too clear is what is giving errors like this java.lang.String cannot be resolved to a type. Also is there a recommended version for gxt which used should be used
The "String cannot be resolved to a type" means that there are still errors in the String.java file, like jsinterop-annotations being missing (since String uses jsinterop rather than JSNI now). Sharing the complete build log will help to track this down - but if you are still having jsinterop errors, you'll need to recheck how you changed the classpath.
I can't speak for what releases Sencha has that will work with recent GXT versions, you may need to do a little experimentation, post in their forums, or on the GWT mailing list. At a very quick glance, 2.3.1-gwt22 is the last GXT 2.x version that was made, but I believe there are two or so changes that have to be made to get it to compile with GWT versions past 2.4.0 or so. They appear to be both described in this thread:

Sencha has not supported the GXT 2.x series since 4.0.0 was released, about 8.5 years ago. Our company, Vertispan, can offer some paid support here if you have the appropriate GXT licenses and can't or don't want to post more details publicly that will help solve this.
No further details, closing - try the mailing list, stackoverflow (with the gwt tag), or join the live gitter chat if you still need help.
