I have problem with build path in ant build file. due to bug in gwt. I created 1 gwt package(com.google.gwt.user.client.ui) into my project & copied MenuBar class, I modified the Menubar class code to solve our problem. its work great. even i can compile it from eclipse too.

But problem is that when i run ant build file. Menu Bar class taking from gwt jar & throws exception that "unresolved methods". I want to ant builds takes MenuBar class from my project package instead of gwt jar.

Please help me out what to do for that.

Below is the build.xml file content

Please some one help me...................... – kumar kasimala
Is your com.google.gwt.use.client.ui package inside your /src path? Can you copy&paste your ANT build.xml file? Can you copy&paste the stacktrace from the ANT build? That would help to find the problem ;) – Carlos Tasada
Yeah sure. I will update my question with ant build xml file. stracktrace from ant build is CloseAll() method is not found in the MenuBar. it is compiler exception just because I modified Menu bar class & added CloseAll Method for my purpose. Ant Builds take Menu bar class from GWT jar instead of my project src/gwtpackge/MenuBar – kumar kasimala
I don't know if you were able to solve this question (if so maybe you can answer your own question) but if you weren't able I can tell you that I saw two similar questions in SO regarding how to get ant to use your sources before an external jar. Can't find it now but just search for +ant +javac +jar – Ittai

You need to have your source earlier in the classpath than the GWT source so that your version of MenuBar is found first.

It looks like you're using both a classpathref attribute and nested classpath element in your GWT compilation task. The nested classpath appears redundant. I'm not saying that's necessarily the cause of your problem, but I would suggest that you spend some time tidying up the classpath declarations. I would guess that you'll fix the problem in the process. If not, it will at least be easier to see what's going on in your classpath.
