Brian Deacon Brian Deacon 8, 12 32 Perhaps try: Dave Jarvis 21k 30 You also need to change xmlns from: And don't forget to 'validate' the offending file after making the change. I use Maven extensively and do not get this error on Maven files unless they are located in the target directory. In that case it is better to add a rule to disable validation in the target directory than it is to ignore the error. This doesn't fix the problem, just hide the symptom. If you only use Eclipse to build Android applications, then this "solution" is acceptable.
eclipse - No grammar constraints (DTD or XML schema) detected for the document - CODE Q&A Solved
So be careful. We have to deal with badly formed 3rd party files all the time, especially xml files, Yes it would be nice if they fixed them, but they don't, so I just need to switch off pointless warnings, so that I can see the important , real warnings. This fix really helped me, Thanks. Clear the cache for stored validation files. Tiris Tiris 1 This worked for me.
Looks like at some point my Eclipse cached a bogus copy of java. This worked for me too with when my Spring bean files started throwing this error. You pick the URL specified for the schema, for a declaration like xsi: You can now redirect the location of the file with the workspace catalog in Eclipse: The problem is two-fold: Eclipse ships with a cache of a lot of well-known XSD's.
Unfortunately it appears that after Oracle revised java. Basically, just write your xml to conform to required rule.

- No grammar constraints (DTD or XML schema) detected for the document.
I have this dtd: The xml is:. The content of element type "template" must match " description,variation? This worked for me in Eclipse 3. Then in the Validating files section of the preferences panel on the right, choose Ignore in the drop down box for the "No grammar specified" preference. You may need to close the file and then reopen it to make the warning go away. I know this question is old but it was the first one I found when searching on the warning, so I'm posting the answer here for other searchers.
Android:No grammar constraints (DTD or XML schema) detected for the document
Comments on each piece of your DTD below. Refer to official spec for more info. DTDs serve to establish agreed upon data formats and validate the receipt of such data. They define the structure of an XML document, including:. Meaning of above lines As key: For me it was a Problem with character encoding and unix filemode running eclipse on Windows:. Just marked the complete code, cutted and pasted it back in short: I can't really say why you get the "No grammar constraints When I put the declaration back and validate again, I get this error message:.
Solved this issue in Eclipse 3. Two completely identical layouts of which one had the warning. Closed down all tabs and when reopening the warning had disappeared. I used a relative path in the xsi: What I found to be the solution was something very very simple that I think you should try before tinkering with the preferences. In my case I had this problem in a strings file that had as a base tag "resources" The problem has since disappeared and never gave me any warnings.
It may sound to simple to be true but hey, sometimes it's the simplest things that solve the problems. I too had the same problem in eclipse using web. Thank you for your interest in this question.

Would you like to answer one of these unanswered questions instead? The xml is: I changed the xml, I am getting this error now: Is this in Eclipse? John - Yeah this is eclipse. Check these links: If you only use Eclipse to build Android applications, then this "solution" is acceptable. So be careful. I find eclipse far faster and less crash-prone if I keep one install for working on android apps and another one for doing java web development work. So I'd be happy to use the solution above just for my android ADT install of eclipse.
Pablo Bianchi 2 Sabuj Hassan Sabuj Hassan This is the correct answer in my opinion. It's better than to advise everybody coming here to just set the warning to ignore This should be the accepted answer. Marc Bernstein Marc Bernstein I had to make sure that the "manual" box as well as the "build" box was checked and then do a manual validate by right-clicking on the project and selecting "Validate" for the warnings to go away.
It seems that there is a bug in eclipse in which the validator gets messed up.
You should be able to at least have the manual validation work even if you don't want it to happen at build time. And then you should be able to easily clear the warnings after doing the manual validation. Until then this is the solution. The warning breaks intellisense and I spent quite a lot of time figuring what reason was.
This resolved it:
