When working with more than one .js file e.g. if I have a separate .js file that contains unit tests I start to see lots of warnings (I'm using the Eclipse plug-in) like the following where a .js file is referencing elements from another:

'<variable name>' is not defined

I can satisfy the warning and not break my code by including the following for any variables being used but are not within the physical .js file:

var myVariableReference = myVariableFromOtherFile || {};

The downside of course is that I have to keep repeating code such as the above in my unit tests files. For example as I am using a unit testing framework I would have to keep adding the inline variable 'references' for the functions that I'm using from the framework e.g:

var assertEquals = assertEquals || {}; 
var TestCase = TestCase || {};

Is there a way of configuring within eclipse so JsLint4Java scans the files as a whole? Or setting up 'Ignore' rules would be good so that I could avoid the repetitive variables as previously described.

Have you tried using the undef option? You may also try to use the predef tag to define any global variables that lint should except:

<target name = "lint">
    <echo message = "Running source files through JSLint..."></echo>
    <jslint options = "newcap,vars,browser">
        <formatter type = "plain" />
        <predef>app,$,other-variables-that-are-global-go-here</predef>
        <fileset dir = "${js}" includes = "**/*.js" />
    </jslint>
</target>
