Any of those help It looks like you're picking up the non-instrumented classes.
Could be because the classpath in your junit task has the compiled classes (build/classes) ahead of the instrumented (build/instrumented). Maybe reverse these in that classpath?

wish helps you Please read this QuickStartGuide.
You have to provide the source code and create an html report, to view complete statistics.
code :
java -cp emma.jar emmarun -r html -jar the_jar -sp path_to_source
emma - no runtime coverage data found

This might help you You get this error when you use wrong command to generate the report. Most of the online tutorial is advocating the wrong(may by old) command, even I got this error when I used below command to generate the report:
code :
{JAVA_HOME}\jre\lib\ext>java -cp emma.jar emma report -r html -in coverage.em, {ALFRESCO_HOME}\coverage.ec 
EMMA: processing input files ... 
EMMA: 1 file(s) read and merged in 60 ms 
EMMA: nothing to do: no runtime coverage data found in any of the data files
{JAVA_HOME}\jre\lib\ext>java -cp emma.jar emma report -r txt,html -in {JAVA_HOME}\jre\lib\ext\coverage.em -in C:\t1_tempSetup\Alfresco\coverage.ec 
EMMA: processing input files ... 
EMMA: 2 file(s) read and merged in 70 ms EMMA: writing [txt] report to [{JAVA_HOME}\jre\lib\ext\coverage.txt] ... 
EMMA: writing [html] report to [{JAVA_HOME}\jre\lib\ext\coverage\index.html]

wish helps you I have a strange scenario... while doing a EMMA coverage for UT, I get the total block coverage size more than line coverage size. , It's easy to get multiple blocks on the same line, for example:

Does that help This tool can help: https://github.com/jsargiot/visual-coverage
This tool converts the .coverage file to clover or to a html report.

around this issue Emma hasn't had a stable release since 2005, and doesn't play well with newer versions of the JDKs. Cobertura hasn't done any new development since 2011. Because of that, I no longer recommend to developers to use Emma or Cobertura.
I've switched to JaCoCo for code coverage. It was started by the Emma Eclipse team, and is actively being developed.
