The file cobertura-instrument is probably not available on your path. In windows you have to put the directory where Cobertura is installed in the list at the PATH entry. Right click my computer, properties, advanced, enviroment variables and add the cobertura directory at the variable PATH at the user section (when there is no PATH, create it)

cobertura-instrument target\classes\.

cobertura-report â€“format html â€“destination c:\temp\cobertura â€“source src\main\java

Can anybody please, help me out with this?
These commands are not working for me.result of execution goes like:
‘cobertura-report’ is not recognized as an internal or external command,
operable program or batch file.

‘cobertura-instrument’ is not recognized as an internal or external command,
operable program or batch file.

Hi Jeroen,
That plugin supports cobertura 1.7.
I want a plugin which supports cobertura 1.8.
Thanks,
Sachi

The plugin is located on the Ibiblio repository:

Hi Piyush,
I am trying to locate the cobertura-maven-plugin for maven 2 and cobertura 1.8.
Where did you get that plugin?
Thanks,
Sachi

Hi All,
I’m using Maven 2.0.4 and Coubertura 1.8. I’ve no issues producing reports when executing the steps as mentioned in the conclusion. But When I use Maven and do mvn cobertura:cobertura, I get a Null Pointer Exception. There is no problem in instrumenting the classes thou’.
For your reference I’m providing the stack trace.

[ERROR] Exception in thread “main” java.lang.NullPointerException

Can anyone please guide me as to what I’m missing.

Thanks in advance,
Piyush

I think there’s no plugin for Eclipse, but there is for JClover and both applications are quite similar, so it shouldn’t be too difficult to convert the JClover plugin I guess.

What exactly do you mean with create your own instrument classes? Instrumenting a class is nothing more than some byte code manipulation of compiled classes.
