Cobertura 2.0.3 - unable to instrument

Question

I am using Corbetura-2.0.3 with java 1.7 and I am trying to instrument the classes in our build system via command line. Stuck at instrumenting classes. Please assist.

Here is the command:

./cobertura-instrument.sh 
   --basedir /ariba/9r2_sourcing/roots-S49r2/install/classes/ariba.app.approvable.zip 
   --destination /ariba/9r2_sourcing/Instrument 
   -auxClasspath /ariba/9r2_sourcing/roots-S49r2/install/classes

Wherein,

• /ariba/9r2_sourcing/roots-S49r2/install/classes/ariba.app.approvable.zip – zip containing classes which I would like to instrument
• /ariba/9r2_sourcing/Instrument – Folder to save instrumented classes
• /ariba/9r2_sourcing/roots-S49r2/install/classes – path where all other reference classes are present.

Output:

-bash-4.1$ ./cobertura-instrument.sh --basedir /ariba/9r2_sourcing/roots-S49r2/install/classes/ariba.app.approvable.zip --destination /ariba/9r2_sourcing/Instrument -auxClasspath /ariba/9r2_sourcing/roots-S49r2/install/classes

Also tried with:

• archivesdepth parameter as well; it gives the same above error.
• I have updated the cobertura-instrument.sh file with the right versions of jars present in Cobertura installed location.

Answer 1

I see , in command you have not mentioned classes which you need to instrument.

Example: Below command works.

sh cobertura-instrument.sh --basedir `pwd` GenerateReports.class My_lib.class

Note:
Classes need to be mentioned as complete filename (e.g. mycls.class)
-auxClasspath : Add any classes/jars that cobertura is unable to find during instrumentation i.e. classes to exclude from coverage
