Error running CoreTutorial

[marc...@gmail.com]

Hello,
I just recently found out about EclEmma, and I installed the plugin through Eclipse's Install Software mechanism using the update website. I am however having problem running the example. Just to let you know right away, I had trouble installing the ASM plugin... I kept getting errors using the update website, so I tried to download the plugin .jar.

I searched a bit through Google to find out how to install it, but I'm not sure if I did it correctly... I downloaded org.objectweb.asm_2.2.2, put it in my ...\eclipse_kepler\dropins folder, restarted my Eclipse with the -clean option. I was able to find the org.objectweb.asm_3.3.1.v201105211655.jar in my plugins folder, which I added to my classpath, the addition of which removed a compile error in the CoreTutorial file (the one that invokes Instrumenter).

When I try to run the example though, either normally or through Code Coverage,I get the following exceptions :

Exception in thread "main" java.lang.IncompatibleClassChangeError: class org.jacoco.core.internal.flow.ClassProbesVisitor has interface org.objectweb.asm.ClassVisitor as super class

I am using Kepler Service release 2 (x86)

Version: 4.3.2.v20140221-1852
Build id: M20140221-1700

OS : Windows 8.1 Enterprise, 64-bit

Thanks in advance for your help and I'll be ready to provide any other information that could help. Good day!

Ok, let's sort things out:

1) JaCoCo is a code coverage library which comes with integrations for
Ant and Maven.
2) The letest JaCoCo release 0.7.1 depends on ASM 5.0.1
3) EclEmma is the Eclipse integration of JaCoCo. It incudes all required
dependencies (in cluding ASM, excepts Eclipse of course)

Best regards,
