Error while instrumenting class org.jacoco.examples.CoreTutorial$TestTarget

[sandee...@gmail.com]

Hi,

I am trying to run the CoreTutorial.java via Eclipse(Executed as a Java main program) and got "Error while instrumenting class org.jacoco.examples.CoreTutorial$TestTarget" exception.

I am using JDK 1.8, asm-4.1.jar, org.jacoco.core-0.6.4.201312101107.jar and org.jacoco.report-0.6.4.201312101107.jar.

Please guide if there is any other configuration is required.

Thanks.

Can you please provide the full stack trace?

Looks like you provide invalid input to the Analyzer. From the line
numbers you're probably running a modified version of the example
shipped with JaCoCo.

I tried to modified the version shipped with JaCoCo to check if I overcome previous error. Below is the stack trace I am getting with original version of JaCoCo.

Please find below full stack trace.

Ok, now I see the problem: If you use Java 8, you need at least JaCoCo
version 0.7.0 and ASM 5.0.

Hi Marc,

I have asm-5.0.jar, org.jacoco.core-0.7.0.201403182114.jar and org.jacoco.report-0.7.0.201403182114.jar in my classpath and still I am getting below stacktrace. I am using Java 1.8.0_60

Looks like your classpath is not complete. The class is question is
definitely part of ASM-all. Maybe you have just ASM-core on the path.

Thanks It worked. ASM-all made the difference.
