Hello Marc,

              Thank for responding. Please find the attached error file. But same code is executing from eclipse

without any error using EclEmma V3.1.0. Junit tests are running similarly in both(ANT and eclipse)  Only facing issue with code coverage report. ANT(Jacoco) generated report is showing 0% for entire project. I tried with offline instrumenting too.

           

Thanks in Advance.

 

Regards,

Srinivas P.

Hi Srinivas,

the interesting part of the stack trace is here:

    [junit] Caused by: java.lang.ArrayIndexOutOfBoundsException: 287

    [junit] at org.jacoco.agent.rt.internal_b6258fc.asm.ClassReader.readUtf(ClassReader.java:3695)

    [junit] at org.jacoco.agent.rt.internal_b6258fc.asm.ClassReader.readUtf(ClassReader.java:3675)

    [junit] at org.jacoco.agent.rt.internal_b6258fc.asm.ClassReader.readUTF8(ClassReader.java:3656)

    [junit] at org.jacoco.agent.rt.internal_b6258fc.asm.ClassReader.readMethod(ClassReader.java:1388)

The ASM library cannot read the class file. This is most likely because the class file has a syntax error. This can be because the class file was compiled with an error (actually some javac versions created invalid class files) or there is another agent which modifies the class files in an invalid way.

Can you please provide the class file org/apache/logging/log4j/spi/AbstractLogger.class which is used in your build? To be sure you can add the classdumpdir option (https://www.jacoco.org/jacoco/trunk/doc/agent.html) so you will get the exact version of the class file which is seen by the JaCoCO agent.
