JaCoCo report fails in Jenkins: java.lang.ArrayIndexOutOfBoundsException

Question

I have been using JaCoCo locally with no problem.

When running a Jenkins job on a remote server, the job builds fine and generates JaCoCo coverage report (i.e. it appears in my workspace/report folder) but the build fails when attempting to publish the report on Jenkins.

I am using Jenkins 1.460 and JaCoCo 5.0.0.

I have configured Jenkins with:

• Path to exec files: **/**.exec
• Path to classes: **/dist/validation/WEB-INF/classes
• Path to source: **/src (I have also tried **/Validation/src, and explicitly including **/**.class and excluding other file types)

Is this a configuration problem, or a compatibility error?

[EDIT: In case it helps anyone else, other forums say JaCoCo requires ASM 5.+ to manage Java 8 class analysis. I am already using ASM 5.0.1.]

[UPDATE - solution]

Using this answer I installed the recently released JaCoCo-0.7.4 (see eclemma.org/jacoco) on my local drive. This version contains the fix for issue 27088. I also had to delete and then reinstall the Jenkins JaCoCo plugin (I used the Jenkins Plugin Manager).

Answer 1

There appears to be a compatibility problem between the JaCoCo version used during build and the version used by Jenkins in the post-build action.

The maven-jacoco-plugin version 0.7.3.201502191951 in combination with the Jenkins JaCoCo Plugin version 1.0.18 causes this problem. Version 0.7.2.201409121644 of the maven-jacoco-plugin appears to be compatible.
