NPE in MethodAnalyzer.java:287

[mhankus]

Jacoco is run from jenkins job, and fails with NPE in MethodAnalyzer.java:287.
I'm using 0.7.1.201405082137

@mhankus Thanks for reporting this. Any chance that we can get the "PATH_TO_SOME_FILE.class" for further analysis? If you can't share this here please sent it to my last name at mountainminds.com.

@mhankus Thx for providing the class file. Unfortunately I cannot reproduce the problem. Can you please double check that you provided the exact same class file directly from the build process where the problem occurs (target/classes)?

[bill-lin]

We got exactly the same error after upgrade jenkins jacoco plugin to 1.0.14. I will email you a sample class t

@mhankus @bill-lin Thanks for providing sample classes! Unfortunately I cannot reproduce this issue. My guess is that this is a Jenkins specific problem (e.g. wrong ASM version).

Are you able to create a regular JaCoCo coverage report without Jenkins?

[Godin]

@mhankus @bill-lin @marchof indeed - seems that there is mess in ASM dependencies in Jenkins plugin: https://github.com/jenkinsci/jacoco-plugin/blob/master/pom.xml#L97 At least because it depends on 4.x , whereas JaCoCo 0.7.1 uses 5.x. I can open PR or even push changes directly into Jenkins plugin, but unfortunately don't have time to test it properly.

@Godin Thanks for the analysis! I tried to run JaCoCo 0.7.1 with ASM 4.x and got the following error:

https://issues.jenkins-ci.org/browse/JENKINS-23426

Anyways I close this issue here for JaCoCo.

@mhankus @bill-lin Can you please report the problem to the Jenkins plug-in maintainer? https://wiki.jenkins-ci.org/display/JENKINS/JaCoCo+Plugin
