Problems with outputting merged reports and updating JaCoCo version

KChernenko opened this issue 6 years ago · 19 comments

Hi! First of all thanks for the plugin - I've found that it's the only one that actually works for me.
However, I faced with several problems (because of a multi-module project) which I can't solve.

Task jacocoTestReportMerged (after executing ./gradlew clean jacocoTestReport mergeJacocoReports jacocoTestReportMerged) fails with the following stacktrace:

Caused by: java.lang.IllegalStateException: Can't add different class with same name: com/gen/bettermeditation/utils/preferences/NameOfTheClass
        at org.jacoco.core.analysis.CoverageBuilder.visitCoverage(CoverageBuilder.java:106)
        at org.jacoco.core.analysis.Analyzer$1.visitEnd(Analyzer.java:92)
        at org.objectweb.asm.ClassVisitor.visitEnd(ClassVisitor.java:317)
        at org.jacoco.core.internal.flow.ClassProbesAdapter.visitEnd(ClassProbesAdapter.java:133)
        at org.objectweb.asm.ClassReader.accept(ClassReader.java:697)
        at org.objectweb.asm.ClassReader.accept(ClassReader.java:506)
        at org.jacoco.core.analysis.Analyzer.analyzeClass(Analyzer.java:107)
        at org.jacoco.core.analysis.Analyzer.analyzeClass(Analyzer.java:142)

If I exclude NameOfTheClass.class through the excludes in the module config, I'll get another fail with another class and so on. This happens only with jacocoTestReportMerged task but not with mergeJacocoReports.

I want to use a newer version of the JaCoCo, because it possibly works better with Kotlin (related items: this and this). However, if I override configs in each module with, for example, version 0.8.1 my build (./gradlew clean jacocoTestReport mergeJacocoReports) will fail with the following stacktrace:

Caused by: java.io.IOException: Incompatible version 1007.

Am I doing something wrong?

Answer 1 · 2018-07-16T12:53:29.000Z

Can you change ./gradlew clean jacocoTestReport mergeJacocoReports jacocoTestReportMerged to ./gradlew jacocoTestReportMerged and see whether that fixes your issue?

The second case is interesting. Which Gradle version are you using?

Answer 2 · 2018-07-16T13:02:27.000Z

Unfortunately ./gradlew jacocoTestReportMerged does not fixed the issue - I'm still getting Caused by: java.lang.IllegalStateException: Can't add different class with same name
Gradle wrapper version is 4.8.1 and the plugin version is 3.1.3

Answer 3 · 2018-07-16T13:05:24.000Z

Is NameOfTheClass duplicated? Otherwise why is it complaining?

I've not tried JaCoCo 0.8.1 myself. But the exception is coming from JaCoCo so something must be wrong

Answer 4 · 2018-07-16T13:49:46.000Z

Nope. It could be even an Application class. Maybe it somehow connected with Kotlin? I have a companion object in the Application class or the case when we can place an interface and it's implementation in the same file (NameOfTheClass.kt: NameOfTheClass interface and NameOfTheClassImpl class). The stacktrace was pointing to such classes.

Answer 5 · 2018-07-16T14:10:02.000Z

Could be. Do you have any repo where I can toy around with it? Otherwise it's hard for me to take any actions.

Answer 6 · 2018-07-16T16:48:27.000Z

I've made a sample repo: https://github.com/KChernenko/MyTestCoverageApp
Thanks!

Answer 7 · 2018-07-17T15:33:02.000Z

404 not found :/

Answer 8 · 2018-07-17T16:50:30.000Z

Sorry, my bad - forgot to make it public.

Answer 9 · 2018-07-18T10:18:11.000Z

Seems super weird since you essentially don't have any tests at all.

./gradlew jacocoTestReport succeeds

Merging likely fails since there's nothing to merge.

Answer 10 · 2018-07-18T14:20:18.000Z

I've added several simple tests and merge task is still failing :(

Answer 11 · 2018-07-18T14:29:04.000Z

./gradlew mergeJacocoReports seems to work in my case. Dunno what's wrong with jacocoTestReportMerged

Answer 12 · 2018-09-11T01:41:23.000Z

I've also bumped into this issue (or at least a similar one) when setting JaCoCo version to 0.8.x for better Kotlin support.

Tried mergeJacocoReports, jacocoTestReportMerged pretty much anything I could come up with. Nothing seems to work, everything fails with the same exception:

AS 3.2-rc3, Gradle wrapper 4.10.

I'll gladly provide more info if needed.

Answer 13 · 2018-09-11T01:55:44.000Z

We have the same issue. I couldn't figure out a solution for this, yet.

Answer 14 · 2018-09-11T08:38:13.000Z

I'm not using JaCoCo 0.8+ yet. Is there something that Gradle needs to do? This plugin only forwards to those tasks / API provided by Gradle.

Answer 15 · 2018-09-11T14:41:31.000Z

I don't know. Glancing over Gradle docs I see that Gradle by default already uses JaCoCo 0.8.x. The stacktrace is not really helpful either...

Answer 16 · 2018-09-11T14:58:34.000Z

Yup but we override that one https://github.com/vanniktech/gradle-android-junit-jacoco-plugin/blob/master/src/main/groovy/com/vanniktech/android/junit/jacoco/GenerationPlugin.groovy#L62 with our default which is pre 0.8.x

Hi! I am getting this issue when using latest version (0.13.0).
Caused by: java.lang.IllegalStateException: Can't add different class with same name: com/datepickerexample/MainApplication$1
Is there anything I can try?

Nevermind: Added some files to excluded and got it to pass

I had a similar issue when I was using 0.13.0. It was resolved after I use the latest 0.14.0-SNAPSHOT version.
