Eclemma in eclipse showing different coverage than jacoco report from maven command line.

[prathy...@gmail.com]

Hello ,

in My eclipse i am using eclemma 3.1.0 version

in pom.xml i am using jacoco-maven-plugin 0.8.1 version.

When i run my test class in eclipse as Coverage As --> Test NG Test, Line coverage ,Branch coverage, total lines etc are showing different values compared to

JACOCO site report when run using maven install command in command prompt.

is there something i am missing? Please let me know if you need any thing.

Please help.

Hi,

JaCoCo works on debug information in Java class files. Eclipse has its own compiler which creates more detailed debug information in certain situations (e.g. multi-line expressions). But this should cause only a minor difference (and should not have an impact on line coverage).

Also note that we added a few filters to JaCoCo (for unwanted compiler artifacts). Depending on your Eclipse version you might use a older JaCoCo version in Eclipse.

For a detailed discussion please provide

1) An example snippet with its coverage values in both reports (Screenshots)

2) The version of the Maven plug-in.

3) The version of the EclEmma plug-in.

Regards,

marc
