I have a maven project with jacoco plugin, which generates reports in different formats, such as html, csv and xml. But I need only html. How can I specify it?

Here is some code, where I add jacoco plugin:

I am trying to establish a process of collecting QA tests coverage and aggregating this information into a single report. We have a big team and code changes very frequently, so my main problem was related to impossibility to collect coverage from the single app version. According to the documentation Jococo should warn about all classes where execution data does not match and report them as not covered.

I am new to Maven and am struggling to find the right way to ask this question (since I doubt the problem is specific to DynamoDBLocal).

I am attempting to start a REST server using Jersey with Grizzly servlet, but mvn exec:java is failing because I can't figure out how to specify mainClass. For my unit tests, I'm using in-memory DynamoDBLocal to mock the database. I am also hoping in the short term to use DynamoDBLocal as the actual database while running the REST server (just during proof-of-concept stages) just to not spend money on AWS until I'm ready to serve some traffic.

When running mvn exec:java, I get the following failure:

I have a projet composed of numerous modules. I am running both JaCoCo for unit tests coverage and Sonar for code quality.

For a technical reason, I can't use JaCoCo reports for one of my modules (GWT erases the target folder and I couldn't go past this issue yet).

Let's say I have 8 modules, from 1 to 8. One of them is for domain objects only, so I don't want to cover it with my tests. Same goes for another one, dedicated for auto-generated classes.

JaCoCo runs on 5 modules, and Sonar on 6 modules.

The total instructions shown by JaCoCo is 145k.

Sonar shows a total of 75k LOC.

Aren't they quite the same ? Did I miss something ? Is JaCoCo taking in account the whole project whatever reports I feed him ? What can possibly explain this gap in measurement ?

According to this post on StackOverflow and EclEmma's documentation, exclusion of classes from the coverage should be very possible. However, while the "includes" field works just as described, the "excludes" field does not.

Take the following project hierarchy and coverage runtime settings respectively:

But, after running the coverage operation, the exclude setting does not work:

As one can see, the excluded package is still being included in the overall coverage testing. In addition, if you mark '*' in "includes" and mark a package in the "excludes," it is still not excluded.

According to this issue and Godlin's answer:

Unfortunately currently EclEmma does not support exclusions from the report as stated in [issue]

However, this problem is well over a year old. I am asking if I am doing something incorrect or if this problem is still ongoing? What is the point of including these two fields if they don't work as intended?

Version(s):

Eclipse: Oxygen Release (4.7.0)

I have to generate coverage report for simple java application(No maven/ant) by using jacoco. To do this, downloaded jar files for jacoco and put it in library folder. I want to use jacococli.jar for report generation, but before that need to figure out how to generate jacoco.exec data.

So far I have tried this,

Used following command to generate Jacoco.exec (by following jacoco doc)

http://www.eclemma.org/jacoco/trunk/doc/prepare-agent-mojo.html

I am like really not familiar with maven at all. And the project that I am working on requires it....

I am trying to customize this Jacoco tool in maven. Especially the "include" parameter for prepare-agent goal. I am testing a big project with about 4000 classes in many different packages. But the only coverage information that I need is only from 5-10 classes.

Any idea how I can specify something like this? Basically specify "include" while running test. Or do I have to specify it in the POM file?

"mvn jacoco:prepare-agent -Dinclude = "weka.associations.Apriori" test"

I want to get a code coverage report (or tracking controller flow of an application) when I execute the some scenario on live application i.e. while application running in server, so I have refereed the official Jacoco documentation and did as fallows

As a first step, I tried to bind the jacoco agent to the application running port

You can run JUnit tests with the Jacoco agent to produce wonderful coverage reports. (It produces an opaque *.exec file during the running of the unit tests).

Some tools such as Sonar - read the *.exec file and gather data to produce reports. Sonar is able to tell Unit test duration - but I'm not sure if it gets it from this *.exec file.

My question is: Does Jacoco record unit test duration? (Regardless of whether it shows it in its generated report).
