[FIXED] Why does jacoco:check give an error when I create a test class

Issue

I am using IntelliJ and when I run my project it works fine with jacoco and all dependencies.

When I create a test class I suddenly get an error and I don't understand why.

The error I get is this one.

[ERROR] Failed to execute goal org.jacoco:jacoco-maven-plugin:0.8.5:check (jacoco-check) on project 
statistik-jar: Coverage checks have not been met. See log for details. -> [Help 1]

[ERROR] After correcting the problems, you can resume the build with the command

When I have one test class, it works fine, but it gives this error when I add one more. The folder looks like this when I get the error:

/Test
   /test.class  <-- working
   /folder
      /test2.class <-- gives a error

This error occurs when creating a second class

Solution

Because Jacoco works with percentile if you create more classes and do not have relative tests it will give the error.

                        <value>COVEREDRATIO</value>
                        <minimum>0.xx</minimum>

Check these data. I will give you some insight.
