I am trying to get some reports with the code coverage information for my project. I found that scoverage-maven-plugin produce xml files covering the % of the different modules that the unit test cases have covered so far.
So I tried to add that plugin in my pom, but I am getting the following error:

Edits after @Dmytro feedback:
I added in the pom the following dependencies:
<dependency>
<groupId>org.scala-lang</groupId>
<artifactId>scala-compiler</artifactId>
<version>${scala.version}</version>
</dependency>
<dependency>
<groupId>org.scoverage</groupId>
<artifactId>scalac-scoverage-plugin_2.12</artifactId>
<version>1.4.1</version>
</dependency>
And changed the scope to
<scope.value>compile</scope.value>
But I am still getting the error: java.lang.NoSuchMethodError: 'scala.tools.nsc.reporters.Reporter scala.tools.nsc.Global.reporter()'
Could you try to add
<dependency>
<groupId>org.scala-lang</groupId>
<artifactId>scala-compiler</artifactId>
<!--<version>2.12.14</version>-->
<version>${scala.version}</version>
</dependency>
?

Does this change anything for you?
scoverage-maven-plugin 1.3.0 depends on scalac-scoverage-plugin 1.3.0
scalac-scoverage-plugin 1.3.0 depends on scala-compiler 2.12.0
https://github.com/scoverage/scalac-scoverage-plugin/blob/v1.3.0/build.sbt#L89
https://github.com/scoverage/scalac-scoverage-plugin/blob/v1.3.0/build.sbt#L15
scala-compiler is marked as provided in the dependencies of scalac-scoverage-plugin so should be added manually when needed.
The method scala.tools.nsc.Global.reporter() returns Reporter in scala-compiler 2.12.0 https://github.com/scala/scala/blob/v2.12.0/src/compiler/scala/tools/nsc/Global.scala#L1581 (it seems in 2.12.0 there is no scala.tools.nsc.Global.reporter(), it appears in 2.12.5). In 2.12.14 the signature is different, the method returns FilteringReporter https://github.com/scala/scala/blob/v2.12.14/src/compiler/scala/tools/nsc/Global.scala#L1748 https://github.com/scala/scala/blob/v2.12.14/src/compiler/scala/tools/nsc/Global.scala#L90 So the issue seems to be in the combination of versions scalac-scoverage-plugin 1.3.0 + scala-compiler 2.12.14.
Try to either upgrade scoverage-plugin or downgrade Scala version so that the signature of the method is the same (returning either Reporter both times or FilteringReporter both times). The signature changed in 2.12.12 -> 2.12.13 (Reporter -> FilteringReporter) https://github.com/scala/scala/blob/v2.12.12/src/compiler/scala/tools/nsc/Global.scala#L90 https://github.com/scala/scala/blob/v2.12.13/src/compiler/scala/tools/nsc/Global.scala#L90 If you're on scoverage-plugin 1.4.1 can you change Scala to 2.12.12?
Try then to downgrade the scala version:
<properties>
<scala.version>2.12.12</scala.version>
...
</properties>
in combination with
<dependency>
<groupId>org.scoverage</groupId>
<artifactId>scalac-scoverage-plugin_2.12</artifactId>
<version>1.4.1</version>
</dependency>
