How to resolve scoverage-maven-plugin:1.1.0-SNAPSHOT Skipping SCoverage report generation

[abdheshkumar]

Hi
I am trying to integrate scoverage with maven but am getting SCoverage report generation info in logger

These are the steps that i followed :

1. Integrate configuration in xml file
   pom.xml

<plugin>
                <groupId>org.scoverage</groupId>
                <artifactId>scoverage-maven-plugin</artifactId>
                <version>${scoverage.plugin.version}</version>
                <executions>
                    <execution>
                        <id>coverage</id>
                        <phase>test</phase>
                        <goals>
                            <goal>report</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <excludedFiles>.*Object</excludedFiles>
                </configuration>
            </plugin>

1. run mvn scoverage:report

I don't know this configuration is right or not. Please guide me how can i make this working.

Thanks

Does it work with version 1.0.4?

[abdheshkumar]

No it doesn't work with 1.0.4 too?
Maybe i configured in wrong way. The configuration that i posted is correct? and the commend that i run is correct?

[gslowikowski]

It should work with 1.0.4.
Does not work with 1.1.0-SNAPSHOT, I found a bug introduced recently. Anyway, it does not print Skipping SCoverage report generation for me. Can you attach (or send me directly, if you cannot publish it) Maven execution log with debug info ( -X option)?

Above is project pom.xml file configuration, please check that all is right configuration?
Now i am not getting Skipping SCoverage report generation error when i run mvn scoverage:report but it throwing exception [ERROR] Failed to execute goal net.alchim31.maven:scala-maven-plugin:3.1.3:compile (scala-compile-first) on project scala-scoverage-demo: Execution scala-compile-first of goal net.alchim31.maven:scala-maven-plugin:3.1.3:compile failed. NullPointerException -> [Help 1]  

When i run mvn compile it compile all files successfully. I don't know what the happening...:-(

[gslowikowski]

I need execution log.

[gslowikowski]

Hi
1.1.0 version was released yesterday. Try it, please.
Without sample project or your execution log I cannot reproduce the issue and will close this issue.

[abdheshkumar]

Hi @gslowikowski
I am getting same issue like this scoverage/scalac-scoverage-plugin#93
and i am running on scala 2.10.

[gslowikowski]

So something has changed, you had no exception before. Anyway this is not a Maven plugin issue. I still cannot help you without sample project. Tried to build your project https://github.com/abdheshkumar/sbt-poc-coverage, but it works for me.

[abdheshkumar]

Yes @gslowikowski it's working fine with Scala 2.11+ but its not working 2.10 at least for me.

[gslowikowski]

Ok, I'm closing, this is not Maven plugin issue.

[ryan-williams]

Just a quick drive-by to note that I was just seeing the

[INFO] Skipping SCoverage report generation

message and eventually realized it was because my POM had <packaging>pom</packaging> instead of <packaging>jar</packaging> due to a copy/paste error on my end.

[abdheshkumar]

So now it would work with Scala 2.10?

[abdheshkumar]

Still same issue:

@abdheshkumar
From your logs:

[WARNING] Skipping SCoverage execution - unsupported Scala version "2.10"

BTW, I cannot compile your test project with Scala 2.10.x. There is compilation error.

@abdheshkumar were you able to resolve this issue?
