ScoverageHtmlWriter fails with NoSuchMethodError

[PeterTCoyote]

Hi

The HTML output cannot be generated, because the plugin fails with an error.

Gradle: 5.3.1, Scala 2.11.x, plugin version 3.0.0

The HTML output has to be switched off.

    scoverage {
        coverageOutputHTML = false
    }

Otherwise, the gradle reportScoverage fails with the following error:

* Exception is:

Hi,

Yes, it seems this is the case. I can see a related change in the 3.0 update, but I need to look closer as a simple revert is not fixing my simple test case.

Stu.

[PeterTCoyote]

Thanks for looking into it.

[maiflai]

I was unable to reproduce it in an automated test case, but I've published 3.1.4 with the change reverted.

Please could you see if it addresses this issue?

Thanks
Stu

[PeterTCoyote]

Hi,

I've tried with the 3.1.4, but it fails with or without coverageOutputHTML = false.

plugins {
    id "org.scoverage" version "3.1.4"
}
subprojects {
...
    dependencies {
        scoverage 'org.scoverage:scalac-scoverage-plugin_2.11:1.3.1', 'org.scoverage:scalac-scoverage-runtime_2.11:1.3.1'
    }

    scoverage {
        scoverageScalaVersion = "2.11"
        coverageOutputHTML = false
    }
}

If I issue gradle reportScoverage or gradle build reportScoverage (even with clean build), I'm getting this:

* What went wrong:
Execution failed for task ':<module>:reportScoverage'.
> No signature of method: static scala.collection.JavaConverters.seqAsJavaList() is applicable for argument types: (scala.collection.mutable.ArrayBuffer) values: [ArrayBuffer(/.../build/reports/scoverageTest/scoverage.xml)]

I tried the 3.1.3, but it is failing with the above error.

openjdk version "1.8.0_212"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_212-b03)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.212-b03, mixed mode)

And scala 2.11.8 is used in the project.

With 3.0.0 it works okay (except the failure of the writer). Maybe there's some regression around the Scala version? Just guessing.

Kind regards,
Peter

Hi guys

I have one question. Why are you using different Scala versions for plugin-specific code. My Maven plugin uses Scala 2.12 (see https://github.com/scoverage/scoverage-maven-plugin/blob/master/pom.xml#L99) like SBT 1.x. The code for reports generation (https://github.com/scoverage/scoverage-maven-plugin/blob/master/pom.xml#L99) uses JavaConverters class.

Of course, proper version of scalac-scoverage-runtime dependency is added to the classpath, depending on Scala version used in the project.

[maiflai]

It is a good question.

Historically it was easier to just use the libraries that are already present, rather than defining a new set of dependencies. It looks like the changes in scoverage 1.4.0 / scala 2.13 will prevent this.

It would be easier if the scoverage plugin used Array instead of Seq.
