compileScoverageScala waif with "bad option: -P:scoverage:sourceRoot:C:\"

[rafalmag]

Thanks for releasing v8.0.0 that supports scala 2.13.9+ (as previous Scala versions were affected by CVE-2022-36944 ).
However on Windows there is an issue that the report cannot be generated from Gradle plugin.

The error is:

> Task :compileScoverageScala FAILED
[Error] : bad option: -P:scoverage:dataDir:C:\Users\Rafal\Documents\IdeaProjects\gradle-scoverage\build\resources\functionalTest\projects\scala-single-module\build\scoverage
[Error] : bad option: -P:scoverage:sourceRoot:C:\Users\Rafal\Documents\IdeaProjects\gradle-scoverage\build\resources\functionalTest\projects\scala-single-module
two errors found

FAILURE: Build failed with an exception.

Steps to reproduce:
Run test for org.scoverage.ScalaSingleModuleTest#checkScoverage on Windows, example by running command gradlew :functionalTest --tests "org.scoverage.ScalaSingleModuleTest.checkScoverage".

The very same test on tag 7.0.0 or 6.1.0 does not complain about "bad option", but fails with:

Execution failed for task ':checkScoverage'.
> Only 0% of project is covered by tests instead of 30% (coverageType: Line)

I guess that test is anyway not 100% compatible with Windows, but it would be already a progress if the test from tag v8.0.0 would at least produce "0% coverage" instead of failing with bad option.

Exception from org.scoverage.ScalaSingleModuleTest#checkScoverage (when added extra parameter "--stacktrace"):

* Exception is:

https://github.com/scoverage/gradle-scoverage/blob/master/src/main/groovy/org/scoverage/ScoveragePlugin.groovy#L204 has

scalaCompileOptions.additionalParameters.add('-Xplugin:' + pluginFiles.join(":"))

I suspect this does not work with a path like c:\ - @msigmond, is this join required please?

--edit
I think scoverage/sbt-scoverage@8ba258c has the answer.

@rafalmag, could you test the replacement of ":" with File.pathSeparator on Windows please?

[rafalmag]

Great, main issue fixed! Thanks, I was experimenting with dataDir and sourceRoot and could not find why zinc is complaining. Once fixed Xplugin then I see scoverage plugin logs from "Zinc".

Now the test: org.scoverage.ScalaSingleModuleTest#reportScoverageWithExcludedClasses is green (and before the fix it also failed).

Regarding the org.scoverage.ScalaSingleModuleTest#checkScoverageFails - the test is still red (like on 7.0.0 or 6.1.0 branches) with:

So no longer "bad option" error, but it seems it cannot read the coverage from reports. I checked the files:

2023-05-20T16:24:16.560+0200 [INFO] [org.gradle.api.Project] [scoverage] Written Cobertura XML report to C:\Users\Rafal\Documents\IdeaProjects\gradle-scoverage\build\resources\functionalTest\projects\scala-single-module\build\reports\scoverage\cobertura.xml

and the test coverage is 50%, so I guess there might be still some minor, but similar bug in checkScoverage or scoverage compiler plugin.

PS: The join seems to be required, as there are 3 files on the "-Xplugin" parameter list:

What is your Locale please? I wonder if there is a difference between the expected number format and the actual number format.

--edit I have deployed 8.0.1 with the compilation fix

[rafalmag]

Thanks for prompt deployment.
Indeed problem is locale related. My locale is "pl_PL" (decimal separator = ','). When I run the test with JVM parameters: " -Duser.country=US -Duser.language=en" (decimal separator = '.' ) test is green now. Even all tests are green now :)

BTW: Both cobertura.xml and scoverage.xml (with pl_PL or en_US locale) are using "." as decimal separator (as per XML standard), so I guess that checkScoverage should parse those values using non-locale oriented parser.

I think the issue is in org.scoverage.CoverageChecker#checkLineCoverage(java.io.File, org.scoverage.CoverageType, double) that uses NumberFormat from default locale.
If you would agree - I can prepare a PR with NumberFormat hardcoded like in DecimalFormat. Then org.scoverage.CoverageCheckerTest#failsWhenStatementRateIsBelowTarget tests fails with an error:

Expected: expects message "Only 33.33% of project is covered by tests instead of 100% (coverageType: Statement)"
     but: was <org.gradle.api.GradleException: Only 33,33% of project is covered by tests instead of 100% (coverageType: Statement)>

but it always looks stange to see an English text with "," used in numbers - so I would propose to remove number formats localization from error messages as well.

Published 8.0.2 with support for Windows and non-US locale
