Support for JDK 9 & 10

[winstonsimon]

Looks like gradle clover plugin has no support for JDK 9 and JDK10.

unexpected token: enum
[clover] ** Error(s) occurred and the instrumentation process can't continue.

classpath "com.bmuschko:gradle-clover-plugin:2.2.1"
apply plugin: "com.bmuschko.clover"
clover 'org.openclover:clover:4.2.1'

clover {
    targetPercentage = '100.000%'
    report {
        html = true
        testResultsDir = project.tasks.getByName('test').reports.junitXml.destination
        testResultsInclude = 'TEST-*.xml'
    }
    compiler {
        debug = true
    }
}

[clover] Processing files at 1.3 source level.

Please look into it.

thanks!

This is an issue with OpenClover version. Open an issue with the OpenClover project although I think this is already in their roadmap. Looks like it is coming in version 4.3.0

OpenClover support for Java 9

The plugin does not have control over this, we just provide the Gradle wrappers around the execution of the OpenClover Ant tasks behind the plugin tasks.

Thanks Alex for responding 👍

I tried using openclover 4.3.1 to get support for Java 10, but doing so I get the following error.

FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ':test'.

Thank you for the note @joferguson
I will try to take a look at the required changes for JDK 9 or later to support this.
I do not have much time right now to spend on this plugin but I will do my best.

This is still broken for my builds.

Why source level is 1.3 here? Can we set source level to 1.5 or higher?

[Alex-Vol-SV]

@qodjf the source level is controlled by your own Gradle source level settings. This plugin does not set the source level. The plugin is compiled at Java 8 level but will instrument up to the level supported by the OpenClover library.

@Alex-Vol-SV I'm seeing the same thing with regards to the version being set at 1.3 for source that is now at version 11.

I think the problem here is that if you use a higher source version than clover supports it drops it all the way down to 1.3 rather than falling back to the next highest supported version.

Is there a way to manually set the version the instrumentation is doing using this plugin? I would like to compile the project at 11 but I don't care if it winds up being compiled down to 8 for instrumentation purposes.

[Alex-Vol-SV]

I thought we were letting an override with default but we don't.
It could be added if that would help.

The code can be corrected in the plugin and the override exposed in the clover.compiler closure

[Alex-Vol-SV]

I am going to post 2.2.5 with the sourceCompatibility override to allow this to work as long as OpenClover can indeed process the source code at Java 9 level. I do not have any handy examples to prove it works in all cases but it does indeed override the setting so the Java compiler can be at Java 11 and OpenClover can be at 9 to work.
