Do not attempt to serialize project.version in task of type Test

[ysb33r]

This line is incorrect

grails-gradle-plugin/src/main/groovy/org/grails/gradle/plugin/core/GrailsGradlePlugin.groovy

Line 407 in 45285f7

task.systemProperty Metadata.APPLICATION_VERSION, project.version

You do the correct thing when creating the properties in buildProperties task.

Line 407 should also have the same conditional.

NOTE: This bug breaks buildscripts that apply Grails plugins and a pluging that use Grolifant 2.x.

The only workaround in such situations is to add

gradle.taskGraph.whenReady {
    project.tasks.withType(Test).configureEach {
        it.systemProperties['info.app.version'] = project.version.toString()
    }
}

or

gradle.taskGraph.whenReady {
    project.tasks.withType(Test).configureEach {
        it.systemProperties['info.app.version'] = grolifant.versionProvider.get()
    }
}
