Tests in Groovy don't run if a plugin is added as a dependency #760
Description
When adding org.asciidoctor.jvm.gradle.plugin as a dependency to another Gradle plugin project, Groovy tests fail with a GroovyRuntimeException due to conflicting Groovy module versions.
Error message:
GroovyRuntimeException: Conflicting module versions. Module [groovy-nio is loaded in version 3.0.17 and you are trying to load version 4.0.28
groovy-nio:4.0.28 is embedded in Gradle 9.1.0, but the plugin drags in groovy-nio:3.0.17
Steps to reproduce:
- Create a plugin project with the following build.gradle.kts
plugins {
id("groovy")
id("java-gradle-plugin")
}
group = "example"
version = "1.0-SNAPSHOT"
repositories {
mavenCentral()
gradlePluginPortal()
}
dependencies {
implementation("org.asciidoctor.jvm:org.asciidoctor.jvm.gradle.plugin:5.0.0-alpha.1")
testImplementation(platform("org.junit:junit-bom:5.10.0"))
testImplementation("org.junit.jupiter:junit-jupiter")
testRuntimeOnly("org.junit.platform:junit-platform-launcher")
}
tasks.test {
useJUnitPlatform()
}
gradlePlugin {
plugins {
create("documentation") {
id = "example.documentation"
implementationClass = "example.DocumentationPlugin"
}
}
}
- Add any simple Groovy test, e.g. ExampleTest.groovy.
- Run ./gradlew test

Workaround:
Exclude groovy-nio from the plugin dependency:
implementation("org.asciidoctor.jvm:org.asciidoctor.jvm.gradle.plugin:5.0.0-alpha.1") {
exclude("org.codehaus.groovy", "groovy-nio")
}
