Geb-Spock using wrong Groovy version

Question

When I try to create a functional test using:

grails create-functional-test acceptance.tests.Logout

I'm getting this error, because Spock tries to use a wrong Groovy version:

| Error Failed to compile GenerateAsyncController.groovy: startup failed: Could not instantiate global transform class org.spockframework.compiler.SpockTransform specified at jar:file:/Users/reinaldoluckman/.gradle/caches/modules-2/files-2.1/org.spockframework/spock-core/2.0-M2-groovy-3.0/396867de1bbbe11e85e197c22f0e6de07643185a/spock-core-2.0-M2-groovy-3.0.jar!/META-INF/services/org.codehaus.groovy.transform.ASTTransformation because of exception org.spockframework.util.IncompatibleGroovyVersionException: The Spock compiler plugin cannot execute because Spock 2.0.0-M2-groovy-3.0 is not compatible with Groovy 2.5.6.

But in my project only Groovy 3 is a library.

Here is my build.gradle:

Here is gradle.properties:

webdriverBinariesVersion=1.4
chromeDriverVersion=86.0.4240.22
geckodriverVersion=0.23.0
seleniumSafariDriverVersion=3.14.0

How can I make Spock (that is a transitive dependency from Geb) to use the Groovy 3 (that is already in my classpath)?

Thanks in advance.

Answer 1

A quick check shows that the current master of Geb still depends on spock-1.3-groovy-2.5, so I am not sure if you can use Geb with Spock 2.0. But it looks as if you cannot, see Geb issue #619 . Consequently, you want to stick with Spock 1.3 and Groovy 2.5 for now.

Answer 2

With Grails 4.1.0.M2, grails create-functional-test acceptance.tests.Logout worked as a charm. But I did some extra steps (to avoid bleeding edge, as @kriegaex says in comments).

What I did was:

1. Updated to Grails 4.1.0.M2
2. Rolled back to Gradle 5.1.1 (recommended version)
3. Recreated gradle wrapper ( gradle wrapper --gradle-version 5.1.1 )
4. Continued with Groovy 3.0.6 (3.0.3 gave a dependency incompatibility)
5. Everything else came from Maven BOM associated with Grails 4.1.0.M2 (as saw in my build.gradle in my question )

But the gotcha is that Grails 4.1.0.M2 comes with Spock 2.0-M2-groovy-3.0, that solves the problem pointed out in @kriegaex answer .

Also, thanks for @JeffScottBrow for the tips in the comments.
