We have a Groovy project in which we develop some Gradle plugins. The dependencies section of its build file contains
dependencies
{
compile localGroovy()
// ...
}
After upgrading to Gradle 4.0, a cradle clean build ends prematurely with the following exception:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':compileGroovy'.

Caused by: groovy.lang.GroovyRuntimeException: Conflicting module versions. Module [groovy-all is loaded in version 2.4.11 and you are trying to load version 2.4.7
... 15 more
The only way we found to avoid this exception is to add
configurations.all
{
resolutionStrategy
{
force 'org.codehaus.groovy:groovy-all:2.4.11'
}
}
Is that really the way to go? Could it be that in Gradle 4.0 localGroovy() pulls in the wrong version, or is there another solution?
