Possible workaround for IntelliJ's outstanding multi-project Gradle bug

[Octogonapus]

Try putting this in the wrapper task configuration to possibly help IntelliJ figure out what Gradle to use:

    doLast {
        /*
         * Copy the properties file into the buildSrc project.

        val buildSrcWrapperDir = File(rootDir, "buildSrc/gradle/wrapper")
        GFileUtils.mkdirs(buildSrcWrapperDir)
        copy {
            from(propertiesFile)
            into(buildSrcWrapperDir)
        }
    }
