If you can't seem to run `gradle clean`, you might want to use this and replace the `**/expanded.lock` with the problem file.

clean-gradle.groovy

// Removing all files but the expanded.lock
task customClean(type: Delete) {
    // Specify the files or directories to delete
    // delete 'otherDirectory'

    // Remove all files except that one lock file
    def files = []

    fileTree("build")
    .exclude('**/expanded.lock')
    .visit { FileVisitDetails fvd ->
        files << fvd.file
    }

    files.reverse()
    .each { f ->
        def file = file(f)
        if (!file.exists()) return;
        if ((file.isDirectory() && file.list().size() == 0)
            || !file.isDirectory())
                delete f
    }

}

clean.dependsOn customClean
clean.enabled = false
