IntegTestTask failed because the task path has space

If we run the IntegTestTask, it will create a dir as build/cluster/integTestCluster node0

And If we resolve this path in our codes, it will have escape word like build/cluster/integTestCluster%20node0. Many func will went wrong with this path, like System.load or Open File..

Is there any settings that we could set another integTestCluster path without space or any other escape word?
