Since it was mentioned that it works through the SimpleCLI, why not
replicate the same approach by using the setOptions method?
Something along these lines:

Break up the commandline options into a string array:

String[] args = new String[]{
  "-t",
  "src/MostEffective2018.arff",
  "-W",
  "weka.classifiers.trees.RandomForest",
  "--",
  "-I",
  "100",
  "-depth",
  "0",
};

And use these options to configure your class:

BVDecomposeSegCVSub bv = new BVDecomposeSegCVSub();
bv.setOptions(args);
bv.decompose();
System.out.println(bv);

Javadoc with commandline flags:
