### `-tf-device-cluster-outlining`

_Outlines regions of tf_device.cluster operations_

This pass outlines the body of a `tf_device.cluster` into a function and
replaces the `tf_device.cluster` op with an equivalent `tf_device.cluster_func`

  for (func::FuncOp func_op : getOperation().getOps<func::FuncOp>()) {
    if (functions_to_skip.contains(func_op)) {
      OpBuilder builder(func_op);
      // Mark this function as being skipped in island outlining.
      func_op->setAttr(mlir::TF::kSkipIslandOutlining,
                       builder.getBoolAttr(true));
      continue;
    }

We will start by outlining the things you should consider when migrating a build from Ant to Gradle and offer some general guidelines on how to proceed.
