Variable hasTile already defined in method hasTile(char)?

Get that 1 error

ScrabblePlayer.java 
public class ScrabblePlayer {
  // A String representing all of the tiles that this player has
  private String tiles;

  public ScrabblePlayer() {
    tiles = "";
  }

  public String getTiles() {
    return tiles;
  }

  public void addTile(char tile) {
    // TODO: Add the tile to tiles
    tiles += tile;
  }

  public boolean hasTile(char tile) {
    // TODO: Determine if user has the tile passed in
     boolean hasTile = tiles.indexOf(tile) == 0;
     boolean hasTile = tiles.indexOf(tile) == -1;
    return true;
    return false;
  }

}

You're declaring it twice, and also have two return statements.

You just need to declare it, assign it, and return it once.

public boolean hasTile(char tile) {
  //declare our variable to hold the true/false result
  boolean hasTile;

  //hasTile is false if the index of the tile is -1, true otherwise
  hasTile = tiles.indexOf(tile) >= 0;

  //return the true/false value we declared
  return hasTile;
}

You could also do this with fewer lines of code

public boolean hasTile(char tile) {
  //If the index of the tile is not -1, then the user has that tile.
  return tiles.indexOf(tile) >= 0;
}
