I know there are a lot of differences between our environments, but we don’t have to scroll up very far to find problems with the abbreviated console output configured:

[reporting]
# This cuts down on the verbosity of pants output
# Comment out these lines to see warnings and other output from javac
console_label_format: {
    'COMPILER' : 'SUPPRESS',
  }
console_tool_output_format: {
    'COMPILER' : 'SUPPRESS',
  }
