1669651 - Error in glean build files breaks mach test

Status: RESOLVED DUPLICATE of bug 1669413

(Data Platform and Tools :: Glean: SDK, defect)

Description

[Simon Giesecke [:sg] [he/him]]

When running e.g. ./mach test --headless netwerk/cookie/test/browser/browser_indexedDB.js, I get the following error:

Test configuration changed. Regenerating backend.
Error running mach:

    ['test', '--headless', 'netwerk/cookie/test/browser/browser_indexedDB.js']

The error occurred in code that was called by the mach command. This is either
a bug in the called code itself or in the way that mach is calling it.
You can invoke |./mach busted| to check if this issue is already on file. If it
isn't, please use |./mach busted file test| to report it. If |./mach busted| is
misbehaving, you can also inspect the dependencies of bug 1543241.

If filing a bug, please include the full output of mach, including this error
message.

The details of the failure are as follows:

BuildReaderError: 
==============================
FATAL ERROR PROCESSING MOZBUILD FILE
==============================

The error occurred while processing the following file:

    /home/simon/work/mozilla-unified/toolkit/components/glean/metrics_index.py

This file was included as part of processing:

    /home/simon/work/mozilla-unified/toolkit/components/glean/moz.build

The underlying problem is a Python syntax error on line 0:

    None

Fix the syntax error and try again.
