Integration between Toggl time tracker and Google Calendar

Creates Google Calendar events for Toggl time entries

Configuration notes

• Create the jar: mvn clean package
• Create a file toggl-gcal-integration.json and put it in the same directory as the jar. It should look like

{
    "lastSuccessfulRunTime": "2023-05-25T13:38:50.857541",
    "calendarId": "[email protected]",
    "togglToken": "----Toggl API token----",
    "togglWorkspaceId": "----Toggl Workspace ID----",
    "timezone": "America/Chicago"
}

where the calendarId is retrieved from the calendar's settings ("Integrate calendar" section).

• Enable the Google Calendar API
• Create an OAuth 2.0 Client ID
• Because the script is running on a headless server, execute the program locally and grant the application permission to generate the tokens/StoredCredential, then move that directory and its contents to the jar directory
• Schedule the jar to be run via a shell script using cron: for every hour,
