It runs a Gradle command to list outdated dependencies, identifies major version changes, and compares current versus latest versions. Libraries that are already up-to-date are skipped, while outdated ones are flagged. Major updates can automatically modify your build.gradle file, and Slack messages notify your team about which dependencies were updated or already up-to-date. This ensures your project stays current without manual tracking.\n\n## Setup Steps\n**1.** Connect an SSH account to access your project folder.\n\n**2.** Configure the schedule trigger (e.g., every 30 days at 10:30 AM).\n\n**3.** Set up Slack credentials and select the channel for notifications.\n\n**4.** Confirm the workflow nodes are linked in this order: Run Gradle \u2192 Extract Updates \u2192 Mark Major \u2192 Check Version \u2192 Conditional \u2192 Update Gradle / Notify Slack.\n\n**5.** Activate the workflow to run automatically and start receiving update notifications."
