My legacy Java project in NetBeans no longer compiles and throws runtime exceptions whenever I try to run it. The application is supposed to read five trigger-times from a file and play an audio track exactly at each of those times, every day. Two things must happen: • Fixing packages – several old or missing packages prevent a clean build; update or replace them so Maven/Ant (whichever you prefer) produces a compile-error-free artefact. • Updating old code – bring the deprecated or broken code up to current Java standards so the app runs without warnings or runtime crashes. • Fixing startup launch – when the program auto-starts with the operating-system it should play music at the first scheduled time; right now it only works after I manually close and reopen it. You will be dealing with both compilation and runtime errors, chiefly around the time-reading logic, audio playback, and the startup sequence. Deliver a fully working NetBeans project that: 1. Builds successfully in the latest LTS JDK on both “Clean & Build” and command-line build. 2. Automatically reads the schedule file, launches on system start, and plays the audio at all five times without requiring a restart. 3. Keeps the existing file-based schedule approach so I can still edit times easily. Feel free to use standard Java libraries, Java Sound API, or a lightweight external library if that simplifies audio playback, but keep the final solution dependency-light and well-documented in the code comments.

I can help you. I will resolve the compilation errors by standardizing your dependencies—likely migrating to Maven for better lifecycle management—and replacing deprecated audio calls with the Java Sound API. The startup issue is likely a working directory conflict: when the OS launches the app, it often fails to find the schedule file because the relative path changes. I will implement absolute path resolution and a robust scheduler that doesn't block the UI thread. I’ll also ensure the audio resources are properly released after each trigger to prevent the memory leaks common in legacy Java applications. Your project will be delivered as a clean, buildable NetBeans project compatible with the latest LTS JDK.
