Error message

e.getMessage()

What it means

UncompressedFileTask.call() wraps any exception raised while scanning the APK for uncompressed entries into a TaskExecuteException with message e.getMessage(). It is a generic wrapper; the actionable information is in the cause.

Solutions

1. Check e.getCause() for the real failure and its stack trace.
2. Validate the APK opens as a zip (e.g. unzip -t app.apk) before running.
3. Rebuild/re-download the APK if corrupt.
4. Check file read permissions for the user running matrix.

Example fix

// before
catch (Exception e) { log.warn(e.getMessage()); }
// after
catch (TaskExecuteException e) {
    Throwable cause = e.getCause();
    log.error("UncompressedFileTask failed: " + e.getMessage(), cause);
}

try {
    taskResult = task.call();
} catch (TaskExecuteException e) {
    Throwable cause = e.getCause();
    if (cause instanceof ZipException || cause instanceof IOException) {
        log.error("APK unreadable/corrupt: {}", cause.getMessage(), cause);
    } else {
        log.error("UncompressedFileTask failed", cause);
    }
}

When it happens

Trigger: IOException opening/reading the APK (corrupt or truncated file), ZipException on a non-zip file, or errors building the JSON result.

Common situations: Pointing at a partially downloaded/corrupt APK; APK replaced on disk mid-run; file permission problems in CI workspaces.
