Failed to create catalog at

Error message

Failed to create catalog at: ${path}

What it means

CatalogService.writeCatalog wraps an IOException with message 'Failed to create catalog at: <absolute path>' when it cannot create the catalog file or its parent directories. The condition is: the file does not exist, parent mkdirs() failed, and createNewFile() also failed. The IOException is then rethrown as a RuntimeException, so callers see a wrapped unchecked exception.

Solutions

1. Check permissions on the parent directory of the catalog path and ensure the process user can write there
2. Ensure the parent path is a directory, not an existing regular file (remove/rename the conflicting file)
3. Free disk space or point the catalog location to a writable path (configure catalog location explicitly)

Example fix

// before
ls -l ~/.quarkus  // 'config' exists as a FILE -> mkdirs fails

// after
mv ~/.quarkus/config ~/.quarkus/config.bak && mkdir ~/.quarkus/config

File catalogFile = catalog.getCatalogLocation().map(Path::toFile).orElse(null);
if (catalogFile != null) {
    File parent = catalogFile.getParentFile();
    if (parent != null && !parent.isDirectory() && !(parent.exists() || parent.mkdirs()))
        throw new IllegalStateException("Cannot create catalog dir: " + parent);
    if (!catalogFile.canWrite() && catalogFile.exists())
        throw new IllegalStateException("Catalog file not writable: " + catalogFile);
}

try {
    catalogService.writeCatalog(catalog);
} catch (RuntimeException e) {
    if (e.getCause() instanceof IOException io && io.getMessage().startsWith("Failed to create catalog")) {
        // fix permissions / remove conflicting file, then retry once
    } else throw e;
}

When it happens

Trigger: Calling writeCatalog when the catalog's parent directory cannot be created (permissions, path is a file, read-only filesystem) and the catalog file itself cannot be created.

Common situations: Read-only home directory or $QUARKUS_USER_HOME; a file exists where the catalog directory should be; disk full; sandboxed CLI environment blocking writes to the config dir.
