Plugin doesn't work, no errors in console.

Hi Bukkit People,

I'm having a problem. I'm trying to do code in my plugin, but it just doesn't work. Whenever I check console, there's no errors. All I know is that stuff isn't running. Any ideas on what to do?

public void OnEnable() {
Main.instance = this;

PluginManager m = getServer().getPluginManager();

System.out.println(instance.toString());
System.out.println("okay");
getCommand("test").setExecutor(new TestCommand());
}


public void OnDisable() {
System.out.println("Disabling plugin.");
}

public void onBlockBreak(BlockBreakEvent event) {
Bukkit.broadcastMessage("hey lol");
event.setCancelled(true);
}

public void saveHashMap(HashMap<String, String> hm, String hashName) {
// Map<String, Object> someMap = new HashMap<String, Object>();
for (Object key : hm.keySet()) {
this.getConfig().set(hashName + "."+key, hm.get(key));
}
saveConfig();
}

public HashMap<String, String> loadHashMap(String hashName) {
HashMap<String, String> hm = new HashMap<String, String>();

for (String key : this.getConfig().getConfigurationSection(hashName).getKeys(false)) {
hm.put(key, (String) this.getConfig().get(hashName + "."+key));
