Yes, PowerNBT 0.7.1 beta and 0.7.3 tested with

• craftbukkit 1.7.2-R0.3
• mcpc-plus-1.7.2-R0.4-forge1033-B50

@patey5

PowerNBT 0.6 does not have access to nbt data created by mod.

I recommend to use PowerNBT 0.7.3 (or later) and new API
http://dev.bukkit.org/bukkit-plugins/powernbt/pages/api-0-7/

// get nbt manager
NBTManager manager = NBTManager.getInstance();
// read forge nbt data
NBTCompound forgeData = manager.readForgeData(player); 
// -- do some with forgeData
// save forge data
manager.writeForgeData(player,forgeData);

or old API:

// create container
NBTContainerEntity con = new NBTContainerEntity(player);
// read tag
NBTTagCompound tag = (NBTTagCompound) tag.getTag();
// read forge data (tag "ForgeData" available since 0.7.1 beta)
NBTTagCompound forgeData = (NBTTagCompound) tag.get("ForgeData");
// -- do some with forgeData --
// save
tag.put("ForgeData",forgeData);
con.setTag(tag);

I do not think it's necessary. You can select block by:
/nbt * as %block
+right-click on block
and use it:
/nbt %block

nothing more.

If plugin does not work, send me error message and I will try to solve problem.

Version 0.7.3 tested with craftbukkit:1.7.9-R0.2-SNAPSHOT

Wait for approving

or you can download it now from maven repository.

Fix PowerNBT 0.7.1 for MCPC-Plus 1.6.4:

1. create file plugins/PowerNBT/classmap.yml with content:
   Packet: net.minecraft.network.packet.Packet
2. add line to plugins/PowerNBT/config.yml:
   classmap: classmap.yml

This fix will not be required for the following versions

@TheAndrey

Исправлю в ближайшее время

UPD:
Готов фикс, см. сообщение выше.
В следующих версиях фикс не потребуется.

@TheCoolGuy123_5_Minecraft_

copy file PowerNBT.jar!/en.yml to plugins/PowerNBT/lang/my_en.yml
and add "lang: my_en" to the config file plugins/PowerNBT/lang/config.yml

PowerNBT v0.7.1 beta

Tested with:

• search offline player file by UUID
  old version:
  /nbt gz:world/playerdata/0a12e6c1-babe-cafe-d01d-c0ffeedeadc7.dat
  this version:
  /nbt @PlayerName
  
• added tag ForgeData for entities
  You can store you can store any data to compound "ForgeData"
  /nbt id123(Cow) ForgeData.isSuperCow = true
  
• Class mapping
  Forge 1.4.7 require class mapping
  You need to add
  classmap: classmap.yml
  to PowerNBT config plugins/PowerNBT/config.yml
and create file plugins/PowerNBT/classmap.yml with this content:

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

@TheKitsch

Install plugins:
PowerNBT + VarScript + lib:Groovy + VarScript:PowerNBTExt
And now you can write scripts like this:

me.getItemInHand().nbt {
    it.display = [
        Name: "Example",
        Lore: ["-l","-o","-r","-e"] 
    ]
    it.someNumber = 42 as short
}

or this:

me.addNbt(
    HealF: 10 as float,
    ForgeData:[myString: "value"] 
)

and it possible to load scripts from pastebin.

@blablubbabc

Please check version 0.7.1
first command:
/nbt debug on
and then use your commands
If an error occurs, I would like to see the log file. Please attach it to the pastebin.com

I will try to update the plugin soon.
