enbeet is a modern Java NBT library. Its codebase is intentionally small and easy to understand. It makes extensive use of the Optional API to make null handling much more explicit and safer.
Enbeet is on Maven Central, so you don't need to include any repositories to use it. Simply add the following to your pom.xml:
<dependency>
<groupId>org.mattrick</groupId>
<artifactId>enbeet</artifactId>
<version>1.0.2</version>
</dependency>// Reading NBT
NBTReader reader = new NBTReader(new FileInputStream("example.nbt"));
NBTCompound compound = reader.read();
// Getting a value
System.out.println(compound.getString("test").get());
// Getting a nested value. Each level is a separate argument.
// Note that keys can contain dots unlike other libraries.
System.out.println(compound.getString("nested value", "test.Value", "aaaa").get());
// Setting values
// Note that the type matters here. ints will be written as IntTag, etc...
compound.set(10, "some", "nested", "key");
// Writing NBT
NBTWriter writer = new NBTWriter(new FileOutputStream("output.nbt"));
writer.write(compound);
