Update dependency org.graalvm.buildtools:native-maven-plugin to v0.10.0
This library provides a GVariant parser in pure Java.
jgvariant-core provides Decoder<T>, which read a given type of GVariant-encoded value from a ByteBuffer. The class also contains factory methods to acquire those instances.
The various subclasses of Decoder together implement the GVariant serialization specification.
jgvariant-ostree provides instances of Decoder<T> for various GVariant types used in OSTree repositories.
To parse a GVariant value of type "a(si)", which is an array of pairs of String and int, you can use the following code:
record ExampleRecord(String s, int i) {}
var decoder =
Decoder.ofArray(
Decoder.ofStructure(
ExampleRecord.class,
Decoder.ofString(StandardCharsets.UTF_8),
Decoder.ofInt().withByteOrder(ByteOrder.LITTLE_ENDIAN)));
byte[] bytes = ...;
List<ExampleRecord> example = decoder.decode(ByteBuffer.wrap(bytes));
The jgvariant-tool module contains a tool called jgvariant that can be used to manipulate GVariant-formatted files from the command line. Its primary purpose is to enable the scripting of OSTree repository management tasks.
Usage example (dumping the contents of an OSTree summary file):
$ jgvariant ostree summary read ./jgvariant-ostree/src/test/resources/ostree/summary

You can build the tool either as a shaded JAR or as a native executable.
To build and run a shaded JAR:
$ mvn package -pl jgvariant-tool -am -Pshade $ java -jar jgvariant-tool/target/jgvariant-tool-*.jar ...
To build and run a native executable:
$ mvn package -pl jgvariant-tool -am -Pnative $ ./jgvariant-tool/target/jgvariant ...
You can also run the tool directly with Maven using the exec profile:
$ mvn verify -pl jgvariant-tool -am -Pexec -Dexec.args="..."
