gctoolkit integration with jar

[AlinaHovakimyan]

Hi everyone, my mvn project works fine with gctoolkit on intelij, but when I create a jar from it, gctoolkit stops to see my implementations/provides for the Aggregation interface. Does anybody know what could be the issue?
here is my build configuration on maven:
<build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <version>3.6.1</version> <executions> <execution> <id>copy-dependencies</id> <phase>package</phase> <goals> <goal>copy-dependencies</goal> </goals> <configuration> <includeScope>runtime</includeScope> <outputDirectory>${project.build.directory}/libs</outputDirectory> </configuration> </execution> </executions> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <version>3.3.0</version> <configuration> <finalName>GCTK_Integration</finalName> <archive> <manifest> <mainClass>org.example.Main</mainClass> <addClasspath>true</addClasspath> <classpathPrefix>libs</classpathPrefix> </manifest> </archive> </configuration> </plugin> </plugins> </build>

And the output I get (there seem some other wornings as well, i just leaved them for the full referance):
% java -jar .//target/GCTK_Integration.jar Hello Apr 30, 2024 1:01:01 PM io.netty.resolver.dns.DnsServerAddressStreamProviders <clinit> WARNING: Can not find io.netty.resolver.dns.macos.MacOSDnsServerAddressStreamProvider in the classpath, fallback to system defaults.

@AlinaHovakimyan There are three ways that you can get gctoolkit to find your Aggregation classes.

1. Call the GCToolKit#loadAggregation(Aggregation) method
2. Use Java modules for your application and add the provides descriptor in a module-info.java file for the Aggregations your application provides.
3. Add service provider configuration files for your Aggregations to the META-INF\services directory of your jar file.

For the service provider approaches, you'll need to call GCToolKit#loadAggregationsFromServiceLoader()

There is also a sample directory in gctoolkit that has an example module-info.
