Missing classes in artifact

I noticed that the artifacts
- [`com.google.cloud.datalineage:producerclient-java8:1.0.0` ](https://mvnrepository.com/artifact/com.google.cloud.datalineage/producerclient-java8/1.0.0)
- [`com.google.cloud.datalineage:producerclient:1.0.0`](https://mvnrepository.com/artifact/com.google.cloud.datalineage/producerclient/1.0.0)

do not contain any shaded libs. The build script contains following part
```
shadowJar {
archiveBaseName.set('data-lineage-producer-java-library')
relocate 'com.google.protobuf', 'datalineage.shaded.com.google.protobuf'
relocate 'com.google.guava', 'datalineage.shaded.com.google.guava'
relocate 'com.google.api', 'datalineage.shaded.com.google.api'
relocate 'com.google.auth', 'datalineage.shaded.com.google.auth'
relocate 'io.grpc', 'datalineage.shaded.io.grpc'
relocate 'com.google.common', 'datalineage.shaded.com.google.common'
relocate 'com.google.gson', 'datalineage.shaded.com.google.gson'
relocate 'META-INF/native/libio_grpc_netty_shaded_netty', 'META-INF/native/libdatalineage_shaded_io_grpc_netty_shaded_netty'
relocate 'META-INF/native/io_grpc_netty_shaded_netty', 'META-INF/native/datalineage_shaded_io_grpc_netty_shaded_netty'
mergeServiceFiles()
}
```
and when I build the library locally, all the shaded libraries are present in the jar. So maybe there is an issue with release process.
