Maven artifact beam-sdks-java-core does not have dependencies specified as "compile".

This is a followup of iemejia's finding:

Just double checked with today's SNAPSHOTs after the merge and the pom of core is not modified, however the deps look good in master, not sure if the change was applied before the SNAPSHOT generation, but still to double check.
https://repository.apache.org/content/repositories/snapshots/org/apache/beam/beam-sdks-java-core/2.19.0-SNAPSHOT/beam-sdks-java-core-2.19.0-20191213.072102-9.pom

in jsr305 dependency declaration for Nullable class.

Other 4 dependencies are not found in the snapshot pom either:

  compile library.java.antlr_runtime
  compile library.java.protobuf_java
  compile library.java.commons_compress
  compile library.java.commons_lang3

Compile-declared dependencies needed at runtime?

protobuf-java

They are shaded. For example, Beam's TextBasedReader uses com.google.protobuf.ByteString from protobuf-java. The shaded ByteString class is in the published JAR file:

suztomo-macbookpro44:beam suztomo$ jar tf ~/Downloads/beam-sdks-java-core-2.16.0.jar |grep protobuf.ByteString
org/apache/beam/repackaged/core/com/google/protobuf/ByteString$1.class

commons-compress

They are shaded. For example, Beam's org.apache.beam.sdk.io.Compression uses org.apache.commons.compress.compressors.bzip2.BZip2CompressorInputStream. The shaded class is in the published JAR file:

suztomo-macbookpro44:beam suztomo$ jar tf ~/Downloads/beam-sdks-java-core-2.16.0.jar |grep BZip2CompressorInputStream
org/apache/beam/repackaged/core/org/apache/commons/compress/compressors/bzip2/BZip2CompressorInputStream$Data.class
org/apache/beam/repackaged/core/org/apache/commons/compress/compressors/bzip2/BZip2CompressorInputStream.class

commons-lang3

They are shaded. For example, Beam's org.apache.beam.sdk.io.LocalFileSystem uses org.apache.commons.lang3.SystemUtils. The shaded class is in the published JAR file:

suztomo-macbookpro44:beam suztomo$ jar tf ~/Downloads/beam-sdks-java-core-2.16.0.jar |grep SystemUtils
org/apache/beam/repackaged/core/org/apache/commons/lang3/SystemUtils.class

antlr-runtime

Same.

suztomo-macbookpro44:beam suztomo$ jar tf ~/Downloads/beam-sdks-java-core-2.16.0.jar |grep org.antlr.v4 |head
org/apache/beam/repackaged/core/org/antlr/v4/
org/apache/beam/repackaged/core/org/antlr/v4/runtime/
org/apache/beam/repackaged/core/org/antlr/v4/runtime/ANTLRErrorListener.class
