Following this checklist to help us incorporate your
contribution quickly and easily:

• Your pull request should address just one issue, without pulling in other changes.
• Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
• Each commit in the pull request should have a meaningful subject line and body.
  Note that commits might be squashed by a maintainer on merge.
• Write unit tests that match behavioral changes, where the tests fail if the changes to the runtime are not applied.
  This may not always be possible but is a best-practice.
• Run mvn verify to make sure basic checks pass.
  A more thorough check will be performed on your pull request automatically.
• You have run the integration tests successfully (mvn -Prun-its verify).

@cstamas Any idea how to implement that with minimal effort?

[cstamas]

maven-resolver/maven-resolver-spi/src/main/java/org/eclipse/aether/spi/connector/transport/PutTask.java

Lines 58 to 63 in 1f01b66

	public InputStream newInputStream() throws IOException {
	if (dataPath != null) {
	return Files.newInputStream(dataPath);
	}
	return new ByteArrayInputStream(dataBytes);
	}

PutTask carries either a file (File in Resolver 1 or Path in Resolver 2) or handful of bytes (as byte[]). Also is a final class, so maybe we just need to expose this?

Came up with a simpler solution based on Supplier<ReadableByteChannel> in 82f6bda.
