Boglarka Egyed commented on SQOOP-3389:
---------------------------------------
[~devin.bost] your error log seems very odd to me, all the URLs are like this:
{noformat}
url=https://repository.cloudera.com/content/repositories/releases/xxxxx{noformat}
I don't understand why it tries to resolve every dependency from
{{repository.cloudera.com.}} Do you maybe use some extra configuration in your
environment? Where did you get the Sqoop source from?

> When building Sqoop 1.4.7 with Java SDK 1.6.0_45 and Ant 1.7.1 on Windows in
> MinGW64, I obtain these build errors:
> [ivy:resolve] Server access Error: Remote host closed connection during
> handshake
> url=https://repository.cloudera.com/content/repositories/releases/org/apache/avro/avro-mapred/1.8.1/avro-mapred-1.8.1-hadoop2.pom

> I experienced similar build errors on a different project, which I traced to
> this issue:
> [https://stackoverflow.com/questions/21245796/javax-net-ssl-sslhandshakeexception-remote-host-closed-connection-during-handsh/22629008]
> The problem, however, is that because this particular build of Sqoop requires
> Java 1.6, TLS v1.2 is unsupported, according to here:
> [https://stackoverflow.com/questions/33364100/how-to-use-tls-1-2-in-java-6]
> which is a problem because some public repositories have dropped support for
> TLS versions prior to 1.2, as reported here:
> [https://github.com/Microsoft/vcpkg/issues/2969]
> and here:
> [https://blog.github.com/2018-02-23-weak-cryptographic-standards-removed/]
> If it is impossible now to pull the upstream dependencies when building via
> Ant due to TLS 1.2 being unsupported in Java 1.6, then this is a critical
> dependency conflict.
> If additional configuration steps are required to be able to successfully
> build, they are not documented in any of the Sqoop documentation that I have
> found.
